Data migration is the process ... While the specifics of a data migration plan may vary—sometimes ... Examples of such migration drivers are mergers and ...
Data conversion is the conversion of computer data from one format to another. Throughout a computer environment, data is encoded in a variety of ways. For example, computer hardware is built on the basis of certain standards, which requires that data contains, for example, parity bit checks.
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 ...
Batch data transformation is the cornerstone of virtually all data integration technologies such as data warehousing, data migration and application integration. [ 1 ] When data must be transformed and delivered with low latency, the term "microbatch" is often used. [ 6 ]
Bitstream copying (or data backup) is a foundational operation often employed before many other practices, and facilitates establishing the redundancy of multiple storage locations: refreshing is the transportation of unchanging data, frequently between identical or functionally similar storage formats, while migration converts the format or ...
The size of the data to be migrated makes the very resource-intensive (Source- Destination- Temporary- storage, network bandwidth, etc.), which means that auditing the migration process could also be complex and require consistency and traceability. Another common issue in content migration is the loss of SEO and page rank in search engines.
Migration can be from a mainframe computer which has a closed architecture, to an open system which employ x86 servers. As well, migration can be from an open system to a Cloud Computing platform. The motivation for this can be the cost savings. [1] Migration can be simplified by tools that can automatically convert data from one form to another.
Data extraction is the act or process of retrieving data out of (usually unstructured or poorly structured) data sources for further data processing or data storage (data migration). The import into the intermediate extracting system is thus usually followed by data transformation and possibly the addition of metadata prior to export to another ...
