2. Schema migration - Wikipedia

   en.wikipedia.org/wiki/Schema_migration

   Most schema migration tools aim to minimize the impact of schema changes on any existing data in the database. Despite this, preservation of data in general is not guaranteed because schema changes such as the deletion of a database column can destroy data (i.e. all values stored under that column for all rows in that table are deleted ...

3. Schema crosswalk - Wikipedia

   en.wikipedia.org/wiki/Schema_crosswalk

   Crosswalk tables are often employed within or in parallel to enterprise systems, especially when multiple systems are interfaced or when the system includes legacy system data. In the context of Interfaces, they function as an internal extract, transform, load (ETL) mechanism. For example, this is a metadata crosswalk from MARC standards to ...

4. Data migration - Wikipedia

   en.wikipedia.org/wiki/Data_migration

   Data migration is a project through which data will be moved or copied from one environment to another, and removed or decommissioned in the source. During the migration (which can take place over months or even years), data can flow in multiple directions, and there may be multiple simultaneous migrations.

5. Data mapping - Wikipedia

   en.wikipedia.org/wiki/Data_mapping

   In computing and data management, data mapping is the process of creating data element mappings between two distinct data models. Data mapping is used as a first step for a wide variety of data integration tasks, including: [1] Data transformation or data mediation between a data source and a destination

6. Data transformation (computing) - Wikipedia

   en.wikipedia.org/wiki/Data_transformation...

   Typically, the data transformation technologies generate this code [5] based on the definitions or metadata defined by the developers. Code execution is the step whereby the generated code is executed against the data to create the desired output. The executed code may be tightly integrated into the transformation tool, or it may require ...

7. Process-data diagram - Wikipedia

   en.wikipedia.org/wiki/Process-data_diagram

   Since project management is actually not within the scope of this research, the concept CONTROL MANAGEMENT has not been expanded. However, in a complex project is RISK MANAGEMENT of great importance. Therefore, the choice is made to expand the RISK MANAGEMENT concept. Figure 10: Example Process-Data Diagram - Orientation phase in a complex project

8. Data management plan - Wikipedia

   en.wikipedia.org/wiki/Data_management_plan

   A data management plan or DMP is a formal document that outlines how data are to be handled both during a research project, and after the project is completed. [1] The goal of a data management plan is to consider the many aspects of data management, metadata generation, data preservation, and analysis before the project begins; [2] this may lead to data being well-managed in the present ...

9. Data-flow diagram - Wikipedia

   en.wikipedia.org/wiki/Data-flow_diagram

   When using UML, the activity diagram typically takes over the role of the data-flow diagram. A special form of data-flow plan is a site-oriented data-flow plan. Data-flow diagrams can be regarded as inverted Petri nets, because places in such networks correspond to the semantics of data memories. Analogously, the semantics of transitions from ...
