Ques:- Describe the properties of a relational table?
Asked In :-
Target Integration, Yudiz Solutions, Helical It Solutions, Gem Software Solutions, Vinove Software and Services, Visier, Kriti, VCNR Technologies (India), RCKR Software, aspire systems,
Right Answer:
A relational table has the following properties:
1. **Rows and Columns**: Data is organized in rows (records) and columns (attributes).
2. **Unique Rows**: Each row must be unique, often identified by a primary key.
3. **Atomic Values**: Each cell contains atomic (indivisible) values.
4. **Consistent Data Types**: Each column has a specific data type, and all values in that column must conform to it.
5. **Order Independence**: The order of rows and columns does not affect the data's meaning.
6. **Foreign Keys**: Relationships between tables are established using foreign keys.
