The Blueprint Beneath the Blueprint: Designing Data Model and Choosing Its Database
The article discusses the importance of designing a data model before creating diagrams in software development. It emphasizes that a data model serves as the system's memory, detailing what information is stored and how it relates. The author argues that understanding the data structure is crucial for effective system design and implementation.
- ▪A data model describes what a system remembers and how stored information relates to one another.
- ▪Creating diagrams without a clear data model can lead to vague and ineffective blueprints.
- ▪The article advocates for using multiple databases to avoid complications as the system grows.
