Database
Data refers to raw, unorganized facts and figures that can be processed to generate meaningful information. A database is a structured system used to store, manage, and retrieve data efficiently for multiple users and applications.
Types of database
1.Relational Database - stores data in tables
(Eg)MySQL, PostgreSQL, Oracle, Microsoft SQL Server.
2.NoSQL(Not Only SQL) Database - unstructured data
Document Databases – Store data as JSON-like documents. (Example: MongoDB)
Key-Value Stores – Store simple key–value pairs for fast lookups. (Example: Redis)
Columnar Databases – Store data by columns for analytics. (Example: Apache Cassandra)
Graph Databases – Store nodes & relationships for connected data. (Example: Neo4j)
3.Object-Oriented Database - object storage
4.Hierarchical Database -tree like structure
Working of Databases
Databases work by organizing and storing information in a structured or unstructured format, allowing easy access, retrieval, and modification. At the core of every database system is the Database Management System (DBMS)- a software layer that acts as an intermediary between users and the raw data.
