    CARTECH, an SQL-based geographical information system, is presented. It is based on the integration approach, of coupling systems for dealing with traditional, descriptive data, with tools for the management of spatial data. Its key feature is the extension of the relational data model, to deal in a uniform way with both descriptive and spatial features of geographical information. The SQL language has also been extended in order to provide a uniform interface for processing both alphanumeric and spatial-geometric data. The architecture integrates the INGRES database management system for the treatment of non spatial data and the GEOTECH library for the management of spatial/geometric data. The article briefly describes the logical data model and focuses on architectural aspects of the developed integrated system, discussing the extended-SQL interpreter and query processor. An application of CARTECH to land resource management is presented and performances are discussed View full abstract»

    This paper integrates an interoperability architecture, the OSCA architecture, and a distributed transaction processing protocol, the X/Open distributed transaction processing model, into a unified model of large scale interoperability and distributed transaction processing. Applications supporting different business operations are often deployed in heterogeneous environments in which operations often are fragmented. In order to have integrated operations, a loosely coupled system of autonomous applications is required frequently bound together by a distributed transaction processing protocol. This paper describes a model for this configuration. It proposes that the span of control of a transaction manager defines the transaction environment for a single building block, where any two building blocks may not conform to the same supplier's transaction environment. Requirements are imposed upon the interactions of building blocks to support interoperability View full abstract»

    The authors have developed a combined meeting-scheduling cum calendar-management system called CAMEL, that eliminates the tedium of scheduling a meeting. CAMEL uses a hunting feature that enables the tracking of user logins. The approach towards software development is generative as well as declarative, through extensive use of toolkits and reusable software. The authors describe the essential ingredients of CAMEL. It is a fairly complex distributed application using a distributed database and distributed user related information such as preference parameters. Tools from RAPIDS toolkit, especially remote procedure call subsystem, n-party interaction subsystem, are heavily used to produce this application. It also uses many services provided by RAPIDS, such as name server, user information server etc. To maintain consistency of distributed data the application makes use of the 2-phase commit and 2-phase locking primitives provided by RAPIDS View full abstract»

    With the increasing demand for highly complex, integrated and application-domain-specific systems engineering environments (SEEs) more or less specialized components of the SEEs are developed. An important component is the database management system (DBMS). As conventional DBMSs are not useful to fulfill the requirements on highly complex, persistent data structures, specialized DBMSs, namely object management systems (OMS), have been developed. An advantage of OMSs is that they further enhance the integration not only of data but also of processes. Currently several specialized OMSs with significantly different properties such as the data model, architecture and performance are available. As it is very difficult for an SEE developer to select the most appropriate OMS, the authors propose a decision support method which enables an SEE developer to identify his requirements and to compare the evaluation results of different OMSs. Additionally they present a practical experiment where they apply the decision support method for comparing different OMSs View full abstract»

    An efficient, massively parallel optimization technique is developed for solving the dynamic data allocation problem in medium to large scale applications such as computer integrated manufacturing (CIM) systems. This method is based on a significantly reduced feasible state search space. A statistical evaluation framework compares the performance of the proposed technique with other dynamic data allocation strategies. Algorithms are actually implemented for a variety of I/O task activation scenarios, with the number of task activation nodes ranging from 50 to 250. The overall performance of the proposed method has a significant improvement over other optimization strategies, especially as the number of task activation nodes increases View full abstract»

    This paper introduces the features of an advanced user interface builder and application prototyper called SILK. A very brief survey of existing user interface builders is presented, grouping them in categories that reflect their major characteristics. The global architecture of the system and the interoperability between the supported user interface standards are presented. SILK features are presented in detail with respect to the OPEN LOOK implementation. In addition, the significant aspects of SILK as an advanced user interface builder and application prototyping tool are: the unique way it incorporates application code (callback functions) with the user interface widgets, its ability to associate multiple types of callbacks to a widget, and its ability to specify the type of operations (such as user, widget actions, and system commands) to the underlying platform through a basically point and click paradigm. Therefore, SILK not only provides a way to build and prototype new applications in an easier way, but also facilitates the construction of user interfaces for existing applications View full abstract»

    A four stage system design environment is proposed which includes requirements specification, hardware software separation, module specification and system integration stages from a systems integration perspective. As part of realizing this paradigm, a system level specification language, DODAN, is introduced. Based on this specification language, a prototype, DAA, is implemented which addresses the systems level requirements specification stage. Another prototype, DARMS, was implemented to experiment with the module specification stage. This four stage model is described along with experiences in implementing and working with the requirements specification and module specification prototypes View full abstract»

    A general model is presented for the management of a systems integration program, using an enterprise-wide information systems architecture (ISA) as a roadmap. Integration deals with the technical integration of the elements of an information system, as well as the business integration of the information system with the enterprise. The model addresses both of these challenges. The management model defines the scope of the management process and its essential functions, including systems engineering and prototyping capabilities with a defined set of measures and metrics. The supporting ISA template is comprehensive in the business objectives covered, responsive to changes in the business and technologies, and useful in producing a practical information architecture. Examples are discussed of applications to the manufacturing and financial sectors View full abstract»

    The concepts presented in this paper show a possible alternative of the existing post-facto, bottom-up approach used in developing an integrated system. Based on the needs of distributed and complex application systems, the authors propose a pre-planned development process. This integrated approach introduces the notion of a meta-level of control and management which coordinates otherwise independent projects. Domain analysis and integration architectures are identified as the two main components of the proposed generic integration framework. Finally, they describe project management as an embedded sub-task in a generic, domain oriented development effort View full abstract»

    Describes Narada, an environment in which multi-system; applications can be defined using high-level specifications, without dealing explicitly with the details of task synchronization and data exchange. Once an application is defined, it can be executed automatically, providing location transparency and resolving most of the hardware and software incompatibilities. The paper discusses the task specification language used by Narada and shows how it can be used as an intermediate execution language for multidatabase query languages and to support various extended transaction models. The paper also discusses how programs specified in this language can be executed in a heterogeneous computing environment consisting of autonomous software systems View full abstract»

  • Software production strategies-from multiple viewpoints

    Publication Year: 1992 , Page(s): 210 - 218
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (740 KB)  

    Four viewpoints concerning software production are discussed. The first viewpoint says that software production strategy should be explored in the context of a hierarchy of strategies spanning three tiers-business tier, project tier and process tier. The second viewpoint says that any software process can be managed through a six-step framework of defining, measuring, analyzing, controlling, modeling and improving the process. The third viewpoint says that much can be learned from the manufacturing industry on cycle time reduction. In particular, there are different approaches to save time in different time components-learning time, waste time, wait time, and repeat time. The fourth viewpoint recommends the use of the COSMOS model (H.T. Yeh et al., 1991), with its equal emphasis on activity, communication and infrastructure dimensions, to guide software production management View full abstract»

    The implementation of distributed systems includes an extensive component integration effort. Integrating secure components into a distributed system is a task more difficult than standard integration. Current system high distributed secure systems will be transitioned to multilevel secure systems as multilevel secure components become available. Considerations and changes that are required for successful integration of these components are discussed. These changes fall into the categories of concept of operations, security policy, and security architecture View full abstract»
