| Abstract [eng] |
Nowadays, while working with large amount of information the most important moment is the time of the beginning of the required material search. However, many emerging systems are usually developed as if it could work with small amounts of information which increases during a long time of maintenance. The response time to queries tend to slow down and the scientists are looking for the modern ways to optimize the systems due to that. In order to optimize all the internet applications the modern search is being carried out to find the best receipt and the optimal technological systems are implemented to enhance the systems productivity. The study of the RDBMS is used to find an answer to the question of optimization. This work aims at analyzing the comparison of the principles of the concerned database management systems operation and the evaluation of the speed of the work with data. Trying to fulfill the main aim of the research three tasks are set, which are successfully accomplished and let to make the revealing conclusion. The conclusion has been made that in Windows server Apache the best PHP database extensions is such as PDO mysql. Also, it is found that for the MSSQL database is suitable to use PDO mssql extension to PostgreSQL - PDO pgsql extension, and with Oracle - oci8 extension. |
