Efficient search and retrieval mechanisms are needed to deal with the heterogeneousness and complexity of this environment. In larger enterprises, business documents are typically stored in disparate, autonomous content repositories with various formats. Strategic and technological contingencies within the elaboration of integration mode.ĮNTERPRISE INFORMATION SEARCH SYSTEMS FOR HETEROGENEOUS CONTENT REPOSITORIES Thus we show the importance of organizational,
The first approach represents the necessity of using organizationalĬonfiguration to define possible IS integration modes. This paper shows the importance of carrying out a double approach to This article draws on two case studies of firms having realized more than 10 mergers andĪcquisitions between 19. Today Information Systems (IS) integration constitutes one of the major success factors of mergers andĪcquisitions.

The internal logical structure of the software system is used to create Software into client-server architectures. Propose an incremental process for transforming monolithic business In this paper, we concentrate on the transformation issue Thus, a common problem in business software is the cost effectiveĪnalysis, documentation, and transformation of business software. Required due to a change in the business processes of the This so-called legacy problem is extremely cost intensive when aĬhange in the software itself or the hardware platform is To the rapidly changing hardware and software technologies. However, it is difficult to adapt these software systems Which is essential for the enterprise using the software and TRANSFORMATION OF LEGACY BUSINESS SOFTWARE INTO CLIENT-SERVER ARCHITECTURESīusiness software systems in use contain specific knowledge This paper presents a portlet selection model that guides the portal developer in choosing the best portlet, among a set of portlets with similar functions for specified tasks and user objectives, in accordance to five quality measures, namely, functionality, reliability, usability, efficiency and reusability, and other three characteristics not related to the quality but important to carry out the selection. Portlets are web components, and they can be thought as COTS but in a Web setting. Specifically, this work focuses on portlet-based portals. Hence, appropriate quality model should be available to measure and drive portal development. Nowadays, it is very easy for users to change from one portal to another, so improving/assessing portal quality is a must. The success of a portal depends on customers using and returning to it. The use of Web portals continues to rise, showing their importance in the current information society. Mª Ángeles Moraga, Coral Calero, Mario Piattini and Oscar Díaz We also present the results of an experiment demonstrating the effectiveness of our methodology. In this paper, we then propose a semantic-independent methodology targeted at (i) supporting the data warehouse design and creation, and (ii) deriving information on total quality of the built Data Warehouse. Since this is not a trivial task, especially for databases characterized by a large number of tables and attributes, an expert is often required for correctly selecting the most suitable attributes and assigning them the correct roles. However, the choice of which attributes have to be considered as dimensions and which as measures heavily influences the effectiveness of a data warehouse.
