Análise e desenho do sistema de partilhas da Empresa Nacional de Portos e Caminhos de Ferro de Moçambique, E.E. CFM

Abstract

A he analysis of the System of Sharing of the National Company of Ports and Railways was based on SSADM - Structured Systems Analysis and Design Methodology. Given the characteristics current of the operation of this System did not follow the strict phasing that the methodology methodology requires. A methodology for the collection of information on this System, was based on interviews involving Directors, Heads of Department, Heads of Sector and Section, as well as technicians appointed for this purpose. Contacts were made with the Programming and Software Development Departments (of the Computer Services), Supervision (of the Commercial Department), among others, with the aim of getting to know all the Information that flows from the outside to the bodies (Departments), the entities involved, the frequency, the models used, as well as the periodicity, the models used and the regulatory standards standards (see attachments). After knowledge of the current system, a brief analysis was carried out of the models of the documents collected during the survey phase, in order to detect anomalies in the current system with regard to the documents documents produced, their circulation and analysis of requirements and definition of the solution. To to guarantee the quality of the results, a review was carried out after of each activity. The results of this study are: - Circuit showing documents entering and leaving the Current System and exiting the Current System; - Context Context Diagram showing the information flowing into and out of the Current and leaving the Current System and also showing the scope of the Sharing System Sharing System; - Data Flow Data Flow Diagrams to show the processes within the Current Data Flow Diagrams to show the processes within the Current System with the data flows; - Entity-Association Diagram of Entity-Association to show the information within the Current System; - Problem/Requirements List of problems/requirements to indicate the problems of the Current Current System's requirements; - Implementation implementation options of the Requested System showing the possible implementation options of the new System and the respective advantages and advantages and disadvantages of each option; Detailed definition of the Required System showing its detailed DFD's detailed and refined and the respective DEA and followed by CVE's of each entity; Recommendations and final conclusions.
