The ‘seamless’ integration of a collection of information systems has been recognised as vital in promoting and realising the collaborative aspects of work. This emphasis on the collaborative role of integration supplements other studies in CSCW focusing on more singular tools for collaboration. Empirically, we analyse the design and use of an electronic patient record system (EPR) in large hospitals in Norway. We discuss the conditions for and types of integration of EPR with the host of related information systems in hospitals. We formulate design principles for the integration of collaborative information systems based on a pragmatic study of the productive role of redundant, fragmented and ambiguous information.

Enterprise Resource Planning (ERP) systems were introduced into companies to solve various organisational problems, and to provide an integrated infrastructure. Although ERP packages offer advantages to enterprises, they have not achieved many of their anticipated benefits. Autonomous and heterogeneous applications co-exist in companies with ERP systems and integration problem having not been addressed. This paper seeks to make contribution to this area by studying and analysing ERP problems through an Internet based survey. Responses are analysed in detail and a new approach to integration problem; the Enterprise Application Integration (EAI) is examined. EAI is a new class of integration software that leads to the development of strategic business solutions by securely incorporate functionality from disparate applications. EAI could be the solution to ERP’s integration problems.

Abstract. The pressure towards tighter or ‘‘seamless’ ’ integration of health information systems is a recurring issue with both practical and analytical relevance. It taps into a discourse in the IS literature in general and organisation and management science in particular. Unfortunately, the prevailing perception of integration in the IS literature is as a predominantly technical issue. The CSCW literature, however, is attentive to the socio-technical aspects of integration. Building on this – but supplemented with recent elaborations in science studies – we aim at exploring the unintended consequences of information systems integration. A user-led perspective implies emphasising the tailoring to local needs based on in-depth studies of the micro practices. We argue, however, that the condition for such an approach is radically undermined by politically motivated, regional changes towards integration with implicated standardisation. Enforcing order in the form of standards across multiple local settings, seemingly a prerequisite for tight integration, simultaneously produces disorder or additional work in other locations for other users. Empirically, our study is based on a large, ongoing integration effort at the University hospital of Northern Norway, specifically studying work practices and perceptions across multiple laboratories. Key words: integration, standardisation, unintended consequences, work practices 1.
The Dublo Architecture Pattern for Smooth Migration of Business Information Systems: An Experience Report

While the importance of multi-tier architectures for enterprise information systems is widely accepted and their benefits are well published, the systematic migration from monolithic legacy systems toward multi-tier architectures is known to a much lesser extent. In this paper we present a pattern on how to re-use elements of legacy systems within multi-tier architectures, which also allows for a smooth migration path. We report on experience we made with migrating existing municipal information systems towards a multitier architecture. The experience is generalized by describing the underlying pattern such that it can be re-used for similar architectural migration tasks. The emerged Dublo pattern is based on the partial duplication of business logic among legacy system and newly deployed application server. While this somehow contradicts the separation-ofconcerns principle, it offers a high degree of flexibility in the migration process and allows for a smooth transition.

Abstract. The interoperability of information systems has been pursued for a long time by researchers and practi-tioners. It involves the exchange of information among different systems, and requires agreement on formats and application domain concepts. Interoperability may also encompass commonality of user interaction and system behavior. One of the interoperability problems which has been investigated for over 20 years on different contexts is that of integration of heterogeneous data. However, even this fundamental and old problem is very hard to solve. The data integration problem may be considered from many perspectives and on increasing levels of complexity or abstraction. This paper reviews the literature about interoperability in general, and integration of heterogeneous geographical data in particular, presents several facets of the data integration problem, and some approaches to deal with them. 1

Abstract. Interoperability is a key property of enterprise applications, which is hard to achieve due to the large number of interoperating components and se-mantic heterogeneity. Platform-based approaches such as service-oriented ar-chitectures address the technical integration of systems. However, a deep inte-gration needs to cover the whole lifecycle of the interoperable system. We pro-pose method engineering as a means for encoding situated knowledge about achieving interoperability in the form of method chunks. We analysed the field of interoperability for enterprise applications and propose that a tool modelling the business- and ICT-related choices in the form of method chunks is needed for a knowledge-based solution of interoperability problems. An industrial case is included to back our claims. 1

The term "Federated Databases" refers to the data integration of distributed, autonomous and heterogeneous databases. However, a federation can also include information systems, not only databases. At integrating data, several issues must be addressed. Here, we focus on the problem of heterogeneity, more specifically on semantic heterogeneity -- that is, problems rela ted to semantically equivalent concepts or semantically related/unrelated concepts. In order to address this problem, we apply the idea of ontologies as a tool for data integration. In this paper, we explain this concept and we briefly describe a method for constructing an ontology by using a hybrid ontology approach.

Abstract: Dynamic HTML documents on the Internet contain useful information that can be reused by other applications. Unlike XML documents, the problem with HTML documents is that they do not have any semantics for the data in the page. Although a programmer can write a program that retrieves a peace of information from a specific HTML document available on the Internet, it will be very difficult to write several different programs to retrieve information from different dynamic HTML pages with varying formats. This paper develops a simple and generic approach to retrieve dynamic HTML Internet-based information. In this approach, several techniques that can be used to retrieve data from dynamic HTML documents are developed. These techniques were developed as a Java class which programmers can use to integrate and reuse HTML Internet Information for other real-time applications that need this information for their operations. The integrated Internet information can be weather information, stock prices, and top news. A number of experiments were conducted to measure the performance of these techniques. In addition, the paper discusses a number of applications that may benefit from this approach.
