The paper analyses graph oriented ontology transformation into conceptual data model. A number of methodswere proposed to develop conceptual datamodels, but only fewdealswith knowledge reuse. In this paperwe present an approach for knowledge represented by ontology automatic transformation into conceptual data model. The graph transformation language is presented and adapted for formal transformation of ontology into conceptualmodel. Details and examples of proposed ontology transformation into conceptual data model are presented.

Žiniatinklio paslaugų sistemos, kurių funkcionalumas yra panašus, dažnai yra kuriamos nenaudojant kitų įmonių sukauptų panašių dalykinių sričių žinių. Dėl to sistemose pasikartoja tų pačių klaidų, pavyzdžiui, nustatomi ir vėliau sistemoje naudojami ne visi svarbūs koncepcinio duomenų modelio objektai bei sukuriamas netikslus ir neišsamus verslo taisyklių rinkinys. Siekiant išspręsti paminėtas problemas kuriant informacines sistemas siūloma naudoti dalykinės srities ontologiją. Šiame darbe ontologijų taikymo būdas derinamas su žiniatinklio paslaugų sistemomis, šitaip siekiama pagerinti jų kūrimo procesą. Atliekant tyrimą buvo siekiama geriau suprasti žiniatinklio paslaugų sistemoje taikomas taisykles ir parinkti dalykinės srities ar žiniatinklio paslaugų ontologiją, kuri galėtų būti tinkama nustatant taisykles. Todėl žiniatinklio paslaugų sistemos taisykles suskirstėme į sąveikos, verslo logikos, naudojimo, prieigos ir sekų taisyklių klases. Sąveikos taisyklių klasei nustatyti siūloma naudoti žiniatinklio paslaugų ontologiją, verslo logikos, naudojimo, prieigos taisyklėms išgauti – dalykinės srities ontologiją, o nustatant sekų klasės taisykles gali būti naudojamos abi minėtosios ontologijų rūšys. Pasiūlytas ontologijų naudojimo žiniatinklio paslaugų sistemoje būdas patikrintas kuriant publikacijų e. bibliotekos koncepcinį duomenų modelį ir taisyklių rinkinį.Pagrindiniai žodžiai: žiniatinklio paslauga, ontologija, verslo taisyklė, koncepcinis duomenų modelis.Ontology-based web services system developmentRūta Dubauskaitė, Olegas Vasilecas Summary Web services systems are often created from scratch despite of already existing systems with similar functions. Therefore the same mistakes can arise in development of the systems, for example: important concepts of data model are not defined, incorrect rules model are created. Ontology is proposed to use in the development of information system for getting domain knowledge.The ways of using ontology in the development of web services systems are analyzed in the paper. The aim of this research is to improve the process of web services system development. The analysis of web services, ontology and business rules shows that it is advisable to use ontology to create set of business rules, conceptual data model.We propose to classify the rules of web services systems in order to better understand them and choose better ontology for their elicitation. In the paper ontology approach is applied for web services systems. It is proposed to use domain ontology for elicitation of domain, access, usage and orchestration rules, web services ontology can help to elicit choreography and orchestration rules. Suggested approach is examined developing prototype of university e. publication web services system. Suggested classification of web services systems rules enables easier to elicit rules and allows choosing suitable source of rules (web service ontology or domain ontology). It is found that using ontology in development process of web services systems allows creating more correct set of rules and conceptual data model.

PurposeWeb applications are subject to continuous changes and rapid evolution triggered by increasing competition, especially in commercial domains such as electronic commerce. Unfortunately, usually they are implemented without producing any useful documentation for subsequent maintenance and evolution. Thereof, the maintenance of such systems becomes a challenging problem as the complexity of the web application grows. Reverse engineering has been heralded as one of the most promising technologies to support effective web application maintenance. This paper aims to present a reverse engineering approach that helps understanding existing undocumented web applications to be maintained or evolved.Design/methodology/approachThe proposed approach provides reverse engineering rules to generate a conceptual schema from a given domain ontology by using a set of transformation rules. The reverse engineering process consists of four phases: extracting useful information; identifying a set of ontological constructs representing the concepts of interest; enriching the identified set by additional constructs; and finally deriving a conceptual schema.FindingsThe advantage of using ontology for conceptual data modeling is the reusability of domain knowledge. As a result, the conceptual data model will be made faster, easier and with fewer errors than creating it in usual way. Designers can use the extracted conceptual schema to gain a better understanding of web applications and to assist in their maintenance.Originality/valueThe strong point of this approach is that it relies on a very rich semantic reference that is domain ontology. However, it is not possible to make a straightforward transformation of all elements from a domain ontology into a conceptual data model because ontology is semantically richer than data conceptual models.

Процессные модели предметной области широко применяются при проектировании баз данных, а именно в ходе концептуального моделирования данных. Предлагается решение проблемы неоднозначности преобразования процессных доменных моделей типа SADT в концептуальные модели данных. Domain process models are widely used in database design, namely in conceptual data modeling. The solution of the problem of ambiguity of transformation of process domain models of the SADT type into conceptual data models is proposed.

Recently in our country, the construction of buildings become more complex and it seems that strata objects database becomes more important in registering the real world as people now own and use multilevel of spaces. Furthermore, strata title was increasingly important and need to be well-managed. LADM is a standard model for land administration and it allows integrated 2D and 3D representation of spatial units. LADM also known as ISO 19152. The aim of this paper is to develop a strata objects database using LADM. This paper discusses the current 2D geospatial database and needs for 3D geospatial database in future. This paper also attempts to develop a strata objects database using a standard data model (LADM) and to analyze the developed strata objects database using LADM data model. The current cadastre system in Malaysia includes the strata title is discussed in this paper. The problems in the 2D geospatial database were listed and the needs for 3D geospatial database in future also is discussed. The processes to design a strata objects database are conceptual, logical and physical database design. The strata objects database will allow us to find the information on both non-spatial and spatial strata title information thus shows the location of the strata unit. This development of strata objects database may help to handle the strata title and information.
