The many electron document that the PDM that the development of 1 software technology makes PDM architecture advanced with each passing day and original basically uses at managing CAD system to arise, belong to the accessary system of CAD tool, appear at 80 time initial stage, as a result of at that time the limitation of each respect technology, use simple C/S structure and technology of structured process designing normally; Arrived 90 time metaphase, appeared a lot of specialized PDM products, these PDM products are based on large concern database without one exception almost, use object-oriented technology and mature C/S structure; Recently, the ceaseless development as Web technology and target concern database (ORDBMS) increasingly mature, appeared to be based on Java3 paragraph the product of the 3rd acting PDM of type construction and Web mechanism. Should say, PDM architecture is increasingly advanced as the development of technology of computer soft hardware, architecture arrives by C/S structure C/B/S structure, process designing technology arrives from original structured process designing complete object-oriented technology, use programming language arrives from Fortran, C C + + , Java, XML, adoption database involves department database to the object from relation database. 2 be based on Java, Web currently, use C/B/S the PDM system with the mainstream current and advanced PDM of construction of 3 paragraphs of type uses Web technology and many industry standard generally, its architecture is shown like the graph. Whole can be divided it is 5, layer of layer of rock-bottom service layer, Wu of PDM nucleus be convinced, PDM application component, applied tool layer and executive concept layer. 2.

The computer hardware environment that layer of 1 rock-bottom platform basically points to to different compose distributings, operating system, network and communication agreement, database, among wait for the environment that prop up. The development of platform of ground floor of current PDM software basically has two characteristics: It is to get used to ability to expand ceaselessly, can support more and more soft hardware environments, PDM manufacturer devotes oneself to to roll out the PDM system that gets used to more platform all the time. On hardware environment, arrive from the simplest user terminal, PC high-end workstation and server can run corresponding PDM system. 2 it is development of direction of price of rock-bottom platform Chao Lian. On the operating system, unix still is the main service platform that most PDM uses, but as a result of cost cheap, interface friendly, operation is convenient wait for reason PC/Windows to be in sadly him dilate feudal. If its server such as Metaphase, IMAN, PM is carried or very much large PDM moves below Unix environment, but rolled out respective personal computer edition in succession. And waiting for new student noble like Windchill is more it is main platform with PC/Windows, just roll out Unix version later. As a result of system of company level PDM giant data bulk, high performance asks, because this bottom number of plies occupies a library not to have one exception to be centered at the large database such as Oracle, SQL Server, Sybase almost, especially the first selection that Oracle is system of a lot of PDM or choose a database alone. In addition, PDM software supports the local area network such as TCP/IP, IIOP, NetBIOS and HTTP and agreement of standard of wide area newwork almost. 2.

2What product of software of PDM of layer of Wu of PDM nucleus be convinced points to commonly is layer of Wu of nuclear be convinced and layer of PDM application component, because differ somewhat on both function, discuss respectively so. Below C/S structure, layer of Wu of nuclear be convinced is server end commonly, the client carries software to use component with respect to what belong to PDM, below C/B/S structure, both moves in server end, but the respect such as installation is bought to be able to differ somewhat in software product, wu of nuclear be convinced is must, and applied component can be chosen. The EServer of the Windchill Foundation that for instance the object of Metaphase manages frame, Windchill, IMAN belong to respective core to serve a layer. Layer of Wu of nuclear be convinced is model of a group of objects actually, it basically fulfils 3 functions, it is to be down join to operate database, 2 it is to be PDM application component to provide basic service up, 3 it is to be application software to offer port of applied process designing (API) with compositive application software. In addition, some PDM software still joined Web processor to make in core layer. 2.

3Component of application of PDM of layer of PDM application component is actually by a group of programs that call PDM base service (interface) the functional module that comprise and can fulfil certain application function. Circulate administrative application package e.g. the job, the functional module that the flow of the work that finish that defines tool, job to shed executive machine, job to shed the composition such as monitoring tool by working shedding namely manages. The applied component that each PDM manufacturer abounds him ceaselessly (if pursue one) , offerred like Metaphase include lifecycle management implement, modification control management implement, product structure manages implement, the product configures management implement, component a group of things with common features management implement, use at waiting for application software with CAx/DFx/ERP/CSM/EC/SCM compositive Metaphase application is compositive interface, visible tool, design support in coordination type of tool, number. Unified user interface also classify applied component layer, almost all PDM support be visited through Web means and operate PDM, the newer PDM that waits for C/B/S structure like EMatrix, Windchill is carry for the client with Web browser, and Metaphase, IMAN also rolled out the client end that is based on Web severally in succession. 2.

Tool of application of layer of 4 application tool basically shows the project such as CAx/DFx designs the office such as domain software, Word to use software and the other application software beyond all PDM, PDM comes true with these application software through a variety of means compositive. 2.

The management pattern that in the final analysis of PDM of layer of 5 executive concepts is not an enterprise is tool of a kind of software only, tool of this kind of software runs the ability below mode to produce its effect in advanced company only, because of this PDM carry out cannot leave CE almost (collateral project) , CPC (in coordination product business affairs) , VM (fictitious make) , SCM (supply catenary government) , the advanced administrative concept such as ISO9000 and quality standard. Fall in the guidance of these advanced thoughts only, the executive ability of PDM ensures the success produces bigger effect. On the other hand, PDM is carried out is the most effective tool that these advanced concepts are able to carry out successfully and one of methods. PDM software firm is in market its software product while, also be in the concept that promotes it, if PTC proposes the CPC, 4C concept that Metaphase proposes it,wait. And PDM software is one kind passes executive ability to perfect ground and enterprise are united in wedlock and reflect software of its value ground only, accordingly, executive concept row was in the stratosphere of PDM architecture.
