Reengenharia de Sistema de Informação

Abstract

This work was essentially motivated by the way the Ministry of Planning and Finance views the information systems component as an essential tool in the process of data manipulation and obtaining information for current management. The objective of this work is to apply the reengineering of the information systems existing in the National Directorate of Public Accounting, namely the “Number and Book Model 17 system, the Book Model 17 Audit system and the General State Account Preparation system. These systems, although conceived for a common purpose, were developed in different programming languages ​​and do not have automatic interconnection, which makes it difficult to obtain timely information for the extraction of final reports. For the purpose of reengineering, a method was used that allowed the survey of information systems to be carried out, including the assessment of effectiveness, efficiency and adherence to the established objectives. It was concluded that when the Reengineering of Information Systems was applied, it would be possible to obtain information at the right time, which will facilitate the obtaining of final reports in good time at the level of the National Directorate of Public Accounting of the Ministry of Planning and Finance .
