PowerDesigner OverviewPowerDesigner is a case (computer-aided software Engineering) tool for Sybase that integrates enterprise architecture, UML (Unified Modeling Language), and databases. It can be used not only in the different stages of system design and development (i.e. business analysis, conceptual model design, physical model design and object-oriented development phase), but also in the use of management, system design, development and other related personnel. It is the first modeling so

How does ERP, EAM, and inventory management settle bills? I think there are many friends who have participated in the sales and purchase of enterprise information products. In particular, if you want to customize a system suitable for your Enterprise, you also need to have cl

model mainly describes the data type, content, nature, and connection between data. Data structure is the basis of the data model, and data operations and constraints are built on the data structure. Different data structures have different operations and constraints. 2) Data Operations: Data Operations in the data model mainly describe the operation types and operation methods on the corresponding data structure. 3) Data constraints: Data constraints in a data model mainly describe the syntaxe
