Smart_Store: Triple-Lock Validation for Secure Data Imports

Emmanuel Victor — Mon, 01 Dec 2025 12:21:41 +0000

Previously, I talked about schema guides and versioning in Smart_Store; today, I will discuss schema validation during file import.

Data is the lifeblood of modern applications. But here’s the truth: not all data is trustworthy. In fact, one of the biggest challenges developers face is ensuring that the information flowing into their systems is both authentic and safe.

Most frameworks rely on schema validation alone. They check if a file has the right fields, types, and formats. That’s useful, but it’s not enough. A clever programmer, or even someone working within the same ecosystem, could craft a file that looks valid but isn’t truly recognized by the system.

That’s why I designed Smart_Store with a different philosophy. Instead of relying only on schemas, Smart_Store enforces triple-lock validation using ID, Type, and Tag name. This approach makes Smart_Store tamper-resistant, even against insiders who might try to bypass the rules.

The Triple-Lock System Explained
Think of Smart_Store as a vault. To get inside, you don’t just need one key; you need three.

-ID (Identity Lock): Every object is assigned a unique ID by Smart_Store itself. This ID acts like a fingerprint. If an imported file carries an ID that doesn’t match the registry, it’s discarded immediately. No exceptions.

-Type (Structural Lock): Even with a valid ID, the system checks the object’s type. It must match the registered schema (like User, Product, or Transaction). This ensures the structure is exactly what Smart_Store expects.

-Tag (Context Lock): Finally, the tag ensures the object belongs in the right logical category. This prevents misplacement or misuse of data.

Together, these three checks form a pipeline of trust: File → ID Check → Type Check → Tag Check → Accepted or Discarded.

Example in Practice
Here’s a simplified version of how Smart_Store enforces validation:

bool validateObject(const Object& obj) {
    if (!registry.hasID(obj.id)) return false;             // ID check
    if (obj.type != registry.getType(obj.id)) return false; // Type check
    if (obj.tag != registry.getTag(obj.id)) return false;   // Tag check
    return true;
}

Why This Matters
Other systems often stop at schema validation. That’s flexible, but it leaves room for manipulation. Some add checksums or signatures, which ensure integrity but don’t prove ownership. Others use metadata tags, which help with organization but can be spoofed.

Smart_Store’s triple-lock approach closes all these gaps. By requiring ID, Type, and Tag to match, it ensures that only registered, authentic objects can enter. Even if a file looks structurally correct, it won’t pass unless it’s truly recognized by the system.

This makes Smart_Store ideal for industries where data authenticity and security are non-negotiable:

Finance: Preventing fraudulent transactions.
Healthcare: Ensuring patient records are genuine.
IoT: Blocking rogue devices from injecting fake logs.
Enterprise systems: Guaranteeing that only trusted data flows through.

Final Thought
Smart_Store isn’t just a framework; it’s a philosophy. It says: “Only what the system itself recognizes can exist inside it.” That transforms Smart_Store from a simple data manager into a guardian of integrity.

In a world where data can be manipulated, spoofed, or faked, Smart_Store’s triple-lock validation ensures that your system remains secure, consistent, and trustworthy.

Smart_Store Schema Guide: Future-Proofing Your Data with Versioning

Emmanuel Victor — Mon, 17 Nov 2025 09:02:50 +0000

Let’s be honest—data doesn’t stay still. As your application evolves, so do your data models. New fields get added, formats change, and business logic shifts. But if you’ve ever tried to update a live system without breaking everything, you know how painful schema evolution can be.

That’s where Smart_Store steps in with a clean, reliable solution: schema-based item management with versioned migrations.

Why Schema and Versioning Matter

Smart_Store treats your data like a first-class citizen. Every item—whether it’s a User, Product, or Transaction—has a defined schema that outlines its structure. And when that structure changes, Smart_Store doesn’t panic. It tracks schema versions and automatically upgrades legacy data during import.

Benefits at a glance:

Backward compatibility with older formats
Safe evolution of your data models
Automatic upgrades during import/export
Cleaner, more structured data that adapts to your business needs

Real-World Example: Schema-Based Item Management
Here’s a practical example that shows how schema and versioning work in Smart_Store. This isn’t just theory—it’s code you can run today.

