XML-based standards have become increasingly popular to address some of the interoperability challenges, both in commercial and governmental organizations. However, the number of available XML-based standards has created a situation, where users have difficulties in choosing the most suitable standard, or are forced to support multiple standards at the same time. Therefore, it is important to provide tools for analyzing and comparing different standards. Existing qualitative studies have created tools that can highlight general features by manual analysis. However, in this paper, we argue that additional insights could be obtained by extracting relevant quantitative metrics of the actual XML Schema documents that the standards contain. This study analyzes three prominent e-Business document standards in terms of their quantitative metrics. Based on our results we claim that quantitative studies can enhance the use of the qualitative analysis frameworks and bring attention to useful details when comparing different standards.

Liiketoiminnan kannalta on ensisijaisen tärkeää, että kaikki tieto ja toiminnallisuudet ovat käytettävissä. Järjestelmien tulee siis kommunikoida ja vaihtaa tietoa keskenään. Ongelmana on kuitenkin se, että järjestelmät eivät ole suoraan yhteensopivia, Haasteina ovat esimerkiksi yhteensopimattomat tietotyypit, kommunikointiprotokollat sekä kommunikointityylit (interaction styles). Lisäksi, järjestelmien toteutuksessa ei välttämättä ole otettu huomioon tulevaisuuden integrointitarpeita, mikä edelleen lisää integraatiohaasteita. Viestipohjainen integraatio on yksi lähestymistapa toteuttaa edellä mainittu järjestelmäintegraatio. Viestipohjaisen integraation ominaisuuksia ovat luotettavuus, skaalautuvuus sekä löyhä kytkentä (loose coupling). Viestipohjaisen integraation tehokkaaseen toteuttamiseen tarvitaan teoreettinen malli, kuten palvelusuuntautunut arkkitehtuuri (Service-oriented architecture, SOA) sekä teknologia...

This paper focuses on the accountability aspect of data governance: the assignment of decision rights and responsibilities pertaining to data management. We follow the design science approach and examine how Agile Governance Model (AGM) can be used as the basis of designing a pertinent governance structure for the organizational arrangement of data governance accountabilities. We distinguish common data management roles based on the literature, analyze the organizational coverage of these data governance roles, and demonstrate how AGM can be used to ensure that requisite accountabilities will be addressed throughout the enterprise at the right organizational levels and aspectual loci.

The paper describes how company data is best integrated to a Customer Relationship Management (CRM) system of a charity organization. The case organization is the Finnish Red Cross (FRC). FRC has a newly implemented CRM system, into which they want to import company data from an outside source. The study investigates how this kind of integration can be implemented effectively and what kinds of processes are needed to fulfill the business requirements from different parts of the case organization. In a literature review the concept of good and qualitative customer data is discussed. Then a definition of a company in the CRM system is proposed along with processes to maintain the company data quality. The proposed solution for the integration is tested with an actual implementation and finally the solutions are evaluated. 1

Communication between business and IT experts is challeng-ing, because business requirements are often specified in subjective and vague terms compared to the formality needed for technical implemen-tation. In the service-oriented architectures (SOA) context this ...
