Analyzing and Manipulating Numeric Business Data: An Aid to Non-Expert Users (Spreadsheet Programs)
In DSS, we need 'data manipulation' facilities which can satisfy the requirements of data transformation, and data restructuring or reconstruction. For this, we focused on the tabular form (TF) and found that the syntactic structure of the TF is closely related with the structure of data it …
