Data Analysis Expressions (DAX) is the native formula and query language for Microsoft PowerPivot, Power BI Desktop and SQL Server Analysis Services (SSAS) Tabular models. DAX includes some of the functions that are used in Excel formulas with additional functions that are designed to work with relational data and perform dynamic aggregation.
Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).
SQL includes operators and functions for calculating values on stored values. SQL allows the use of expressions in the select list to project data, as in the following example, which returns a list of books that cost more than 100.00 with an additional sales_tax column containing a sales tax figure calculated at 6% of the price.

SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
Extending this to get the anchor day, the procedure is often described as accumulating a running total T in six steps, as follows: Let T be the year's last two digits. If T is odd, add 11. Now let T = T / 2 . If T is odd, add 11. Now let T = 7 − (T mod 7). Count forward T days from the century's anchor day to get the year's anchor day.
Date windowing is a method by which dates with two-digit years are converted to and from dates with four-digit years. [1] The year at which the century changes is called the pivot year of the date window. [2] Date windowing was one of several techniques used to resolve the year 2000 problem in legacy computer systems. [3]
