Overview of Database Management Systems

A structured collection of data designed for efficient retrieval and management.

Databases enable computers to efficiently store and manage large amounts of data.

A software system that allows users to create, organize, and access databases.

A DBMS acts as an intermediary between the database and users, controlling access and facilitating interactions with the data.

Organizing data into tables in a database allows for defining clear relationships between different pieces of information.

One of the primary reasons for using a DBMS is to protect sensitive information from unauthorized access.

The ability of a DBMS to allow changes in the database structure without affecting applications using the data.

The network model represents data as nodes connected by edges, creating a graph-like structure.

A DBMS allows users to retrieve specific information from the database using queries, making data retrieval efficient.

Transaction management in a DBMS ensures the integrity and consistency of the database by managing changes as a set of operations.
