   The result of this is that complex interfaces are required between systems that share data. These interfaces can account for between 25 and 70% of the cost of current systems. Required interfaces should be considered inherently while designing a data model, as a data model on its own would not be usable without interfaces within different systems.

   en.wikipedia.org/wiki/Web_data_integration

   Web data integration (WDI) is the process of aggregating and managing data from different websites into a single, homogeneous workflow. This process includes data access, transformation, mapping, quality assurance and fusion of data. Data that is sourced and structured from websites is referred to as "web data".

   Data integration refers to the process of combining, sharing, or synchronizing data from multiple sources to provide users with a unified view. [1] There are a wide range of possible applications for data integration, from commercial (such as when a business merges multiple databases) to scientific (combining research data from different bioinformatics repositories).

   Users can utilize erwin Data Modeler as a way to take conceptual data model and create a logical data model that is not dependent on a specific database technology. [28] This schematic model can be used to create the physical data model. Users can then forward engineer the data definition language required to instantiate the schema for a range ...

   Web engineering focuses on the methodologies, techniques, and tools that are the foundation of Web application development and which support their design, development, evolution, and evaluation. Web application development has certain characteristics that make it different from traditional software, information systems, or computer application ...

7. Virtual engineering - Wikipedia

   en.wikipedia.org/wiki/Virtual_engineering

   When an engineer takes hold of a virtual component and moves or alters it, he or she should only have to think about the consequences of such a move in the component's real world counterpart. Engineers must also be able to create a picture of the system, the various parts of the system, and how the parts will interact with each other.
