Final answer:
Excel database functions such as DSUM, DAVERAGE, DMAX, DMIN, and DCOUNT allow for conditional calculations based on specified criteria. The DGET function can retrieve specific data entries, while the INDEX function combined with XMATCH provides a method to lookup data. FORMULATEXT is used to display the formula from one cell as text into another cell.
Step-by-step explanation:
How to Use Database Functions in Excel
Working with database functions in Excel allows users to execute conditional calculations. For example, in cell B2, the DSUM function can be used to calculate the total tuition for junior and senior accounting students. The syntax would look something like this:
=DSUM(Students!A1:I42, "Tuition", CriteriaRange)
This formula would be using a criteria range that specifies the conditions 'Junior' and 'Senior' for the 'Year' field, and 'Accounting' for the 'Major' field. Similarly, other functions like DAVERAGE, DMAX, DMIN, and DCOUNT perform average, maximum, minimum, and count calculations under specified criteria, respectively.
Additionally, using the DGET function in cell B9 retrieves the last name of a student whose ID is specified in cell A9. If you wanted to make a column letter absolute in the formula, you would use dollar signs like so:
=DGET(Students!A1:I42, "$G", A8:A9)
where "$G" represents an absolute reference to the column containing last names.
Further, the INDEX function combined with the XMATCH function allows for the lookup of data in a specified array. The FORMULATEXT function is used to display formulas as text in another cell, which is helpful for auditing and documentation purposes.
