Two New Books on UNIX and Data Base Security

The widespread use and availability of microcomputers and local area networks (LANs) has drastically changed the way in which users do computing and access mainframes. Communications technology and LANs have increased the capability to interconnect computers remotely and locally. Users are demanding access to mainframe data bases, whether it be through dial-up lines, gateways, or 3270/coaxial connections. Unfortunately, many organizations are still focusing solely on physically and logically protecting the mainframe and its applications, which may not be sufficient to ensure the security of information on these systems.

Statistics concerning computer crime indicate that most computer crime is committed by insiders, which implies that these criminals already have some form of access to the mainframe. Because it is common for log-on, user identification, and other data for these mainframes to travel over communications lines in cleartext, anyone with access to a microcomputer connected to the mainframe can capture this information without being detected.     

Industrial application integration using the unification approach to agent-enabled semantic SOA

Within the enterprise, information infrastructure as the mean to bring together different software applications is the key component to enable cooperation and information and knowledge exchange in an open-distributed environment. The paper addresses the issues of industrial application integration in business processes using agent-enabled service-oriented architectures (SOA). In this paper, we show that agent-enabled SOA can play an important role for service integration. Our framework combines Web services (WS) and intelligent agent technologies orchestrated by a business process management system. This framework looks for unification of agent and WS service models, is grounded in a semantic SOA of an agent platform and is supported by the Component Agent Platform Over .NET Framework agent platform tools. We describe the architecture and illustrate the approach by an industrial application scenario from petroleum wells’ drilling.     

From proprietary to open source tools in information systems development

Over the past decade, the University of Navarra's academic management system evolved from a mainframe environment to windows-based client-server architecture and then to a Web environment. Aiming for independence from vendors, these developers adopted open-source solutions for their Web applications and were delighted with the results.     

Customer order management in service oriented holonic manufacturing

One of the most important problems when considering the design of manufacturing systems based on SOA paradigms is the integration of shop floor devices in the business processes at the enterprise level. This paper presents the design and implementation of the Customer Order Management (COM) module based on SOA architecture in the context of holonic manufacturing systems. The COM module is integrating with SOA enabled shop floor devices using industry standards. The implementation leverages a multi agent system suited for industrial applications integrated in a SOA environment capable of dynamic BPEL workflow generation and execution. The prototype consists in a SCA application for core COM module functionality and an extension for NetLogo MAS platform for SOA integration. The COM module interacts with the MES layer using real time events handled by the BPEL process implementation in the execution stage. A web based portal frontend for the COM module has been developed to allow real time tracking of customer orders, providing data about product batch execution and individual progress of each product on the production line.     

An ontology-based collaborative service-oriented simulation framework with Microsoft Robotics Studio®

In Service-Oriented Architecture (SOA), the concepts that services can be discovered and application can be composed via service discovery bring great flexibility to application development [Y. Chen, W.T. Tsai, Distributed Service-Oriented Software Development, Kendall/Hunt, 2008, [4]]. Microsoft Robotics Studio (MSRS) is a recent initiative in applying SOA to embedded systems and one of its key features is its 3-D simulation tool that allows applications to be simulated before deployment. This paper proposes an ontology-based service-oriented simulation framework with MSRS by adding a set of ontology systems, i.e., service ontology, workflow ontology, entity ontology, and environment ontology. These ontology systems store relevant information useful to compose simulation applications, and items stored also cross reference to each other to facilitate reusability and rapid application composition, This paper then provides a detailed case study on a popular robotic game Sumobot using MSRS to illustrate the key concepts and how they can support rapid simulation development.¹     

Mainframes, Cobol still popular

Mainframes have yet to prove obsolete in the corporate computing environment. Their demise, you might say, has been greatly exaggerated. Findings from a Cutter Consortium survey support this contention. More than half of the respondents still have major applications running on mainframes; a quarter have more than half of their critical applications on the mainframe     

Using architectural patterns and blueprints for service-oriented architecture

Using software patterns and blueprints to express a service-oriented architecture's fundamental principles supports the efficient use of SOA technologies for application development. Understanding SOA and all of its implications for software applications requires introducing a set of architectural principles that define SOA more concretely. Software patterns and blueprints can accommodate both forward and reverse engineering. Using the core SOA principles, software architects can derive best-practice pattern systems and catalogs that illustrate how to leverage existing SOA technologies.
