    In our Web-connected world, a business enterprise must have timely information in order to survive. But the applications that collect and manage the information may have been developed independently, over years, using different products and technology. How can such information—scattered across multiple databases and applications—be collected and integrated for access in real time? View full abstract»

    In a large modern enterprise, it is almost inevitable that different portions of the organization will use different systems to produce, store and search their critical data. Yet, it is only by combining the information from these various systems that the enterprise can realize the full value of the data they contain. Information integration is a ubiquitous need for today's businesses. Database fe... View full abstract»

    The World Wide Web Consortium has convened a working group to design a query language for Extensible Markup Language (XML) data sources. This new query language, called XQuery, is still evolving and has been described in a series of drafts published by the working group. XQuery is a functional language comprised of several kinds of expressions that can be nested and composed with full generality. ... View full abstract»

    XML (Extensible Markup Language) has emerged as the standard data-exchange format for Internet-based business applications. These applications introduce a new set of data management requirements involving XML. However, for the foreseeable future, a significant amount of business data will continue to be stored in relational database systems. Thus, a bridge is needed to satisfy the requirements of ...

    Most business data are stored in relational database systems, and SQL (Structured Query Language) is used for data retrieval and manipulation. With XML (Extensible Markup Language) rapidly becoming the de facto standard for retrieving and exchanging data, new functionality is expected from traditional databases. Existing SQL applications will evolve to retrieve relational data as XML data using da... View full abstract»

    The World Wide Web offers a tremendous amount of information. Accessing and integrating the available information is a challenge. “Screen scraping” and reverse template engineering are manual and error-prone integration techniques from the past. The advent of Simple Object Access Protocol (SOAP) from the World Wide Web Consortium (W3C) allowed Web sites to become programmable Web ser... View full abstract»

    With advances in computing and communication technologies in recent years, two significant trends have emerged in terms of information management: heterogeneity and distribution. Heterogeneity (herein discussed in terms of different types of data, not in terms of schematic heterogeneity) pertains to information use evolving from operational business data (e.g., accounting, payroll, and inventory) ...

    Enterprises have been storing multidimensional data, using a star or snowflake schema, in relational databases for many years. Over time, relational database vendors have added optimizations that enhance query performance on these schemas. During the 1990s many special-purpose databases were developed that could handle added calculational complexity and that generally performed better than relatio... View full abstract»

    Information integration has two fundamental aspects, data integration and function integration. Function integration is based on flow technology and adapter technology, and both of these add powerful capabilities to information integration. They provide access to a huge variety of data sources, such as standard applications, home-grown backend systems, and Web services. For accesses that are not r... View full abstract»

    The ability to compensate for previous activities, often in the case of failure or exceptional events, is an important feature of long-running business transactions. In this paper, we present several extensions to existing notions of compensation for business transactions. The extensions are described using a business process modeling language called StAC (Structured Activity Compensation) but are... View full abstract»