// Smart_Store Example: Schema-Based Item Management
// Author & Architect: Ndiukwu

#include "t_manager/ItemManager.h"
#include "err_log/Logger.hpp"
#include <iostream>
#include <string>
//#include <nlohmann/json.hpp> // Optional JSON library

struct WithSchema {
    std::string name;
    int age;
    std::string email;

    static nlohmann::json schema() {
        return {
            {"type", "object"},
            {"properties", {
                {"name", {{"type", "string"}}},
                {"age", {{"type", "integer"}}},
                {"email", {{"type", "string"}, {"format", "email"}}}
            }},
            {"required", {"name", "age", "email"}}
        };
    }

    NLOHMANN_DEFINE_TYPE_INTRUSIVE(WithSchema, name, age, email)
};

int main() {
    ItemManager manager;

    manager.addItem(std::make_shared<WithSchema>(WithSchema{"Ada", 30, "ada@example.com"}), "schema1");

    manager.exportToFile_Json("test_schemas.json");
    manager.displayAll();

    auto value = manager.getItem<WithSchema>("schema1")->email;
    std::cout << "Email from imported item: " << value << std::endl;

    return 0;
}

Expected Output

This example shows how Smart_Store validates structure, serializes data, and retrieves it cleanly—all while respecting the schema definition.

Versioned Migrations: Keeping Data in Sync

Let’s say your User schema evolves from version 1 to version 3. Maybe you added a phoneNumber field or changed age to birthDate. Smart_Store handles this with migrationRegistry—a set of upgrade functions that transform older data into the latest format during import. No manual patching. No brittle hacks. Just clean, versioned upgrades.

Another Practical Example: Evolving the Schema
Imagine you want to add a role field to the WithSchema struct. You’d bump the version, define the new schema, and register a migration function like this:

migrationRegistry.registerUpgrade<WithSchema>(2, 3, [](WithSchema& legacy) {
    legacy.role = "Staff"; // default role for older data
});

Now, any item from version 2 gets upgraded to version 3 automatically. That’s how Smart_Store keeps your data future-proof.

Final Thoughts
Smart_Store’s schema and versioning system isn’t just a technical feature—it’s a philosophy. It’s about treating your data with respect, anticipating change, and building systems that last.

If you’re tired of fragile migrations and messy data formats, give Smart_Store a try. It’s built for developers who care about structure, safety, and scalability.

Smart_Store API Guide: Threading for High-Performance Item Management

Emmanuel Victor — Mon, 10 Nov 2025 07:32:09 +0000

Modern applications rarely run in isolation. They often need to handle multiple users, concurrent requests, and heavy workloads—all without sacrificing reliability. In C++, this challenge is magnified by the complexity of managing shared resources safely. Smart_Store rises to the occasion with a robust multithreading model that ensures smooth, efficient, and safe operations.

Why Threading Matters in Smart_Store
Smart_Store’s threading architecture is designed to keep the system responsive and reliable, even under heavy load or in multi-user environments. By leveraging internal mutexes and thread-safe APIs, Smart_Store guarantees:

Concurrent access without corruption
Performance boosts during bulk operations
Safe shared object management
Scalability for multi-user systems

Example: Simulating Concurrent Users

// Simple thread simulation with ItemManager
void simulateUser(ItemManager& manager, int userId) {
    auto itemName = "Item_" + std::to_string(userId);
    auto item = std::make_shared<Item>(Item{itemName});
    manager.addItem(item, "user_tag_" + std::to_string(userId));
    manager.hasItem("user_tag_" + std::to_string(userId));
}

This example demonstrates how multiple threads can safely add items concurrently without data corruption.

Real-World Use Case: Employee Registration System
Beyond simple simulations, Smart_Store threading shines in real-world applications. Consider a scenario where multiple employees are registered simultaneously in a store’s system:

// Include Smart_Store's item management system
#include "t_manager/ItemManager.h"
#include "err_log/Logger.hpp"
#include <iostream>
#include <vector>
#include <thread>
#include <string>
#include <nlohmann/json.hpp>  // For JSON serialization

// Define a User class to represent employees
class User {
public:
    std::string name;
    int id;
    std::string email;
    std::string role;
    int age;

    User(const std::string& name, int id, const std::string& email, const std::string& role, int age)
        : name(name), id(id), email(email), role(role), age(age) {}
    User() : name(""), id(0), email(""), role(""), age(0) {}

    nlohmann::json toJson() const {
        return { {"name", name}, {"id", id}, {"email", email}, {"role", role}, {"age", age} };
    }

    static User fromJson(const nlohmann::json& j) {
        return User(j.at("name"), j.at("id"), j.at("email"), j.at("role"), j.at("age"));
    }
};

