Software architecture, which is the high level model of a software system, should be specified with ADLs (Architecture Description Languages) for its clarity and preciseness. Most of ADLs such as ACME, however, have not come into extensive use in industries since ADL users should learn a distinct notation specific to architecture. On the other hand, UML is a do facto standard general modeling language for software developments. UML provides a consistent notation and various supporting tools during the whole software development cycle. UML, being a general modeling language, does not provide all concepts that are important to architecture description. UML should be extended in order to precisely model architecture. A number of researches on architecture modeling based on WML have been progressed. Ail of them, however, are based on the UML1.x. UML2.0 embraces much more concepts that are important to architecture modeling than UML1.x. In this paper. we defined an architecture modeling language based on UML2.0. We defined Generic ADL by extending UML2.0 and applied the defined Generic ADL to a restaurant reservation system.

Software architecture is the high level model of a software system. It should be specified with ADLs (Architecture Description Languages) for its clarity and preciseness. Most ADLs such as C2SADL have not come into extensive use in industries since ADL users should learn a distinct notation specific to architecture, and ADLs do not address all stakes of the development process that is becoming diversified everyday. On the other hand, UML is a do facto standard general modeling language for software developments. UML provides a consistent notation and various supporting tools during the whole software development cycle. But, UML is a general modeling language and does not provide all concepts that are important to architecture description. UML should be extended in order to precisely model architecture. In this paper, we defined a C2 architecture modeling language as a UML2.0 profile. We applied the defined C2 architecture modeling language to the modeling of a restaurant reservation system.

Recently, the scope of user interface is increasing the relative importance in software development dramatically. As a result, there are various relative technologies like as SWING, MFC, Web 2.0, and etc. However, most current software developments are progressed in separate development process with user interface part and business part respectively. This causes the problems, like as a difficulty in the integration process, an development period's delay, and a poor reusability for the constructed models. That is, the extendability and reusability of the created models is being decreased because UI modeling is not systematic and hierarchical, and the consistent integration technique between UI modeling and business modeling does not supported. To solve these problems, this paper proposes an unified and systematic UI modeling process based on UML, using the hierarchical metamodel according to the abstraction levels of development phase. We suggest an UI metamodel, which contains a hierarchy by layering the modeling elements in PIM and PSM based on maturity degree of the development. An hierarchical modeling process combined UI modeling and business modeling is built by applying the UI and business metamodel in terms of three modeling phases(concept/specification/concrete). The effectiveness of the modeling process is shown by applying the proposed process into an Internet Shopping Mall System. Through the exploratory results, the hierarchical UI metamodel and process can produce systematic and layered UI models. This can improve the quality and reusability of models.
