Understanding Database Management Systems (DBMS)

A Database Management System (DBMS) is a software system that enables users to define, create, maintain, and control access to databases. It acts as a bridge between the database and end-users or application programs, ensuring data is well-organized and easily accessible.

Different Types of Databases

There are various types of databases, each with unique structures and methods of storing and managing data. Some common types include:

1. Hierarchical Databases

   In a hierarchical database, data is structured in a tree-like format where each record has a single parent record and can have multiple children records. This model is ideal for representing one-to-many relationships.

2. Network Databases

   Network databases also adopt a tree-like structure but offer more flexibility, allowing records to have multiple parent and child records. This model is beneficial for representing intricate data relationships.

3. Relational Databases

   Relational databases are founded on the relational data model, organizing data into tables with rows and columns. This model utilizes Structured Query Language (SQL) to efficiently manage and manipulate data.