// Function to add a User concurrently
void addEmployee(ItemManager& manager, int id) {
    auto user = std::make_shared<User>(
        "User_" + std::to_string(id),
        id,
        "user" + std::to_string(id) + "@store.com",
        "Staff",
        20 + (id % 10)
    );
    manager.addItem(user, "emp_" + std::to_string(id));
}

int main() {
    ItemManager manager;
    std::vector<std::thread> threads;

    // Spawn 3 threads to simulate concurrent employee registration
    for (int i = 0; i < 3; ++i) {
        threads.emplace_back(addEmployee, std::ref(manager), i);
    }

    for (auto& t : threads) t.join();

    std::cout << "All employees added.\n";

    // Retrieve and display employee with tag "emp_1"
    auto importedUser = manager.getItem<User>("emp_1");
    LOG_CONTEXT(LogLevel::DISPLAY, "\n" + importedUser->toJson().dump(4), {});

    // Modify employee email
    manager.modifyItem<User>("emp_1", [](User& user) {
        user.email = "new_email@example.com";
    });

    // Display updated employee data
    importedUser = manager.getItem<User>("emp_1");
    LOG_CONTEXT(LogLevel::DISPLAY, "\n" + importedUser->toJson().dump(4), {});

    return 0;
}

Expected Output

Final Thoughts
This real-world threading example demonstrates how Smart_Store can safely handle concurrent employee registrations, serialize data to JSON, and even modify records—all without race conditions or corruption. It’s a powerful showcase of how Smart_Store threading translates from theory to practice.

Smart_Store API Guide: Exporting and Importing with Confidence

Emmanuel Victor — Sun, 02 Nov 2025 13:06:51 +0000

In the realm of modern C++ development, data persistence and runtime type safety are often treated as afterthoughts—until they become bottlenecks. With Smart_Store, these challenges are not only addressed but elegantly solved. This guide dives deep into the export/import API of Smart_Store, revealing how it empowers developers to serialize complex object graphs with precision, safety, and speed.

Exporting and Importing: The Smart Way
Smart_Store’s export/import system is designed for seamless data persistence, backup automation, and system integration. Whether you're building a game inventory, a configuration manager, or a dynamic asset tracker, Smart_Store ensures your data flows smoothly across sessions and systems.

Key Highlights

Format Flexibility: Supports JSON, XML, CSV, and Binary with embedded type metadata

Here's an example:

#include "t_manager/ItemManager.h"
#include "err_log/Logger.hpp"
#include <iostream>
#include <string>

using namespace std;

class HumanBeing {
public:
    virtual void speak() const = 0;
    virtual void walk() const = 0;
    virtual void eat() const = 0;
    virtual ~HumanBeing() = default;
};

// Example derived class 
class Boy : public HumanBeing {
public:
    std::string name;
    int age;

public:
    // If you have a constructor that takes parameters, make sure to define 
    // the default constructor as well to avoid issues.
    Boy(std::string name, int age): name(name), age(age) {}
    Boy() {}
    ~Boy() {}

    void speak() const override {
        LOG_CONTEXT(LogLevel::DISPLAY, "Hello, I am a boy named: " 
               + name +  " I am " + to_string(age) + " years old.", {});
    }

    void walk() const override {
        LOG_CONTEXT(LogLevel::DISPLAY, "I am walking like a boy named "
                          + name+ ".", {});
    }

    void eat() const override {
        LOG_CONTEXT(LogLevel::DISPLAY, "I am eating like a boy named "
                           + name + ".", {});
    }
};

// Example of a girl
class Girl : public HumanBeing {
public:
    std::string name;
    int age;

public:
    // If you have a constructor that takes parameters, make sure to define 
    // the default constructor as well to avoid issues.
    Girl(std::string name, int age): name(name), age(age) {}
    Girl() {}
    ~Girl() {}

    void speak() const override {
        LOG_CONTEXT(LogLevel::DISPLAY, "Hello, I am a girl named: "
               + name +  " I am " + to_string(age) + " years old.", {});
    }

    void walk() const override {
        LOG_CONTEXT(LogLevel::DISPLAY, "I am walking like a girl named "
                    + name + ".", {});
    }

    void eat() const override {
        LOG_CONTEXT(LogLevel::DISPLAY, "I am eating like a girl named "
                         + name + ".", {});
    }
};

Exports to files
In this section, we will export items in various file formats, specifically JSON and Binary.

