The list of best open source and commercial Data Warehousing Tools and Techniques:
In today’s rapid growing computing world, big data & predictive analysis have grown at quite a fast pace. During all this transformation in business intelligence over past few years, the data warehouse has proven to be a continuous and reliable technique in managing integrated data.
Let us first understand what a data warehouse is.
Data warehouse, also known as DWH is a system used for reporting and data analysis. It is considered to be the core of business intelligence (BI) as all the analytical sources revolve around data warehouse.
DWH is a central repository that stores current as well as historical data in one place. It contains integrated data from different sources and is used to prepare analytical reports which further get distributed to knowledge workers in the enterprise. These reports help the organizations to understand/predict their sales patterns and design marketing strategies.
Next question that arises here is- How is data processed in a data warehouse?
This can be well understood by taking reference of the basic architecture of DWH.
All the operational sources place data into a staging area (staging tables/databases/schemas etc.) This data might need to pass through an operational data store that cleanses the data. Data is cleansed in order to ensure data quality before it is used for reporting.
Data warehouses that operate on typical Extract, Transform, Load (ETL) methodology use staging database, integration layers and access layers to carry out their functions. Staging databases store raw data coming from each data source and the integrating layer integrates it.
The integrated data is further arranged into hierarchical structures called dimensions. The cataloged data is made available to managers and professionals for carrying out activities like data mining, market research, and decision support etc.

Now that we have discussed data warehouse in detail, let us move on to another extremely interesting question- Which are most popular data warehouse tools available in the market and how to choose one?
The data warehouse is future of every company. Hence before picking up a final tool, one should make sure that the tool is capable of meeting growth and comprehensive requirements of the organization in present as well as future.
