Description: System tables are fundamental structures in relational databases that store metadata and system information about the database. These tables contain crucial data that describe the structure, relationships, and properties of objects within the database, such as tables, indexes, views, and users. Through these tables, database administrators can obtain information about performance, configuration, and system integrity. System tables are essential for database management and maintenance, as they allow for audits, query optimization, and data security assurance. Additionally, they provide a framework for interaction between the database management system (DBMS) and users, facilitating the management of permissions and roles. In summary, system tables are an integral part of the database architecture, offering a detailed and structured view of its internal workings and enabling efficient and effective management of data resources.
