ILM is a high-level information flow model, mainly used for data replication between distributed databases.įrom the business layer, application layer and technical layer to the full description of the enterprise architecture. It uses a diagram to describe the interaction between procedures, processes, information, and cooperation agreements. BPM is a conceptual model of business logic and rules from the perspective of business partners.

OOM is essentially a static conceptual model of a software system.īPM describes the various internal tasks and internal processes of the business, and how customers influence each other with these tasks and processes. Generate the database from the physical data model, or reverse engineer the database to obtain the physical data model.Ĭontains all the common UML graphics: class diagram, object diagram, package diagram, use case diagram, sequence diagram, collaboration diagram, interaction diagram, activity diagram, state diagram, component diagram, composite structure diagram, deployment diagram (configuration diagram). The logical model is not necessary in the whole step, and the physical model can be generated directly through the conceptual model.īased on a specific DBMS, design on the basis of conceptual data model and logical data model. The logical model can be used to generate a physical model for a specific database management system. The logical model is mainly to make the whole conceptual model easier to understand, and at the same time does not depend on the specific database implementation. The many-to-many relationship in the conceptual model will be realized in the logical model by increasing the one-to-many relationship of intermediate entities. The logical model is between the conceptual model and the physical model, and has the characteristics of the physical model. Specifically, on the one hand, the logical model displays entities, their attributes, and the relationships between entities on the other hand, inheritance, references in entity relationships, etc. The logical model is an extension of the conceptual model, representing the logical sequence between concepts, and is a model belonging to the method level. Model data and information, organize data in the form of entity-relation diagram (ER diagram), and test the validity and rationality of data design. PowerDesigner is mainly divided into 7 types of modeling files: It started with database modeling and later developed into a comprehensive case tool. Rose is a modeling tool that specializes in UML object models, and then developed to database modeling, while PowerDesigner is just the opposite.
PowerDesigner is a very powerful modeling tool software, comparable to Rose, and it is also one of the most famous modeling software today.
