| Abstract [eng] |
Database is one the main object in the informatics systems, which is usually realized relational database management systems (DBMS) basis. In order to achieve similar functionality and performance of desktop systems for informational mobile system we have to choose a suitable data synchronization method. This work investigates the exchange of data between the DBMS and the mobile device and methods of determining factors for their choice. In this task are pending tasks: analyze the data exchange between the DBMS and the mobile device and methods of formulating the criteria that determine the decision-making, the choice of data-exchange method; allow the exchange of data between the DBMS and the mobile device choice process. According to the literary analysis criteria were formulated, which affect the choice of methods for data exchange between the remote DBMS and the mobile device. According to the criteria were made data exchange methods for the choice process. The process provides the graphical notation with the accompanying detailed description. Additionally, the work carried out in remote data access and direct remote database using data exchange methods for the experimental performance research. For experiments were designed and developed software. The research was conducted using a set of 5 database tables and data operations which processed from 100 to 100 000 entries in one transaction. Experiment helped to establish two further criteria, which leads to the exchange of data between the DBMS and the mobile device selection method. These criteria were added to the proposed data exchange process. The proposed process, if necessary, can be extended IS developers. |
