Abstract

Embodiments of the present invention provide a method and system for managing data for performing write back on what-if analysis.In an embodiment,the method of the present invention stores only minimal data during write back on what-if analysis and actual calculations are deferred to the time when data is actually queried by a user. The present invention comprises a write back processor which stores all the modifications to the original data in a write back database. When the original database is queried by user,the write back processor calculates the changes to the queried data based on the modifications and provides the report.

Description

technical field [0001] The present invention generally relates to the field of database technology. In particular, the present invention relates to a method and system for managing multiple versions of data while performing what-if analysis. Background technique [0002] What-if analysis is a business intelligence technique in which business people can simulate business changes based on some given assumptions or scenarios and view the results of the changes. When changing existing data, what-if analysis automatically changes other affected values ​​in the report. What-if analysis can be used in a variety of areas including, but not limited to, budgetary processes such as future tax rates, interest rates, inflation rates, headcount numbers, and expenses. [0003] figure 1 A traditional approach to write-back for what-if analysis is shown. The method involves a business user using a what-if report to simulate a business change by editing the values ​​of some cells in the r...
