SQL Data Dictionary is an application or website that helps users to understand the structure of their databases and the relationships among the different tables and columns. It provides a comprehensive list of all tables, columns and data types in a database, along with detailed descriptions of each item. It also shows the foreign key relationships between tables, allowing users to quickly identify the tables and columns needed to join different tables. Additionally, SQL Data Dictionary can provide useful information about the constraints and indexes associated with the database. This information can help users create more efficient queries, as well as debug their queries when needed.
