Software architecture of distributed client/server library circulation system

摘要

Purpose - The purpose of this paper is to model and implement software architecture forrntransparent communication of client and server sides of library circulation system in order to enablernsystem operation in different network configurations.rnDesign/methodology/approach - Object-oriented methodology and design patterns are used forrnmodeling system architecture. Modeling is carried out in the CASE tool that supports the UnifiedrnModeling Language (UML 2.0) by means of class and sequence diagrams. The implementation isrncarried out in the Java programming language using open source components.rnFindings - The result is a software package for transparent communication of client and server sidernof library circulation system. Database operations are executed through this package. The packagerncan execute the operations under different protocols, which enables the work of the library circulationrnsystem in the intranet and internet environments.rnResearch limitation/implications - The proposed software architecture and implementation arernintegrated into the circulation subsystem of the BISIS library information system and rely on thernHibernate package for object/relational mapping. For integration into other systems where operationsrnwould not be related to the database or would use some other ORM technologies, it would be necessaryrnto make corresponding changes in the implementation.rnPractical implications - The package is integrated, together with the library circulation system,rninto the fourth version of the BISIS system. Testing and verifying were carried out in public andrnspecial libraries.rnOriginality/value - Originality of the paper is to be found in the proposed software architecture thatrnis network-agnostic and facilitates transparent communication of client and server sides of therncirculation system while not imposing a single communication technology or protocol. Besides, thernarchitecture does not depend on the functionality of the circulation system and can be used forrndifferent purposes, and not only for communication with the database as presented in the paper.rnAdding new functionalities is simple and does not require changes in the existing program code.
