For example, the changing of bits from one format to another, usually for the purpose of application interoperability or of the capability of using new features, is merely a data conversion. Data conversions may be as simple as the conversion of a text file from one character encoding system to another; or more complex, such as the conversion ...
Data integration, by contrast, is a permanent part of the IT architecture, and is responsible for the way data flows between the various applications and data stores—and is a process rather than a project activity. Standard ETL technologies designed to supply data from operational systems to data warehouses would fit within the latter ...
In computing, data transformation is the process of converting data from one format or structure into another format or structure. It is a fundamental aspect of most data integration [1] and data management tasks such as data wrangling, data warehousing, data integration and application integration.
For example, if the source system lists FirstName but the destination lists PersonGivenName, the mappings will still be made if these data elements are listed as synonyms in the metadata registry. Semantic mapping is only able to discover exact matches between columns of data and will not discover any transformation logic or exceptions between ...
Data cleansing: The removal of errors within a dataset; Data merging: The bringing together of multiple datasets into a common framework – conflation is a good example of this; Data verification: The comparison of multiple datasets for verification and quality assurance purposes; Data conversion: Conversion between different data formats.
When the plan is made and everyone knows what is expected from them, the technical changeover can start. First the old data needs to be converted into a form which is able to work with the data in the new system (Koop, Rooimans and de Theye, 2003). Then this data needs to be loaded into the new system, which results in the so-called loaded data.

Plan that facilitates in reversing the direction of the replication in order to go back to the old system without loss in data or information. (Microsoft, 2004) Test conversion Segmental test conversion, before the actual conversion takes place with as goal to be better prepared against uncertainties or problems in the actual conversion process.