Exporting and Importing with JSON

ItemManager manager;
auto Item1 = std::make_shared<Boy>("Tom", 12);
auto Item2 = std::make_shared<Girl>("Alice", 10);

manager.addItem(Item1, "Boy1");
manager.addItem(Item2, "Girl1");

manager.exportToFile_Json("items.json");
manager.importFromFile_Json("items.json");
manager.importSingleObject_Json("items.json", typeid(Boy).name(), "Boy1");

Expected outputs:

manager.exportToFile_Json("items.json");

manager.importFromFile_Json("items.json");

manager.importSingleObject_Json("items.json", typeid(Boy).name(), "Boy1");

Example: Binary API in Action

ItemManager manager;

auto Item1 = std::make_shared<Boy>("Tom", 12);
auto Item2 = std::make_shared<Girl>("Alice", 10);

manager.addItem(Item1, "Boy1");
manager.addItem(Item2, "Girl1");

manager.exportToFile_Binary("items.bin");
manager.importFromFile_Binary("items.bin");
manager.importSingleObject_Binary("items.bin", typeid(Boy).name(), "Boy1");

Exporting and Importing with Binary
Binary serialization offers compactness and speed, making it ideal for performance-critical applications. Smart_Store handles binary export/import with the same rigor as JSON, embedding type metadata and enforcing registration rules.

Expected outputs:
manager.exportToFile_Binary("items.bin");

manager.importFromFile_Binary("items.bin");

manager.importSingleObject_Binary("items.bin", typeid(Boy).name(), "Boy1");

Why typeid Still Matters
Just like with JSON, Smart_Store uses typeid to ensure runtime type safety during binary deserialization. This is especially critical when dealing with STL containers or polymorphic hierarchies, where relying on mangled names or manual identifiers can lead to subtle bugs.

Best Practices

Validate exported files before use
Use consistent tag naming for traceability
Schedule regular backups
Log all operations for auditability
Flush singleton managers to avoid stale data
Test imports with typeid to ensure type safety

Final Thoughts
Smart_Store’s export/import API isn’t just a utility; it’s a philosophy of safe, scalable, and smart data management. By embedding type metadata, enforcing registration discipline, and supporting flexible formats, it gives developers the confidence to persist and restore complex object graphs without fear.

Smart_Store: A Modern C++ API for Scalable Inventory and Object Management

Emmanuel Victor — Sat, 25 Oct 2025 19:52:00 +0000

In today’s software landscape, modularity, performance, and clarity are non-negotiable. That’s why I built Smart_Store, a high-performance, thread-safe inventory manager powered by modern C++ and designed to handle dynamic object lifecycles with elegance.

Whether you're managing vehicles, people, or abstract entities, Smart_Store gives you intuitive APIs and clean architecture to build scalable systems with minimal friction.

Why Smart_Store?

Smart_Store APIs are designed to be:

Intuitive: Add and retrieve items with minimal boilerplate.
Extensible: Store any object of arbitrary type.
Powerful: Every item inherits full capabilities from the ItemManager interface — tagging, querying, exporting, and state tracking.
Thread-safe: Built for concurrent environments without sacrificing performance.

With just a single call to "addItem()", your object is registered automatically and ready to use; no manual bookkeeping, no fragile pointers.

To walk through the integration steps on a new tab: Smart_Store Integration

Example 1: Vehicle Factory System
This example demonstrates how Smart_Store integrates with a factory pattern to dynamically produce and manage vehicle types.

#include "t_manager/ItemManager.h"
#include "err_log/Logger.hpp"
#include <iostream>
#include <chrono>
#include <thread>
#include <unordered_map>
#include <functional>
#include <memory> 
using namespace std;

// Vehicle Hierarchy
class Vehicle {
public:
    virtual void createVehicle() = 0;
};

class Jeep : public Vehicle {     // ----> Jeep class
public:
    void createVehicle() override {
        cout << ":::::::-> Jeep Produced." << endl;
    }
};

class Benz : public Vehicle {    // -----> Benz class
public:
    void createVehicle() override {
        cout << ":::::::-> Benz Produced." << endl;
    }
};

class RollsRoyce : public Vehicle {  // -----> RollsRoyce class
public:
    void createVehicle() override {
        cout << ":::::::-> Rolls-Royce Produced." << endl;
    }
};

class Ferrari : public Vehicle {    // ---> ferrari class
public:
    void createVehicle() override {
        cout << ":::::::-> Ferrari Produced." << endl;
    }
};

