Business Intelligence Consulting Services: How to Know Data is Lying to You?

In order to save the big data into the data warehouse is not simple thing it require specific sense and attitude regarding the business intelligence tools. Like if there is calculation of the data A and B gives the data value C and now to save this data for future use is important task. There are many state of art Business Intelligence Consulting Services that can be used to save this data.

Data warehouses assemble and store data in an effective way. If we want to make calculations then store data into the data warehouse. While doing this few considerations are:

•  Ratio or percentages should not store it in the fact table. We should calculate it on the fly like in a BI reporting dashboard. In order to enable the users to view that ratio correctly and quickly, at any hierarchy level.
• The aggregation should not be store in the fact table, but should be calculated on the fly. If you store it in a fact table, you will need to “pin” the calculation to an exacting level, so users will not be able to drill up and down the hierarchy to view that aggregate measure.
• To represent aggregation and join use techniques originally from BIandData Warehouse. In Business Intelligence Solutions columns are used by RDMS to save this type data and easily data can be updated/deleted.
  In these days RDBMS technology giving us “computed columns”, that means, for a logic like modulo or subtraction, we can store them as “computed columns”. The database engine will make calculations on these columns on the dashboard, as and when the data is updated/inserted. They are very effective.
• There are many, places within the Data Warehouse Business Intelligence Software where you can “physicalize” a calculation or a business logic like Nova view, QlikView, Tableau or SSAS calculation. There are disadvantages and advantages of each place, so we need to make careful choice.
• Stream component. Like if you put the business logic in a DB view, then both the reports and the cube are able to access it. But if you want to make its report, then the cube will not able to access it.
