Benefits Of Databases: A Quick Guide From Experts

Here in this blog, you will know about the benefits of databases in detail. And all these benefits which we are going to tell you, all are beneficial for you.

Benefits of a Database

There are a number of characteristics that distinguish database policies from the system or file-based policy. This chapter describes the advantages (and features) of the database system.

Self-describing nature of a database system

The database system is referred to as a self-description system because it contains not only the database itself, but also metadata that identifies and describes data and the relationships between tables in the database. This information is used by DBMS or database users if necessary. This separation of data and information about data makes the database system quite different from the traditional file-based system where data definition is part of application software.

Support for multiple views of data

The database supports multiple data views. The view is a subset of the database, which is defined and customized to specific users of the system. Many users in the system may have different views of the system. Each view may contain data that is of interest to the user or user group only.

Sharing of data and multiuser system

Existing database systems are designed for multiple users. That is, it allows many users to access the same database at the same time. This access is achieved through features called synchronization control strategies. These strategies ensure that the data accessed is always correct and that data integrity is maintained.

The design of modern multi-user database systems is a significant improvement over those of the past, which were limited to one person at a time.

Restriction of unauthorized access

Not all users of the database system will have the same access privileges. For example, a user may have access to read only (i.e. the ability to read a file without making changes), while another user may have literacy privileges, namely the ability to read and edit the file. For this reason, the database management system must provide a sub-security system to create, control and restrict different types of user accounts and restrict unauthorized access.

Data independence

Another advantage of the database management system is how data independence is allowed. In other words, system data descriptions or data describing data (metadata) are separated from application software. This is possible because changes in the data structure are processed by the database management system and are not included in the program itself.

Transaction processing

The database management system must include subsystems for synchronization control. This feature ensures that data remains consistent and valid while the transaction is being processed even if many users update the same information.