//  Factory Logic
class Factory {
public:
    static unique_ptr<Vehicle> vehicleFactory(const string& productType) {
       static unordered_map<string, function<Vehicle* ()>> factoryMap = { 
/* 
  unordered map where a new instance of different vehicles is returned as      
  value
*/
            {"benz", []() { return new Benz(); }},
            {"jeep", []() { return new Jeep(); }},
            {"ferrari", []() { return new Ferrari(); }},
            {"rollsroyce", []() { return new RollsRoyce(); }}
        };
        if (factoryMap.count(productType)) {
            return unique_ptr<Vehicle>(factoryMap[productType]());
        }
        return nullptr;
    }
};

// This function delays the outputs on the client side.
void simulateCheck() { 
    cout << "\n\n \t\t::: Checking ";
    for (int i = 0; i <= 4; ++i) {
        this_thread::sleep_for(chrono::milliseconds(500));
        cout << ".";
    }
    cout << endl;
}

//Interface for car manufacturing.
class I_Client {
public:
  void garage() { // Here is the client class that displays the data.
      system("cls");
      cout << "\n\n::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::" << endl;
      cout << "*************** Vehicles available ***************\n\n";
      cout << "::: benz" << endl;
      cout << "::: jeep" << endl;
      cout << "::: ferrari" << endl;
      cout << "::: rollsroyce";
      cout << "\n\n::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::" << endl;
      cout << "Enter Product Type: ";
      string productType;
      cin >> productType;

      auto vehicle = Factory::vehicleFactory(productType);
      system("cls");

      simulateCheck(); 

      if (vehicle) {
          vehicle->createVehicle();
          this_thread::sleep_for(chrono::milliseconds(5000));
          garage();
      }
      else {
          cout << "\n\n \t\t::::::: No such product :::::::" << endl;
          this_thread::sleep_for(chrono::milliseconds(5000));
          garage();
      }
    }
};


//  Smart_Store Integration
int main() {
  ItemManager manager;

  // Item stored and automatically registered.
  auto Item1 = std::make_shared<I_Client>(); 
  manager.addItem(Item1, "car_factory");  
  auto item = manager.getItem<I_Client>("car_factory");
  item->garage();  // Start the client interaction

  return 0;
}

This setup allows users to interactively select and produce vehicles, with Smart_Store managing the lifecycle and access.

Here is the outcome: The output

Example 2: Human Interaction System
This second example showcases Smart_Store’s advanced features like modification, undo/redo, and dynamic interaction.

#include "t_manager/ItemManager.h"
#include "err_log/Logger.hpp"
#include <iostream>
#include <string>

using namespace std;

     If you have a constructor that takes parameters, make sure to define 
     the default constructor as well to avoid issues.
    */ 

    Boy(std::string name, int age): name(name), age(age) {}
    Boy() {}
    ~Boy() {}

    void speak() const override {
         LOG_CONTEXT(LogLevel::DISPLAY, "Hello, I am a boy named: " + name
                +  " I am " + to_string(age) + " years old.", {});
    }

    void walk() const override {
        LOG_CONTEXT(LogLevel::DISPLAY, "I am walking like a boy named "   
                       + name+ ".", {});
    }

    void eat() const override {
        LOG_CONTEXT(LogLevel::DISPLAY, "I am eating like a boy named " 
                   + name + ".", {});
    }
};

// Example of a girl
class Girl : public HumanBeing {
public:
    std::string name;
    int age;

public:
    /*

     the default constructor as well to avoid issues.
    */ 

    Girl(std::string name, int age): name(name), age(age) {}
    Girl() {}
    ~Girl() {}

    void speak() const override {

                       + name + ".", {});
    }
};

int main() {
    ItemManager manager;

    // Add items using constructor
    auto Item1 = std::make_shared<Boy>("Tom", 12);
    auto Item2 = std::make_shared<Girl>("Alice", 10);
    manager.addItem(Item1, "Boy1");
    manager.addItem(Item2, "Girl1");

    // Interact with the Boy by returning the Boy item.
    manager.getItem<Boy>("Boy1")->speak();
    manager.getItem<Boy>("Boy1")->walk();
    manager.getItem<Boy>("Boy1")->eat();

