DESIGNING A HETEROGENEOUS INFORMATION SYSTEM FOR PURCHASING MANAGEMENT IN AN ENTERPRISE
The process of designing a heterogeneous information system for procurement management at small and medium-sized businesses is considered. A detailed analysis of the business process of procurement management and ready-made solutions on the market is carried out. Based on the comparison, a decision was made to design the architecture of a heterogeneous information system using the NoSQL approach to developing the system’s databases. The advantages of using a non-relational approach to database development in comparison with the traditional relational approach are listed. A review of the non-relational database management system (DBMS) used is carried out. The client-server architecture of the application is described and arguments are given to justify its use.
