A database is a system that helps you store and organize information in a way that you can easily find and use it later. There are many different types of databases, including relational, non-relational, graph, and more.

Relational databases are the most common type, and they are made up of tables with rows and columns. Each row represents a single record, and each column represents a different attribute of that record. The data in a relational database is organized into tables based on relationships between the different pieces of information.

Non-relational databases, on the other hand, are more flexible and can store data in a variety of formats. Graph databases are designed to store data in nodes and edges, which can be used to represent complex relationships between pieces of data.

Database management is important because it ensures that information is stored in an organized and secure way. This makes it easier to access, search, and update the data as needed.
