The following is based on AX 2012, but the content is still relevant in Operations:

• Intrinsic Functions [AX 2012] (https://msdn.microsoft.com/en-us/library/aa626893.aspx)

This link goes a little beyond what we have done in this chapter, but has some very useful information about types.

• X++ variables and data types (https://ax.help.dynamics.com/en/wiki/xpp-variables-and-data-types/)

The following link focusses on modelling aggregate data, but also includes important information about Non-Clustered Column Store Indexes (NCCI), which are in memory indexes used for analysing aggregate data.
