Design Structure Essay, Research Paper

Basic thoughts and Concepts of Software DesignAn Interface to the End-UserThe Project Management System was designed with the end that the end-user can manage the system on his own.The synergistic user interface is based on the Windows interface.The interface plans use standard package of the market like Visual Basic, Microsoft Access and Crystal Reports.DocumentationThe package should be documented. The certification should cover: h Description of the database architecture h Analysis of the plans h Analysis of the studies h Description of processs h User & # 8217 ; s steer for the user plan H Set-up from the bing systemThe certification can be done in French or English, except the user & # 8217 ; s ushers which should be done in French.ModularityThe bundle consists of the undermentioned functional faculties: H Data input of timesheets h Data input on Freelancer Costss h Data input of Other Costss h Job-book h Administration of the Project Accounting h Importation from General Accounting H Importation from Freelance Payroll h Importing from Estimates h Project Accounting describing H Project Trade ReportingEach of these functional faculties or units is provided with one or more programs.The faculties of informations direction and coverage are clearly separated.Database orientationThe package is database oriented. It uses the client-server engineering. The Database Management System used is Oracle.information is alone and can be more safety controlled.IntegrationBecause of the database orientation, information is alone and can be more safety controlled. The relational database technique allows to pull off the dealingss between the different information. A conceptual theoretical account provides a good wiew and a good control of the whole information. This conceptual theoretical account is managed by a dedicated package ( AM

C Designor ) .

FlexibilityA flexible package id a package easy to administer, to keep and to modify. It & # 8217 ; s possible because of the rules of modularity and the database orientation. It & # 8217 ; s besides helped by a good certification and a package to pull off the conceptual model.The system should let to modify some man-day charges, unit & # 8217 ; s monetary value of cost-center, overhead rate for a past period without to hold to modify all the corresponding yesteryear costs.EvolutivityThe system should be able to hold developments ( functional and technique ) . It should non be linked to the construction of the company. Again It & # 8217 ; s possible because of the rules of modularity and the database orientation. It & # 8217 ; s besides helped by a good certification and a package to pull off the conceptual model.The system should non be limited to some versions of runing systems, or database direction systems or others software.Control of AccessThe entree to the different faculties, and within them, to the different functionnalities is control in map of the user and of the rights he has for the Oracle tabular arraies and the Access objects.Self CheckingA self-checking system is considered as of import in order to accomplish a high dependability of the calculations involved and the proficient public presentation of the system. The checking is done on three degrees: H Data entry: every entry is checked instantly with respects to existance of undertakings codifications, histories etc. h Importing: every file imported is checked h Processing Data: every computation cheque informations integritySecurityThe safety of the systems is warranted by day-to-day backup.Year 2000The system should be 100 % Y2K compliant.Evolution with the EuroThe system should be build to let a migration from the local currency ( the Franc ) to the Euro. The rule leting it is to duplicate all the information in the database.
