Essential Calculate + Essential XlsIO
Essential Calculate lets you add calculation support to objects by implementing an interface, ICalcData. CalcQuick and CalcDataGrid both implement ICalcData which gives them their calculation support. ICalcData is designed around a rectangular array of data. But you can hide this rectangular design as CalcQuick does.
Here is one simple application of this concept. Say you use Excel to design a workbook with series of spreadsheets that calculate some values based on some inputs. For example, using inputs like age, sex, state and car model, you may have a workbook that does a series of lookups and then produces what car insurance may cost this individual. You could use Essential Calculate + Essential XlsIO to read this workbook, accept a series of inputs, and output a series of results all on a machine that does not host Excel.
