Models like ERDs are used to represent a high level conceptual overview of a system, or to as a lower level specification that can drive the implementation of the database.
|
|
|
|
** Conceptual
|
|
|
|
- Abstract/big-picture
|
|
- Useful in inital design stages and for communication
|
|
|
|
** Implementation
|
|
|
|
- Concrete/detailed
|
|
- Useful in documenting and specifying structure (for devs etc)
|
|
- Should be detailed and specific enough to allow a dev to implement it without having to guess at details
|
|
- Should be tailored to the specific implementation technologies or systems
