n-dimensional spreadsheet with a logical data model (including hierarchies) rather than rows and columns:
Net Worth := Assets - Liabilities
- dfee 8y ago> Conventional spreadsheets used on-screen cells to store all data, formulas, and notes. Improv separated these concepts and used the cells only for input and output data. Formulas, macros and other objects existed outside the cells, to simplify editing and reduce errors. Improv used named ranges for all formulas, as opposed to cell addresses. Amazing.

- julienmarie 8y agoQuantrix Modeler is a successor of Improv. I personally love it, but pricing is quite steep.
- spitfire 8y agoQuantrix modeler is actually the successor to Quantrix for nextstep. Quantrix was a contemporary of Improv. Not sure I remember which came first. But Quantrix was the better of the two. I'm collecting a pile of "good ideas"... Someday I'll do something with it.

- greggyb 8y agoThe concepts are there in Microsoft's SSAS, which also lives in Excel as Power Pivot (only the Tabular engine, not the Multidimensional).
