Data Warehousing Lifecycle:-

ETL - Extract, Transform and Load
Expedien places a strong emphasis on data acquisition processes. This includes sourcing, cleansing, transforming, and aggregating data using parallel technology tools to build industrial-strength ETL processes that accommodate high data volumes from disparate sources. We identify the best sources for data elements, reconstruct data when required and deploy the most appropriate tools to retrieve the data from its primary sources. Through the cleansing process, we enhance data quality by not only ensuring data accuracy, type, and consistency, but also by eliminating duplicate records.

Data Repositories
Expedien is experienced at building a variety of data repositories, including operational data stores, data marts, data warehouses, web warehouses, and data hubs. We start by implementing and properly documenting a physical data model while at the same time ensuring that data from all functional areas is sufficiently integrated to support cross-functional analyses. We also perform databases tuning, model de-normalization, and aggregation, as necessary, to support information delivery specifications. When scalability requirements call for it, we partition and distribute data into a parallel architecture.

Data Warehousing Management
As the data warehouse grows, management of the repository is a crucial step in optimizing results and return on investment. We provide data warehousing administration services such as performance analysis, user analysis, benchmarking, auditing, and tuning to help clients measure the ongoing success of their data strategies.
