PowerDesigner 12.5 Functional Features

[Abstract]The new PowerDesigner launches a model diagram for building the cube, while object-oriented modeling supports the UML 2.0 standard. But if PDM is to change the database through the forward engineering, it must adjust the syntax for different brand, PowerDesigner support Oracle, DB2, SQL Server, Sybase, Teradata, MySQL and other brand database, if we differentiate the old and new versions, There are about 60 relational databases supported by PowerDesigner.
[Key word] Cube; 　　PowerDesigner; The new PowerDesigner launches a model diagram for building the cube, while object-oriented modeling supports the UML 2.0 standard. As the product features more and more yuan, it is somewhat complicated.

PowerDesigner, who started with data modeling, is now entering 12.5, the main function is divided into the general user-provided process Design module BPM (Business process Model), database modeling e-R Model (Entity-relationship model, Entity-relational module), and UML modeling diagram of software modeling.

These model diagrams are managed by a centrally managed repository (Repository) to further control the version and access rights of the content. In addition, due to the need to import CMMI Requirements Management, PowerDesigner new requirements Management module, can be imported into the requirements analysis files, facilitate follow-up development phase tracking and management.

Provides a visual process presentation tool

For the general users without it background, these model diagrams, such as E-R models and UML, are still difficult to understand, although they present graphical information. It projects need a more understandable graphical presentation tool to clearly illustrate the workings of the system in the face of a generic user, and PowerDesigner's new BPM design tool is designed to reduce the communication barriers caused by professional terminology and symbols.

PowerDesigner's BPM module actually wants to implement the spirit of similar workflow or BPM products, by graphical means, from the start, the program (process), the Judgment (Decision) to the end, to describe the system in the execution of leave, The process of making a system function such as a single or processes.

PowerDesigner supports a number of open process standards, and designers simply click on the desired process language when adding BPM modules, such as BPMN, EbXML Bpss, and BPEL4WS, developed by Microsoft, IBM, Oracle, and Bea, You can apply a standard format design flowchart.

Differences between different process languages, we can discover the different structure when PowerBuilder produce XML description files. If the enterprise does not need to follow the standard, merely draws the flow chart, applies the preset "analysis" as the process language; the designer can also import custom icons to enhance the richness and description of the content.

Supports 60 types of databases

Data module is a strong point of PowerDesigner, which is divided into two stages: CDM (conceptual data model, concept database module) and PDM (physical data Model, entity module). CDM is the analysis phase to clarify the correlation between data, the entity-relational graph (e-Diagram) to represent the attributes of an entity (Entity), and the 1 to 1, 1 pair-many-to-many, or many-to-many relationship (relationship) with other entities.

When the CDM in the analysis phase is converted into PDM, the abstract entity, attribute and relation are mapped to the data table, field, primary key (Primary key) and external index key (Foreign key) of the actual database.

But if PDM is to change the database through the forward engineering, it must adjust the syntax for different brand, PowerDesigner support Oracle, DB2, SQL Server, Sybase, Teradata, MySQL and other brand database, if we differentiate the old and new versions, There are about 60 relational databases supported by PowerDesigner.

Users in the selection of the database card, can be set to change the database directly, or generate SQL instructions, the subsequent use of their own. Version 12.5 PowerDesigner provides native drivers for Oracle, Sybase, SQL Server, and Informix to accelerate access to the database compared to JDBC or ODBC online.

With the gradual popularization of business intelligence, multidimensional data processing is the same as the system development needs to face. PowerDesigner launched the multi-dimensional Diagram (multidimensional map) and ILM (information liquidity Model) in version 12.5. Where multi-dimensional diagram can build multidimensional cube models, while the ILM mechanism is for users of Sybase Replication server or Mobile Link server, providing icon and file synchronization capabilities, Users can replicate the SQL directives generated by ILM and server directives to the actual environment.

Object-oriented module supports multiple programming languages

PowerDesigner Object-oriented module, the application of UML model diagram. Version 12.5 supports UML 2.0 altogether 12 types of model diagrams and supports common programming languages such as Java, C #, vb.net, C + +, and PowerBuilder, as well as IDL, VB6, XML, and WSDL PowerDesigner can support. Users in the new model diagram, select the program language, the use of forward engineering, that is, generate the corresponding program code framework.

In order to better understand the existing system for the benefit of modification, can be generated by reverse engineering model diagram, PowerDesigner support Eclipse, Visual Studio and PowerBuilder development tools, can be set to open directly, and then the details of development.

Ability to manage meta data

The Chinese meaning of metadata (Meta-data) is "data describing data", and in case tool such as PowerDesigner, there are many non-graphical files and data in addition to the model diagram, and they also require versioning and permission control mechanisms. In PowerDesigner, these are categorized in the context of Meta data management.

PowerDesigner through the repository centralized management of BPM, CDM, PDM and UML Model diagrams, and provide version and authority control mechanism, can be used in multiple-person multiple-point development model.

As for the document requirements of the Model diagram, PowerDesigner provides the report generator, the user can quickly produce the data in HTML or Word format by using the sprite steps, choosing English, Roman/Simplified Chinese language, and then applying the template.

PowerDesigner 12.5 Functional Features
