This chapter describes the design specifications for database modeling and application development. Modeling compliant with these specifications fits the distributed processing architecture of GaussDB(DWS) and provides efficient SQL code.
The meaning of "Proposal" and "Notice" in this chapter is as follows:
- Proposal: Design rules. Services compliant with the rules can run efficiently, and those violating the rules may have low performance or logic errors.
- Notice: Details requiring attention during service development. This term identifies SQL behavior that complies with SQL standards but users may have misconceptions about, and default behavior that users may be unaware of in a program.
