Databases

Databases are a technology category that refer to organized collections of data that can be easily accessed, managed, and updated. They are used to store information such as customer records, product information, financial data, and more. Databases can be relational or non-relational, with relational databases being the most common type. They use tables with rows and columns to organize data and establish relationships between them. Non-relational databases, on the other hand, use various techniques such as key-value pairs, document-based structures, or graph structures to manage data. Databases are often used in conjunction with software applications to provide efficient data storage and retrieval, allowing users to quickly access relevant information. They are also used for analytical purposes, where large amounts of data are processed to generate insights and support decision making.