    // Modify Boy
    manager.modifyItem<Boy>("Boy1", [](Boy& item) {
        item.age += 1;
        item.name = "UpdatedTom";
    });

    manager.getItem<Boy>("Boy1")->speak();  // See updated values

    std::cout << "::::::::::::::::::::::::::::::::::::::::::::::\n";

    // Interact with Girl by returning the Girl Item
    manager.getItem<Girl>("Girl1")->speak();
    manager.getItem<Girl>("Girl1")->walk();
    manager.getItem<Girl>("Girl1")->eat();

    /*
      Modify Girl
      This function returns the value for modification or
      change of the value.
    */ 
    manager.modifyItem<Girl>("Girl1", [](Girl& item) {
        item.age += 1;
        item.name = "UpdatedAlice";
    });

    /*
     This function returns the Item with this tag for accessing its value.
    */
    manager.getItem<Girl>("Girl1")->speak();  // See updated values

    std::cout << "::::::::::::::::::::::::::::::::::::::::::::::\n";

    // Undo both modifications
    manager.undo(); // Undo Girl
    manager.undo(); // Undo Boy

    manager.getItem<Boy>("Boy1")->speak();   // Should show "Tom", 12
    manager.getItem<Girl>("Girl1")->speak(); // Should show "Alice", 10

    std::cout << "::::::::::::::::::::::::::::::::::::::::::::::\n";

    // Redo both modifications
    manager.redo(); // Redo Boy
    manager.redo(); // Redo Girl

    manager.getItem<Boy>("Boy1")->speak(); // Should show "UpdatedTom", 13
    manager.getItem<Girl>("Girl1")->speak(); // Should show    
                                             // "UpdatedAlice", 11
    std::cout << "::::::::::::::::::::::::::::::::::::::::::::::\n";

    return 0;
}

This example highlights Smart_Store’s ability to track state changes, support undo/redo operations, and maintain clean object access, all while using modern C++ idioms like lambdas and smart pointers.

Expected output:

If you look very closely at the output, you will realise that the undo/redo methods are doing their job at ease; reverting and tracking each object to its previous state and also restoring it to the current assigned values.

Key Takeaways
Smart_Store abstracts away the complexity of object lifecycle management.

It supports real-time interaction, state tracking, storing objects at runtime, and modification history.

It’s built with modern C++ principles: RAII, smart pointers, lambdas, and clean separation of concerns.

Final Thoughts
Smart_Store isn’t just an API; it’s a blueprint for building scalable, maintainable systems in C++. Whether you're managing vehicles, people, or abstract entities, Smart_Store gives you the tools to build with confidence and focus mainly on logic.

Code should be simple to write, powerful to run, and beautiful to extend. That’s the Smart_Store way. I’m exploring an architectural foundation that unifies different dimensions of programming into a single living structure — one I call Bio-Struct, inspired by biological systems that power Smart_Store.

What Is Smart_Store?

Smart_Store is a modern C++ library I built to simplify dynamic data management. It offers smart memory handling, tagging, undo/redo functionality, and JSON, XML, CSV, and Binary serialization, all designed to help developers write safer, smarter code with clean architecture.

Why I Built It

While working on systems-level projects, I found myself repeatedly solving the same problems around state management, object tracking, and serialization. Smart_Store is my attempt to solve those challenges in a reusable, scalable way.

Key Features

Smart memory handling with dynamic object tracking
Tag-based data organization
Undo/redo stack for state transitions
JSON, XML, CSV, and Binary serialization and deserialization
Clean, reusable architecture
Thread-Safe API for concurrent access and modification

Below is a sample integration of Smart_Store in action:

#include "t_manager/ItemManager.h"

int main() {
  ItemManager manager;

  manager.addItem(std::make_shared<int>(42), "item1");
  manager.displayByTag("item1");

  manager.exportToFile_CSV("backup.csv");

  manager.undo();
  manager.redo();

  manager.removeByTag("item1");
  manager.displayByTag("item1");

  return 0;
}

Expected output:

Common Pitfall I Encountered

During deserialization, I ran into an issue where instantiation fails if a class has only a parameterized constructor. This happens because many serialization frameworks expect a default (no-argument) constructor to create objects before populating their fields.

class Tag {
public:
    Tag(std::string name, int priority);
    // No default constructor
};

This issue may affect serialization, deserialization, or object pooling mechanisms that rely on default instantiation. I’m exploring clean workarounds that don’t compromise class design.
