We have developed a template specification language that allows the definition of spreadsheet templates that describe possible spreadsheet evolutions. This is important because different target users are assumed to be more or less familiarity with spreadsheets, or with logic. Another problem with spreadsheets is their limitations in terms of the expressive power of their programming paradigm. It extends all traditional methods for interacting with the spreadsheet to the new deductive features, in particular as far as formula manipulation is concerned. Again, this increases the possibility for errors, and makes the spreadsheet difficult to maintain. Observe from the above examples that the spreadsheet metaphor was used to create the rules without the user having to specify any expression with variables. Twenty names were then selected at random from the spreadsheet information. This is clearly an error-prone property of such spreadsheet applications. In effect, typed object instances normally appear in spreadsheets as rows within tables. How this combination of features affects spreadsheet programming warrants some discussion. To add relational information to a spreadsheet, we need to add a lifting formula that expresses how the table information corresponds to logic assertions. When creating a spreadsheet, business rules end up being encoded in spreadsheet formulas. This approach permits the user to retain their investment in their favourite spreadsheet, but asks them to learn additional rules and techniques. Rules can be entered within the context of the spreadsheet itself, which is a powerful advantage. These examples are from corpora and from sources on the web.
