Relationships that capture the critical information that the application needs to persist in the database. In logical data modeling, the Database Designer is concerned with identifying the key entities and

Provided in the next two sections of this guideline. Summaries of logical and physical data modeling are A discussion of conceptual data modeling is provided in Concepts Conceptual Data Modeling. These stages ofĭata modeling reflect the different levels of detail in the design of the persistent data storage and retrieval Guideline was developed, the UML 1.4 data-modeling profile was not available.Īre three general stages in the development of a Data Model: conceptual, logical, and physical. Note: The data modeling representations contained in this guideline are based on the UML 1.3. For background information on relational Data Models and Object Models see Concept: Relational Databases and Object Orientation. This guideline describes the model elements of the UML profile for database modeling used to construct a Data Model forĪ relational database. Because there are numerous existing publications on general database theory, it does notĬover this area. Models can also be used to define which system in the enterprise is the "owner" of the data for a specific businessĮntity and what other systems are users of (subscribers to) the data.

Enterprise andĭepartmental level Data Models can be used to provide standard definitions for key business entities (such as customerĪnd employee) that will be used by all applications within a business or a business unit. These types of Data Referential integrity (constraints and triggers), as well as stored procedures used to manage access to the database.ĭata Models might be constructed at the enterprise, departmental, or individual application level. The UML database profile also provides constructs for modeling Model the physical storage layout of the database. The Unified Modeling Language (UML) profile for database design provides databaseĭesigners with a set of modeling elements that can be used to develop the detailed design of tables in the database and Data Models are used to design the structure of the persistent data
