This CBT Nugget explains essential database concepts and terms such as table, view, index, and stored procedure. The video shows how these objects work and interact with each other in a database. It also demonstrates how to create them and use them in a practical setting using SQL Server Management Studio.
Sure, here are the key facts extracted from the provided text:
1. A database contains objects such as tables, views, indexes, and stored procedures.
2. Tables are used to store data and consist of rows (records) and columns (attributes).
3. Tables have a primary key to uniquely identify records within the table.
4. Foreign keys establish relationships between tables, ensuring data integrity and enforcing referential integrity.
5. Views act as a data access layer, providing specific columns and records to users without direct access to the underlying tables.
6. Indexes are used to quickly retrieve data from columns, similar to an index in a book.
7. Stored procedures are executable programs within a database, allowing parameterization for dynamic results.
8. Examples of database objects include tables (e.g., characters, planets), views (e.g., people planets), and indexes on specific columns.
