What is a database?
A database is a warehouse that organizes, stores, and manages data according to data structures.
Each database has one or more different APIs for creating, accessing, managing, searching, and replicating the data it stores.
We can also store data in files, but reading and writing data in files is relatively slow.
Therefore, we now use relational database management systems (RDBMS) to store and manage large amounts of data. The so-called relational database is a database based on the relational model, which uses mathematical concepts and methods such as set algebra to process data in the database.
