How many database functions does excel use to evaluate numeric data in a table?

No, it has far less than that. It has 12 specialised database functions. They are DAVERAGE, DCOUNT, DCOUNTA, DGET, DMAX, DMIN, DPRODUCT, DSTDEV, DSTDEVP, DSUM, DVAR and DVARP. In addition, it would be possible to use many other functions to manipulate data in a database. Even the total amount of functions in Excel is much less than 1000 functions.
