In the Oracle ERP method system, the application implementation method belongs to the implementation management category. From the aim process, we can see that the system timeline is divided into six phases: ◆ Definition stage)◆ Operations Analysis)◆ Solution design)◆ Build)◆ Transition)◆ Production stage) Note: The legend is from the official aim 3.1.0 documentation.The implementation of information systems takes precedence over planning, while plann

. Snapshots allow you to maintain copies of remote data locally, but these copies are read-only. To modify a local copy, you must use the advanced copy function. When you want to extract data from a table or view, you can extract data from the snapshot. 1. Specific snapshot Structure Snapshots are widely used and can be used for performance optimization and

management system. Data insertion, modification, and retrieval must be performed through the database management system. The Data Administrator is responsible for creating, monitoring, and maintaining the entire database so that the data can be effectively used by anyone with the right to use it. The database administrator is generally a person with high busines
