Certification refers to the verification of definite feature of an object, person, or an organization. This verification is often, but not always, provided by some form of external review, education, assessment, or audit. In general, the main certification idea is to bring quality process to a certain software product. One of the core goals to achieve quality in component based product is to acquire reliability, quality and compatibility with other components. We have proposed an evaluation process for certification of component-based software. Certification is performed at component as well as system level. The six factors given by ISO are used to certify the system or component. Some other factors are also taken into consideration for certification process. Unstructured weighting technique is used to assign weights to these seven factors.

Component-Based Software Engineering (CBSE) research is an important emerging area of Software Engineering (SE) that supports and enhances evolution of reusable components useful for creation of software solutions. CBSE has assumptions that components exist in repositories, but this is usually not the case. That is, components are in want. The aim of this work is to design and build generic software components for student management system domain using object oriented methods. Analysis of major school management system functions, data and behaviours was done. Also, pattern-based domain engineering was conducted so as to identify structure points. This led to factoring out generically reusable components. Student management system components were created for implementation using a general-purpose distributed Component-Based Software Development technology model. Consequently, a framework for implementing student management system and related systems was provided. This would contribute to the body of the emerging CBSE practices.

In the testing of a software component-based robot system, generating test cases for the system is a time-consuming and difficult task that requires the combining of test data. This paper proposes an adaptive combinatorial testing method which is based on the input/output relationship among components and which automatically generates the test cases for the system. The proposed algorithm first generates an input/output relationship graph in order to analyze the input/output relationship of the system. It then generates the reduced set of test cases according to the analyzed type of input/output relationship. To validate the proposed algorithm some comparisons are given in terms of the time complexity and the number of test cases.

향후 유비쿼터스 컴퓨팅 환경에서의 임베디드 소프트웨어는 다원화된 네트워크 환경에서 동작하게 될 것이다. 임베디드 소프트웨어가 이 기종의 시스템에서 다양한 형태의 응용 프로그램으로 쉽게 탑재되기 위해서는 설계와 코드의 재사용이 필수적이다. 임베디드 시스템에서 소프트웨어 설계의 재사용이 가능하다면 개발 시 소요되는 시간과 비용이 절감될 것이다. 그러나 임베디드 소프트웨어는 많은 부분이 시스템에 의존적이기 때문에 재사용이 어렵다는 단점을 가지고 있다. 본 논문에서는 이러한 단정을 해결하고자 기존의 MDA 메커니즘과 개선한 Multiple V-model의 접목을 시도하고 임베디드 소프트웨어 컴포넌트 설계의 재사용을 제안하다. 그리고 적용사례로서, 이기종의 임베디드 시스템들에 소프트웨어 컴포넌트를 탑재하였다.

학습자가 인터넷을 이용하여 자신의 수준에 적합한 교육을 자가학습 방법에 의해 습득할 수 있는 시스템을 설계하고 구현한다. 이 시스템은 기존의 이론 습득 후 문제해결 방식이 아니라 문제 해결을 통해 기술적인 내용을 습득하는 형식을 취하였다. 이는 학습자에게 불필요한 부분을 제거하고 반드시 필요한 부분이나 문제를 통해 원하는 기술을 빠르게 습득할 수 있기 위함이다. 이 시스템은 인터넷 환경 및 분산 환경에서 동작하며 웹 서버와 서버 컴포넌트간의 결합에 의해 구현하였다.
