Best practice for storing data

Hi George,

Thank you for the forum question.

Excel is a great application to store large data sets if you do not store the data in the worksheets but in the Excel data model. Microsoft has created an amazing compression technology which outperform most databases.

You can have 2,147,483,647 tables in this "Database" and each of those tables can have a maximum of 2,147,483,647 columns and 1,999,999,997 rows.

You can have live connections to any number of data sources and Microsoft has created a very powerful query/function language called DAX (Data analysis expressions), which can perform cube calculations very fast.

All the Power tools in Excel are created to handle large data sets. PowerPivot, Power Query, Power View, and the stand alone application Power Bi.
