Development of an information system for testing students’ knowledge using Delphi and MS SQL Server

Testing students is one way to verify their knowledge. Any person, one way or another, meets with the passage of tests related to his professional activities, training or re-certification. Of course, tests are a serious psychological strain on the subjects, especially in conditions of limited testing time and the number of attempts. Therefore, the actual question is: how to properly organize testing to obtain the maximum positive effect. For comparison: in order to pass the professional tests Microsoft or Oracle companies to receive the certificates of experts or professionals in software these companies need to respond to 75% of the questions correctly. Moreover, the delivery of such tests is carried out in specially equipped, isolated rooms, in the complete absence of mobile phones, tablets, iPads and other similar means. Having tried various methods of testing, the author, having considerable professional experience in the field of programming and creating users’ workplaces, decided to develop a testing system on his own. Software development for testing was carried out using the RAD programming environment Embarcadero Delphi, which made it possible to create an interface convenient for the end user. The main business logic of the testing system was implemented as Microsoft SQL Server stored procedures, which ensured high performance, system scalability and reliable information protection from unauthorized access.
