Being able to quickly and easily access data is important, but it is not always easy to maintain data integrity, especially when it comes to databases. This guide will provide developers with valuable and relevant information about how to prevent accidental or malicious deletion of rows from a view in Markdown Format.
What is A View?
A view is essentially a virtual table composed of data from one or more tables. Views enable the user to present data from many individual tables in an organized format. This increases the performance of the database since it eliminates the need to create complex queries and ensures data integrity. Views also provide an easy way to update data in all associated tables with a single statement.
How to Prevent Deletion of Rows From a View
- Create a view trigger. This will be a database statement that is triggered when someone attempts to delete data from the view. The view trigger will be invoked and a request for confirmation of the delete action will be displayed.
- Enforce row-level security. This entails restricting access to certain data based on a user’s permissions or other security criteria. This will help to ensure that only authorized users have access to data and can prevent malicious or accidental deletion of rows from the view.
- Implement database auditing. Database auditing keeps track of changes to the database and can serve as a valuable tool in preventing malicious or accidental deletion of rows from a view. Auditing records will record any changes to the database and can help to identify and prevent tampering with data.
