INTEGRATION OF URBAN SPATIAL DATA MANAGEMENT AND VISUALIZATION WITH ENTERPRISE APPLICATIONS USING OPEN-SOURCE SOFTWARE

Abstract. In recent years, efficient management of urban spatial data has played a major role in improving urban planning projects both in terms of cost and time savings. Since urban planning projects involve various disciplines like city planning and architecture as well as working with different spatial data, one of the main challenges is how to integrate and manage these multimodal data for a proper workflow. Currently, the involved companies are using project management and accounting systems, so called Enterprise Resource Planning (ERP) systems to handle these complex urban projects - that partly handle the same data objects as stored in urban spatial databases but without any spatial reference. Embedded in the application example of an urban redevelopment area, which according to the German Urban Development Promotion Act aims at financially promoting urban districts in need of renewal, project-related spatial and non-spatial data that were previously kept separate are linked and integrated. Therefore, our work presented here bridges the gap between these two types of application systems, the non-spatial accounting system called Finanz Management System (FMS) and the urban spatial databases. FMS manages information related to parcels, buildings, property owners, as well as the legally required payments connected to urban development, while an urban spatial database manages the geodata. We describe the prerequisites, procedures, and software development steps for coupling different types of applications by providing an example of the Enterprise Application Integration System (EAI). Our innovative integration process aims at making information from the spatial database available in FMS and vice versa, and allows updating the corresponding databases. Our work shows the potential of open-source software for cadastral data processing and visualization as well as accounting procedures for urban planning projects.

Formal foundations for responsible application integration

Enterprise Application Integration (EAI) constitutes the cornerstone in enterprise IT landscapes that are characterized by heterogeneity and distribution. Starting from established Enterprise Integration Patterns (EIPs) such as Content-based Router and Aggregator, EIP compositions are built to describe, implement, and execute integration scenarios. The EIPs and their compositions must be correct at design and runtime in order to avoid functional errors or incomplete functionalities. However, current EAI system vendors use many of the EIPs as part of their proprietary integration scenario modeling languages that are not grounded on any formalism. This renders correctness guarantees for EIPs and their composition impossible. Thus this work advocates responsible EAI based on the formalization, implementation, and correctness of EIPs. For this, requirements on an EIP formalization are collected and based on these requirements an extension of db-net, i.e., timed db-net , is proposed, fully equipped with execution semantics. It is shown how EIPs can be realized based on timed db-nets and how the correctness of these realizations can be shown. Moreover, the simulation of EIP realizations based on timed db-nets is enabled which is essential for later implementation. The concepts are evaluated in many ways, including a proof-of-concept implementation and case studies. The EIP formalization based on timed db-nets constitutes the first step towards responsible EAI.

Integration of Independent Applications and EAI Systems using Service Oriented Enterprise Bus and Open System Application Development Standards

Businesses today are dependent on custom enterprise software and web applications from independent software developers and software companies. This creates a lot of problems such as integration, interoperability, security, and system maintenance. Enterprise Application Integration (EAI) and Business-to-Business integration control several key technologies and swift advancement in technology to meet the increasing needs for integration in the enterprise which often results in a lot of challenges due to differences between one proprietary approach and another. This paper seeks to provide an approach of integrating independent applications and EAI systems by using Web services standards and open application development standards in dealing with the challenges faced in integrating applications. This will make it possible for organizations to add a new layer of abstraction that is open, standards-based, and easy to integrate with any new or existing system and also make easy for data discovery as well as building of new concepts from existing data. The combination of Service Oriented Architecture and Web services will be used to provide a rapid integration solution and also publishing services in a manner that new concepts can easily be built from existing services.

The General J2EE-Based Enterprise Information Platform

A Enterprise Application Integration system named Enterprise Information Platform is designed and implemented in a J2EE environment to ensure data share across any operating system and network. Based on message mechanism, JMS is used to transfer message and XML is chosen to organize the format of communication data which can provide services and application programming interfaces to integrate heterogeneous data. This system has been successfully used in some enterprise, and its generality, openness, multiplexing and extensiveness has also been proved in practice.

Research on Enterprise Application Integration Based on Service Oriented and Workflow

Aiming at the disadvantages like the enterprise application system scalability, integration and interoperability is not strong, neglecting the business process integration, the integration platform lacks flexibility and adaptability, based on service oriented and workflow technology system, Service-oriented and for integration of foundation, enterprise application integration system solutions were proposed. To realize loosely coupled, business process integration, high integration and interoperability strong application integration system we need discuss enterprise application integration the architecture and hierarchical model.

Self-adaptive middleware: Supporting business process priorities and service level agreements

This paper deals with quality of service, defined at the application level, with respect to business constraints expressed in terms of business processes. We present a set of adaptive methods and rules for routing messages in an integration infrastructure which yields a form of autonomic behavior, namely the ability to dynamically optimize the flow of messages in order to comply with SLAs according to business priorities. EAI (Enterprise Application Integration) infrastructures may be seen as component systems that exchange asynchronous messages over an application bus, under the supervision of a processflow engine that orchestrates the messages. The QoS (Quality of Service) of the global IT system is defined and monitored with SLAs (Service Level Agreements) that apply to each business process. The goal of this paper is to propose routing strategies for message handling that maximize the ability of the EAI system to meet these requirements in a self-adaptive and self-healing manner, i.e., its ability to cope with sudden variations of the event flow or temporary failures of a component system. These results are a first contribution towards deployment of autonomic computing concepts into BPM (Business Process Management) architectures. This approach marks a departure from previous approaches in which QoS constraints are pushed to the lower level (e.g., the network). Although the techniques, such as adaptive queuing, are similar, managing QoS at the business process level yields more flexibility and robustness.

Enterprise application integration systems and architecture – the case of the Robert Bosch Group

Today, most organisations are using packaged software for their key business processes. Enterprise resource planning, supply chain management, customer relationship management and electronic commerce systems enable organisations to improve their focus of using information systems to support their operational and financial goals. This article argues that the need to integrate these packaged software applications with each other as well as with existing or legacy business applications drives the need for a standardised integration architecture to more flexibly implement new business processes across different organisations and applications. To illustrate the components of such an architecture, a case study undertaken at the Robert Bosch Group provided necessary empirical evidence. The Robert Bosch Group has evaluated different enterprise application integration (EAI) systems to achieve a standardised integration architecture. The article describes a reference architecture and criteria for the classification of EAI systems which are derived from different integration approaches.
