Background technology
At present, popular object-oriented modeling instrument has the Rational Rose of Rational company exploitation.Domestic have Beida Jadebird's object-oriented modeling instrument.These modeling tools are based on a common modeling language---unified modeling language.Unified modeling language is the object-oriented modeling language standard that OMG initiates, and has become the de facto standard of object-oriented modeling at present.Unified modeling language is by the static structure information of descriptive systems such as class, object, relation, by the dynamic behaviour of descriptive systems such as sequence chart, state transition graph.The description to software systems of this abstract has made things convenient for the interchange of thought between the developer, also provides convenience for document process.Unified modeling language is an extremely successful modeling language, for standardization, the raising efficiency of software of software process have been made huge contribution.But some problems in the process of practical application, have also been run into.Be mainly reflected in two aspects, one, unified modeling language also only is analysis, the design phase that is applied in the software process at present, the model that uses this modeling language to set up can not be carried out, also need the programming personnel that the system of describing with unified modeling language is translated as with a concrete programming language such as Java, the system of C++ description in the process of actual coding.Allow modeling the result---model is participated in execution directly, make model be not only analyze, the workpiece of design, also be executable workpiece, be an important target thereby simplify performance history, improve development efficiency.But, also do not have practical tool to occur at present.Main problem is that the semantic action language that adopts of descriptive model action is complete inadequately, and is also too complicated.
Because unified modeling language is a kind of abstract language, does not comprise the semanteme of specific field,, and can not guarantee to follow domain semantics and field constraint so the model of setting up according to unified modeling language can only guarantee to follow the standard of unified modeling language.
Summary of the invention
The technical problem to be solved in the present invention is, domain knowledge is added in the modeling language, makes unified modeling language go for specific field; By two stage modeling methods, use the applied customization instrument, the network equipment and link are assigned to different model components, realize management to communication network.
