Understanding Primary Key vs Foreign Key in Tally

In Tally, a primary key and a foreign key are two important concepts related to database management. Let's delve into the differences between the two:

Primary Key in Tally:

A primary key in Tally is a unique identifier for each record in a table. It ensures that each record is distinct and serves as a reference point for other tables. The primary key is used to enforce entity integrity and prevent duplicate entries in the table.

Foreign Key in Tally:

On the other hand, a foreign key in Tally is a field in a table that is a primary key in another table. It establishes a relationship between the tables by referencing the primary key of another table. Foreign keys help maintain referential integrity and ensure data consistency across related tables.

In summary, the primary key uniquely identifies each record in a table, while the foreign key establishes a link between tables by referencing the primary key of another table.

Understanding the distinction between primary keys and foreign keys is crucial for efficient database management in Tally.
