Abstract
A method of managing non-persistent data in a persistent database includes adding the non-persistent data to the database in the form of a temporary entry. The temporary entry can be a temporary row or column, a temporary table or a temporary database with temporary tables. The method also includes tracking the non-persistent data in order to maintain the original state of the persistent database. A column of temporary bits is added to track the rows, and the temporary columns are tracked via a bit in the schema. Non-persistent temporary entries can be added to any relational database to manipulate data while maintaining the original state of the database. Using temporary entries is advantageous when a large amount of data already exists in a database and a user needs to enhance and/or manipulate the data while still retaining the original state of the data.
