Data sources are an electronic storage unit to which data (information) is transferred, whether manually or automatically. Data transformation takes place when information is received, filtered, converted into the right mode, and delivered to the storage unit. Reporting takes place when the data in the storage unit is transformed into applications for computer users who can access the data via password, security entry code, etc. Metadata, translated actually as "the data about data," represents a library catalog-like database which gives you the breakdown of all the different data in the data storage unit and tells you what each kind of data is about. Operations indicate the processes by which data is stored, cleaned, transformed, and transferred to user applications. Operations incorporate loading, cleaning, and extracting information, user management, security, capacity management, and other relevant actions.
