The safe attributive management of 1 data is in object-oriented development system, the management of data organizes management with object type. Systematic data has two kinds, one kind is the object that concerns with data directly, wait like Document, another kind is the target that offers a product to develop support, wait like ITEM, FOLDER, EC. It is which kinds of object no matter, have relevant data aspect and operation method side. For management of safe to concerning the data lateral of the object with data directly attributive, basically adopt following two kinds strategy. It is safe to be being defined according to the sensitive degree of data level, and should realize the nest of level, the data with the OK and compatible safe low level with safe high level. Another defines the category of data according to the limits of product data namely. Distinct category differs on behalf of the product the data of component. No matter be why to be planted the object of the type, have proper operation method definition. The strategy that this respect adopts if divide these operation method,be two sort only model, it is open method, also namely the operation method under this kind of management can be used to developing any users among the system. Need the method of accredit however, also should plant namely the operation method under management must pass corresponding accredit ability to be operated quite. Relevant data belongs to He Chongan total level and safe category is defined when establishing this data target, and the definition of the safe attributive of the operation method to data object has in systematic government. 2.
The safe attributive management that the group of safe attributive administrator that 2 staff group organizes organizes basically is to point to the management of part and the limits of authority that its have. Basically the administration that carries pair of staff groups realizes the security that article place takes and attributive government strategy, what because be opposite directly,all sorts of data objects undertake operating is staff group organization. The organization of personnel organizes all sorts of development groups according to developing the mission namely, form the group that works in coordination individually. The safe limits of authority that develops a group manages even if gift its are safe to some kind level (the concern that has nest) have authorization with the certain operation method of the data object of safe category. Same personnel can be divided belong to different development group, and what each development group place have some safe limits of authority is integrated it is the limits of authority that this personnel has accordingly. The interior that developing a group individually is returned should the responsible state according to the task, determine different level. To this kind of problem, the measure that article place adopts is will corresponding working group departure, undertake differentiating according to certain level, arise from which a few child working group, have the authorization of safe attributive to relevant working group respectively again. 2.
The development of the product of safe attributive management of 3 flow is as flow undertake stage by stage and finish with each passing day, among them the main goal that the flow of data is flow implementation, at the same time as development undertake, the condition of each data also changes in progressively happening, of each link in executive flow is the development group that defines according to the task or personnel, whether can its have correct operation to going from place to place data, it is the safe attributive pilot with certain need. That is to say, flow management made sure accurate data delivers right hand with right kind in, but each personnel whether the target that handling this data correctly is safe attributive management. Additional, because count the flow that occupy, the management of this kind of safe attributive is dynamic management, must have the program of attributive management in detail. Discuss the safe limits of authority that data switch takes between flow link to run strategy above all. Different flow link is by what differ personnel carries out different job, meantime accompanies what a move in chess or a movement in wushu occupies to add, revise, delete wait for design movement. Because the definition of data is independent, specify the safe level of this data object and safe category namely, the staff that needs to issue a segment only so has proper role to have corresponding to what gift operation limits of authority. Have different level to need to handle a case respectively to among them data, arrangement be subordinate to belongs to those who have corresponding limits of authority child the group member of the working group will carry out corresponding circumstance can. The condition of data is one of product development serious content, also be the consideration factor that undertakes product lifecycle manages, as associated as photograph of product data condition safe attributive management also is the content that must consider. Generally speaking the data in product development basically has development state of affairs, project to change position, release applied condition, file condition to wait. Be aimed at this kind of circumstance, following strategy that formulate. Be aimed at the data of some kind of safe category, when defining its to produce condition to change, of corresponding attributive change a condition. Different position is different the operation circumstance of the data of attributive is different. 2.
4 development system is overall and safe attributive management model 2.
5 conclusion and the constituent model that those who look into above paragraphs place to narrate is traditional PDM system and safe attributive manage mode. The progressively development that carries out as enterprise informatization and comprehensive, again a few new ideas need amid to undertake reflecting. Among them a few crucial technologies are faced to undertake expectation below. (1) the administrative process that the constituent model with the static orthodox change to trends and safe attributive management basically are a kind of static state, the change of the safe attributive that to data place of demand of going from place to place produces does not have very good management. And the working flow that the main carrier form that data flows is product development. Because this should design an attributive change the modification control of drive to perhaps get a mechanism, design attributive is in organization, project, branch, lifecycle each condition between undertake delivering. The basis that the set that designs attributive generally speaking perhaps changes has a few kinds as follows: Of regulation of regulation of company change government, company product configuration, design carry out or experience. To implement the static change to trends, need basis project, organize or branch and product lifecycle the combination between each condition concerns, does the design go out alleged? " of matrix of Quot; company limits of authority. This matrix should be complete described a business in the center the attributive that data flow place brings analyses a result. (2) be opposite one-sidedly at present to overall change the understanding of PDM had completed the process that develops administrative change to the product from simple product data management, but the idea that more products develop applied limits of management to just develop this one narrow sense in the light of the product among actual application or limits. The method on this kind of understanding and application has made the systole of the executive limits of PDM and the difference that are the same as advanced design thought. Because this should be in above all,the concept of safety and lifecycle of product of lieutenant general of attributive management function is reflected go in, with as far as possible cover overall product data position. Data the safe regulation that in different position its have also is different. (3) complete corresponding action through the different link in flow and the essence that runs product development around the safe attributive of movement and flow comes true, should spread out the management of safe attributive around movement and flow so. ⒌ of bank of the design that basically includes technological process and having enough is able to bear or endure newly-risen sun of scull of Mi of bath T pulls Piao to fear laborious; Does Kou of δ of grave of colourful of muddleheaded of brilliant make an appointment with Pan of basketry Chun > is contraction of shipboard of accept of Mei of board of besmear of dusk of of post Tiao washing with watercolors troubled by show off of ⒃ of ā of a surname of graceful ㄏ big and thick is frequency of Piao of fan of majestic Huan of Tuo of moth of coil of source of tip of of sole of of deficient of bail of childish of elder brother С graceful? / P>(4) systematic demand to come true afore-mentioned all sorts of movements and thought, PDM system should provide a few functions that be as follows. If found and distribute whole tool bag, include among them: Working description, change context, relevant documentation, send an envelope, get the ability that alters the history to wait; Backdate works to in the past condition; The job that records flow and change a condition; The tool that the system wants to provide administrative authorization, responsible ability, task in designing circuit is carried out. Anyhow, different PDM system carries out the basis to differ object-orientedly, should manage constituent model, safe attributive process, product to develop the reasonable organization such as lifecycle of process, generation, implementation is based on the flow design of matrix of company limits of authority.
