Choosing the optimal database system to create a CRM system


MSSQL, MySQL and PostgreSQL are some of the most popular databases. The selection of the database for the creation of a CRM system is based mainly on the assessment of its effectiveness in terms of speed. The article aims to choose the optimal database system to create an effective CRM system. The literature review led to the hypothesis that MSSQL will be the fastest. A series of experiments using the app served as a test. During the research, a series of experiments were carried out using the order processing module, which is part of a larger CRM system aimed at the e-commerce industry. Each query was measured 10 times, the result averaged. The research results did not confirm the hypothesis about the speed and significant advantage of the MSSQL database. The results showed the advantage of PostgreSQL over other databases.
