sqlDBs

sqlDBs, also known as SQL databases or relational databases, are a type of database that stores and provides access to data points that are related to one another. They are based on the relational model, which organizes data into one or more tables or "relations" consisting of columns and rows. Each table has a primary key, which uniquely identifies each row. Relationships between tables are established using foreign keys.

The Structured Query Language (SQL) is the standard programming language used to manage and query data in sqlDBs. SQL allows users to perform operations such as creating tables, inserting data, updating records, deleting data, and retrieving information through complex queries. This structured approach to data management ensures data integrity and consistency through features like ACID (Atomicity, Consistency, Isolation, Durability) compliance.

Popular examples of sqlDBs include MySQL, PostgreSQL, Oracle Database, Microsoft SQL Server, and SQLite. These databases are widely used for a vast range of applications, from small websites to large enterprise systems, due to their reliability, scalability, and maturity. They are particularly well-suited for applications requiring complex transactions and structured data relationships.
