The growth of the Organization’s data collections, due to the development of new materials and advanced computing devices, puts the database (Db) technology at the forefront. Conse‐ quentially to its popularity, different options of database management systems (DBMS) can be found on the market to store one of the most important Organization’s assets, the data. Among the factors that may influence its choice (advanced features, interoperability, etc.), could be highlighted the cost-benefit provided by fierce competition between different software philosophies – proprietary (Oracle, MS SQL Server, IBM DB2, etc.) and public domain (PostgreSQL, MySQL, Firebird, etc.) – and, also the system performance in critical computing environments.
