PowerDesiger
PowerDesiger is a Enterprise users can create new applications to existing business applications or software reverse engineering, and the entire process will be very quick, smooth and economical. The problems that beset the project development -------- using different techniques, cross-platform operation, and in most enterprises to develop a common voice can be mixed more readily solved. So that the user can at all stages in the development process (from system analysis and design to automatically generate code) to focus on achieving business needs.

the role of structural characteristics of an effective composition of visual symbolic information on the role of visual symbols PowerDesiger for all types of data model provides a visual symbol that not only allows designers to more easily and more quickly to non- Computer professionals demonstrate the database design and application design, system designers and operational staff using the system easier to understand and communicate with each other, as well as communication within the project group is more intuitive, accurate and easier to coordinate work to accelerate system design and development process. Effective management structure PowerDesiger to provide users with access to project information and effective structure. Designers can not only use it to design and create all kinds of data models and the model can be integrated out a detailed document, or a database generated from the established physical model, and then generate the required documentation. Developers can also use a variety of current popular application development tools to quickly generate the application objects and components to further modify and improve to better meet the application requirements. This approach strengthened the control of the application development process, improve software productivity. PowerDesiger flexible and integrated features, the structure of its integrated development team members not only can reduce them, but also the developer of its projects according to size, scope and budget and other aspects of the factors to select the desired modules, but also facilitate the further expansion of the system. PowerDesiger is the most popular features of the software analysis and design tools, which generally has the following characteristics: ► To provide a complete set of all IT systems analysis and design for fully integrated modeling solution, one of the few in an environment designed to support a variety of modeling tools: database modeling (conceptual data model CDM, physical data model PDM), business process data model for BPM, object-oriented model of OOM, and the free model of FEM. ► data modeling: the use of a reliable method based on the true levels (conceptual and physical) relational database modeling, design and build the database schema. Also supports data warehouse modeling techniques in particular. ► powerful text block automatically generate custom function (RTF and HTML formats), the programmer from a large number of text block duplication freed (such as the generation large-scale database data dictionary, etc.). ► Users can fully customize the meta-model board (including the DBMS definition file, object-oriented language definition file, etc.), extended attributes, etc. for the specific needs of the specific needs of user-generated code provides the maximum possibility. ► results-oriented, data-centric business process model (BPM) enables business and IT staff in the design and development of the successful cooperation, creativity and business needs help to make up for IT system development gap between creative, to ensure that projects meet business goals. ► provides all UML diagrams and full support for all major platforms (compatible with J2EE (TM), ebXML, Web Services and NET, etc.) ► a single repository-based environment provides a variety of modeling techniques for metadata integration , including technical and non-technical aspects (such as objects used in the design, relationship mapping and the use of links and synchronization of any changes within a model to convey to all other models). ► objects for all models and provides a common performance, extended attributes,
paul smith uk, and scripting, not just the database and the development of custom language support. ► into the full version control (Repository), used to store and manage all modeling and design process information, analysis and design and version control will be seamlessly integrated, making the modeling team collaboration to be more effective management and control, and minimize some of which are inconsistent, you can easily access and share all the members of the Working Group on the modeling and information, the repository can be upgraded to support the role of security settings, version control, search and reporting capabilities, thereby greatly enhancing the development of by efficiency. PowerDesigner composition database model as a graphical design tools, and its integrated features flexible, modular design to a total of six modules of the following components: (1) ProcessAnalyst: the demand for system analysis, design and construction can be used for data flow diagrams (DFD) and data dictionary. It supports multiple process modeling methods, the user can choose their own application environment modeling method to describe the system's data and data processing. (2) DataArchitect: the concept for the interactive layer and physical layer design and construction of the database. DataArchitect can easily use the design concept of the database model and physical model of the DBMS automatically generated. The module also offers the ability to generate high-quality documentation and reverse engineering capabilities, you can get from the existing database and its physical model and conceptual model, and generate the appropriate documentation. (3) AppModeler: application modeling tools for physical modeling and component application objects and data generation. (4) MetaWorks: for team development, information sharing and model management. (5) WarehouseArchitect: data warehousing and data sets for the modeling and implementation. (6) Viewer: used to read-only access to the graphical model information across the enterprise. Information PowerDesiger powerful database modeling capabilities, including conceptual data model (CDM) and physical data model (PDM) in two parts. The concept of independence and DBMS data model, can be seen as an abstract understanding of the real world, you can create a conceptual data model does not consider the final choice of the DBMS, from the physical implementation considerations. The physical data model (PDM) is the physical implementation of data model is needed, and Microsoft SQL Server, Qracle DBMS such as dealing with the specific model. Thus, PDM is more specific than the CDM, details, and associated with the database. PDM generated from the CDM is a reverse engineering, so need to change on the physical level the concept of level of the model be modified accordingly. PDM and CDM in the correspondence between the objects the following table: PDM CDM objects in the object table (Table) entity (Entity) column in the table (Table column) physical attributes (Entity attribute) outside the main code or code ( Primary or Foreign key) identifier reference (Reference) to many relationship connection table (Join table) CDM-many links to the application of the following specific examples of CDM: The concept of information system design tool, that entity - relationship graph (ER Figure), CDM is in its own way to describe ER diagram. At this point do not consider the physical implementation details, saying only that the overall logical structure of the database, independent of any software and data storage structure. Staff and projects such as the following ER diagram of two entities: the study by PowerDesinger so I can use this new data analysis and modeling tools for system analysis and design of the whole, to become an excellent systems analyst to lay a solid foundation.
