Data Warehouse Management Tools

Data Warehouse Management Tools are software applications that extract and transform data from operational systems and loads it into the data warehouse.

The area of data warehouse management is very complex as data captured from operational data sources such as those data coming from transactional business software solutions like Supply Chain Management (SCM), Point of Sale, Customer Serving Software and Enterprise Resource Planning (ERP) and management software to undergo the ETL (extract, transform, load) process.

To facilitate data around the data warehouse, efficient ETL tools should be employed. Companies may either want to buy third party tools or develop their own ETL tools by assigning their in-house programmers to do the job. In general, the rule of thumb is that the more complex the data transformation requirements are, the more advantageous it is to just purchase third party ETL tools.

When deciding to buy a commercial data warehouse management tool, it is always good to consider the following aspects:

Functional capability – This means that the function to be considered is the way the tool handles both the "transformation" piece and the "cleansing" piece. When the tool has strong capability for both the "transformation" piece and the "cleansing" piece, then by all means buy it because in general, a typical data warehouse management tool can only have strong capability.

Ability to read directly from your data source – As mentioned earlier, data warehouse gets its data from various data sources and the ability to read directly from your data source make processing faster and more efficient.

Metadata support – A data warehouse management tool should be able to handle metadata, which is a very important aspect of data warehousing as metadata is used to map source data to its destination.
