For instance, the new application might use another database vendor and most likely a very different database schema.

PDF does not know of a word space character—the space ...
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 ...
Examples of such languages include: AWK - one of the oldest and popular textual data transformation language; Perl - a high-level language with both procedural and object-oriented syntax capable of powerful operations on binary or text data. Template languages - specialized to transform data into documents (see also template processor);

This can be accomplished by using a custom program, an integrated proprietary "mapper" or an integrated standards-based graphical "mapper," using a standard data ...

The data can be sliced by removing all customers except for a group under study, and then diced by grouping by product. A dimensional data element is similar to a categorical variable in statistics.
