A list of the best open source and commercial Data Warehousing Tools and Techniques:
In today's rapidly growing computing world, big data & predictive analysis have grown at a quite faster pace.
During all this transformation in business intelligence over the past few years, the data warehouse has proven to be a continuous and reliable technique in managing the integrated data.
What is a Data Warehouse?
Data warehouse, also known as DWH is a system that is used for reporting and data analysis. It is considered to be the core of business intelligence (BI) as all the analytical sources revolve around the data warehouse.
DWH is a central repository that stores current as well as historical data at one place. It contains integrated data from different sources and is used to prepare analytical reports which further get distributed to the knowledge workers in the enterprise.
These reports help the organizations to understand/predict their sales patterns and design the marketing strategies accordingly.
How is Data processed in a Data Warehouse?
This can be well understood by taking the 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 would cleanse the data. Data is cleansed in order to ensure the 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 the managers and professionals for carrying out activities like data mining, market research, and decision support.
So far we have discussed data warehouse in detail, let us now move on to another extremely interesting question
