How do I implement versioning in my database schema?
Implementing versioning in a database schema can be done using several strategies. One common approach is to add a version column to your tables. This column can be incremented each time a record is updated.
What are the benefits of using versioning?
Versioning helps in tracking changes over time, allows for easier rollbacks, and can improve data integrity by preventing conflicts.
Are there any downsides to versioning?
Yes, versioning can increase complexity in your queries and may require additional storage space for historical data.
Can you give an example of a versioned table?
Sure! A versioned table might look like this: CREATE TABLE users (id INT, name VARCHAR(100), version INT);
Each time a user is updated, you would increment the version number.
