Introduction
A Database is a collection of elements or particulars in layman's terms. In computing, it is defined as the structural and organized collection of information, which is in the electronic format of a computer system. This database is controlled by a management system that is called DBMS (Database management systems).
You might consider a spreadsheet and a DBMS to be the same concepts. But, in a spreadsheet, it is more useful to limited users and ideal for a small chunk of data to be manipulated. The maintenance of spreadsheets can invade security as it is easily accessible.
The data in a database is stored in the format of rows and columns such that the accessibility of elements does not become messy. This data can be easily updated, deleted, modified, or created.
The language that is most commonly used to manage a DBMS is SQL (Structured query language). It is a programming language that is used by various types of DBMS to maintain, update, or organize the database.
Types of database
Some of the database categories are as follows:
Distributed database
Cloud database
Relational database
NoSQL database
Multi-Model database
Cloud database
Self-driving database
What is a DBMS?
To operate a database, a comprehensive database software program is required, which is called DBMS. It acts as a bridge between the database and the user operating on the database. This bridge enables the end users to manage, update, delete or create the information according to the database.
Examples of DBMS are as follows: MySQL, ORACLE database, Microsoft
Access, etc.
Characteristics of DBMS
Following are some of the characteristics of DBMS:
Real-world entity
Self-explaining nature
Data atomicity
Concurrent Access
Any type of data storage
Integrity
Ease of access
ACID property
Benefits of using a Database Management System
The following are the benefits of using a DBMS:
Simple: The architecture of the DBMS is not much complex and is easily understandable. All the CURD (Create, Update, Insert, Delete) operations are easy to visualize and implement. Relational algebra is used as a fundamental block in DBMS, which makes it more convenient to use.
High Security and improved Data sharing: The systems promote users to share the data easily, quickly, and in a presentable manner. The quick solution to database queries promotes faster retrieval with a high accuracy rate. For the sales department, the presentation and upskilling of the sales cycle have become quite smooth. The DBMS provides high security which prevents the sensitive data in the database to be exposed to the outer world. The failover risk is minimized due to high-security measures and hence, the data loss is saved.
Efficient data integration: With the help of a DBMS, a clear picture of the operations is depicted and their relationship with other segments in the organization. The operations can also be automated to minimize manual work. Integration becomes standardized with a flexible database by implementing data sets into custom workflows.
Privacy: Role-based access can be provided in the database which increases high security of data prevention. The users are provided read access by default and the access rights increase with the responsible or reporting person in the organization. The admin and the user rights can also be recreated with special privileges.
Reliability and consistency: The database can experience multiple duplicate changes made by various team members. The overwrite can be equalized by using a correct data quality tool in the database. Hence, the data in the database remains consistent and the organization is saved.
High productivity: The tools used in DBMS represent the data in such a way that it gives a clear picture of the business which promotes end-users to take quick decisions on any failure or economy of the organization.
Data Transfer: DBMS provides a place that gives users the privilege of better-managed data. The changes made in the environment are reflected on the go so that the end-users can have a quick update about the results. It is done with the help of indexing. You can learn more about the same in this tutorial on indexing in DBMS by Scaler topics.
Data abstraction: The efficiency of the database can be improved by integrating some complex algorithms by the developers. The feature is then made available to the users to use in the database by abstracting the algorithm behind it. Hence, it makes the platform more interactive after such new implementations.
Backup and Recovery: The DBMS automatically maintains a backup of the data and stores it with itself. No periodic backup needs to be scheduled by the end-users. It also restores the database after a crash or system failure.
Conclusion
In this article, we have learned that the organized collection of data is called a database. A spreadsheet can also maintain a database but it is for small sets of data and limited users can be provided the access to the spreadsheets.
A DBMS is a computer software program that helps to manage the database.
The advantages of a DBMS are security, Data transfer, Backup, and recovery, increased productivity, quick decisions due to an engaging view of the data, etc.
