Explain the example. Mostly, formula issues. But also incorrect values. It is also necessary a lot of work to add a new year or category. After adding data, it may be necessary to update the formulas.
Our solution it to have a specification of the spreadsheet one wants and make the spreadsheet follow it. It helps the user to keep the data correct as only the input cells are allowed to be changed. The formula are automatically updated in whenever necessary. To add a new year or category just press one button
No they don&apos;t!! We infer them from data instances, using data mining techniques. A relational model is computed, and from that a ClassSheet is obtained.
Change the model to an evolved one. You can edit the model and have the data automatically co-evolved.
You can also evolve the data and have a new model for it. Why? Because it is probably more natural for some people. Also, because some operations are also easier to do on the data than on the model.
You can Query it!!
Begin query construction End query construction
Spreadsheet tend to have errors We have devised a model-driven approach to help users Models can automatically be inferred And guide the user in introducing correct data We have empirical evidence that our system indeed helps users to be more efficient and effective
