Powerdesigner function introduction
Conceptual data model
CDM executes the complete logical structure of the database, independent of any software or data storage structure. Conceptual models often contain data objects that are not yet implemented in the physical database. This provides form data for running plans or business activities.
The conceptual data model is the end-user’s view of data storage and reflects the user’s comprehensive information needs.
It has nothing to do with physical implementation details, only the relationship between entities is considered.
CDM is a tool suitable for the system analysis stage.
Entity data model
PDM physical implementation of narrative database. With PDM, you can take into account the details of the actual physical implementation. This is within the two software or data storage structures in the account. You can modify PDM to suit your performance and physical limitations.
The main goal is to use the real-world model established in CDM to generate specific DBMS scripts, store the information storage structure in the database, and ensure the integrity and consistency of the data in the database.
PDM is a tool suitable for the system design phase.
OO mode.
OOM is an OOM, which contains a series of packages, classes, interfaces and the relationships between them. Combined, these objects form the class structure of the design view of all (or part of) the software system logic. OOM is essentially a static conceptual model of a software system.
You create an object-oriented model using the PowerDesigner Object-Oriented Model. (OOM) You can create an OOM for purely object-oriented prototyping purposes, generating Java files or PowerBuilder files, or you can use Physical Data Model (PDM) objects in the OOM to represent relational database design analysis.
Business plan model
The BPM model (BPM) describes the tasks and internal processes inherent to various enterprises, and how customers interact with each other in these tasks and processes. BPM is a conceptual model that looks at business logic and rules from the perspective of business partners. It uses a diagram to describe the interaction between procedures, processes, information, and cooperation agreements.
powerdesigner software advantages

2. Physical data model
The Physical Data Model (PDM) describes the physical completion of database queries and is suitable for system software design.
3. Object-oriented model
The object-oriented model (OOM) consists of a series of packages, classes, sockets, and their relationships.
4. Business process model
A business process model (BPM) is a definition model that views business logic and standards from the perspective of business partners.
