Data Acquisition

Data Acquisition - Data acquisition includes extracting and filtering data from operational and/or legacy systems, consolidating (merging separate and/or disparate tables into one master table); scrubbing the resulting data (restructuring records, translating field values to a common data dictionary, and checking data integrity inconsistency); transforming the data (adding time stamps, dates, summarizing data, and deriving new fields); and loading the "clean" data into the warehouse database, as well as updating any warehouse indexes.
