The pros and cons of using SDL for creation of distributed services

In a competitive market for the creation of complex distributed services, time to market, development cost, maintenance and flexibility are key issues. Optimizing the development process is very much a matter of optimizing the technologies used during service creation. This paper reports on the experience gained in the Service Creation projects SCREEN and TOSCA on use of the language SDL for efficient service creation

Information System of the Firm "Cyklosport Pavka"

Tato práce se zabývá tvorbou modulárního informačního systému na základě požadavků zadavatelské firmy. Systém je implementován pomocí jazyka Delphi 2007 a PHP5, postavených nad databázemi Interbase 2007 a MySQL 5. Cílem práce je vytvořit funkční prototyp informačního systému, skládajícího se z modulu pro řízení skladu, modulu pro řízení práce servisní dílny a modulu pro internetový obchod. Návrh tohoto systému je popsán pomocí prostředků modelovacího jazyka UML. V hlavní části práci je pak rozebírána implementace jednotlivých modulů.This thesis is concerned with creation of modular information system on the basis of submitter firm's requirements. The system is implemented by using Delphi 2007 and PHP5, built on databases Interbase 2007 and MySQL 5. It's aim is create functional prototype of information system, consisting of program unit for inventory control, program unit for managing service shop and program unit for e-shop. Design of this system is described using UML language. Core of the thesis is formed of implementation analysis of each single program unit.

Framework for Product Lifecycle Management integration in Small and Medium Enterprises networks

In order to improve the performance of extended enterprises, Small and Medium Enterprises (SMEs) must be integrated into the extended networks. This integration must be carried out on several levels which are mastered by the Product Lifecycle Management (PLM). But, PLM is underdeveloped in SMEs mainly because of the difficulties in implementing information systems. This paper aims to propose a modeling framework to facilitate the implementation of PLM systems in SMEs. Our approach proposes a generic model for the creation of processes and data models. These models are explained, based on the scope and framework of the modeling, in order to highlight the improvements provided

Semi-automatic distribution pattern modeling of web service compositions using semantics

Enterprise systems are frequently built by combining a number of discrete Web services together, a process termed composition. There are a number of architectural configurations or distribution patterns, which express how a composed system is to be deployed. Previously, we presented a Model Driven Architecture using UML 2.0, which took existing service interfaces as its input and generated an executable Web service composition, guided by a distribution pattern model. In this paper, we propose using Web service semantic descriptions in addition to Web service interfaces, to assist in the semi-automatic generation of the distribution pattern model. Web services described using semantic languages, such as OWL-S, can be automatically assessed for compatibility and their input and output messages can be mapped to each other

Distribution pattern-driven development of service architectures

Distributed systems are being constructed by composing a number of discrete components. This practice is particularly prevalent within the Web service domain in the form of service process orchestration and choreography. Often, enterprise systems are built from many existing discrete applications such as legacy applications exposed using Web service interfaces. There are a number of architectural configurations or distribution patterns, which express how a composed system is to be deployed in a distributed environment. However, the amount of code required to realise these distribution patterns is considerable. In this paper, we propose a distribution pattern-driven approach to service composition and architecting. We develop, based on a catalog of patterns, a UML-compliant framework, which takes existing Web service interfaces as its input and generates executable Web service compositions based on a distribution pattern chosen by the software architect
