In older version of Microsoft Dynamics AX , there is no option to use concept of ‘Column Store’.But in Microsoft Dynamics 365 Finance & Operations you can set the “IndexType” property of a index in a table.There are 2 values available – 1) Index 2)ColumnStore.
A columnstore index stores data in a column-wise or in columnar format where as index stores data in a row -wise format.
Columnstore index is to reduce I/O, which can have a direct impact on query performance as comparison to index.
Columnstore is designed to speed up data-warehouse queries & read-Only operations.
Columnstore is better for OLAP whereas index is better for OLTP.
