With the classification method, we discovered that many pieces of design information involved in the upper processes are semi-structured. To share and manage the semi-structured design information, we developed a wide area information network (WAIN) on our intranet. It was also possible to verify the changes in those pieces of design information requiring a strict change management.","PeriodicalId":306601,"journal":{"name":"Proceedings of 20th International Computer Software and Applications Conference: COMPSAC '96","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131460243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present methods for verifying that the behavior of PAD (process action diagram) keeps the data constraints of the ERD (entity relationship diagram) using the Z notation. We may improve accuracy of specification by means of giving assurance of validity among different kinds or different abstract levels of diagrams, based on the formal descriptions in Z.","PeriodicalId":306601,"journal":{"name":"Proceedings of 20th International Computer Software and Applications Conference: COMPSAC '96","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128513017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Time-series patterns are represented as a sequence of points in multidimensional spaces, thus traditional indexing methods are not well suited to support this requirement. We propose a dynamic index structure called a TIP-index (time-series pattern index) for efficient manipulation of time-series pattern databases. The TIP-index is developed by improving the extended multidimensional dynamic index file (EMDF). We present the structure and give algorithms for searching and inserting in it. We compare the performance of TIP-index with that of EMDF. The results indicate that insertion and search performance is improved, and we conclude that the TIP-index is efficient for applications in time-series patterns.","PeriodicalId":306601,"journal":{"name":"Proceedings of 20th International Computer Software and Applications Conference: COMPSAC '96","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132475426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These techniques are mainly classified into two categories: time stamp method and version method. These methods limit the representation/manipulation capabilities because the change of class membership for an object is not well specified and the transitional states must be related mutually along the system defined time axis. We propose a method which is basically derived from the object oriented paradigm, for modeling time varying characteristics of entities so as to be free from the above two limitations in the traditional methods. We introduce two representation media: core and surface. The core represents invariant features of entity, while the surface denotes variant features of entity. A snapshot of an entity is represented as an aspect, which is a database instance composed of the core and surfaces.","PeriodicalId":306601,"journal":{"name":"Proceedings of 20th International Computer Software and Applications Conference: COMPSAC '96","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129708993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The identified objects are the basic building blocks of the object-oriented system to be constructed. In order not to disregard relevant objects, most methods advise software engineers to take dedicated steps such as reading books about the problem domain, interviewing customers, etc. We consider two important concerns in understanding the problem domain. First, it is very important to identify all the objects that are required for defining a consistent system, at least in its minimum configuration. Second, identified objects must serve as composable building blocks to construct robust, adaptable and reusable architectures.","PeriodicalId":306601,"journal":{"name":"Proceedings of 20th International Computer Software and Applications Conference: COMPSAC '96","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129990913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with the conventional systems, our hypermedia system has some advantages. First, since our hypermedia markup language is designed using SGML, the language can interchange documents in a system-independent manner and can support content-based and structure-based retrieval. Second, since we apply an object-oriented paradigm to modeling hypermedia data and links, we can inherit the properties and methods of the object-oriented model. Finally, our hypermedia system can provide database management system functions such as query processing, transaction management, storage management, security, crash recovery, and version control of structured document components as separate objects.","PeriodicalId":306601,"journal":{"name":"Proceedings of 20th International Computer Software and Applications Conference: COMPSAC '96","volume":"408 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114286119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the multidatabase environment, changes to the preexisting database system are not allowed because such changes are too expensive. For the integration, high-level semantic description of multimedia data is modeled using the enhanced entity-relationship (EER) model to support content-based retrieval of multimedia data. The EER design is translated into a schema of the preexisting database system and then the translated schema is integrated with the preexisting database schema. The content description can be used to locate pertinent multimedia data, and the identifiers are used to access the multimedia data stored in the multimedia server. However, with only a simple schema representation of the semantic description of multimedia data, high levels of recall and precision of queries may not be obtained because conventional database systems provide only exact matching answers to the query. Thus, we extended the conventional query processing mechanism by providing a modified cooperative query answering mechanism.","PeriodicalId":306601,"journal":{"name":"Proceedings of 20th International Computer Software and Applications Conference: COMPSAC '96","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126964987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
