Methods for facilitating updating of data in a database by a data-access system in communication with the database and a client application. The methods include initiating updating transactions by the data-access system based on requests from the client application for obtaining a portion of the database using a predetermined obtaining protocol; generating transaction identifiers with identifier values in the data-access system upon the initiating of each updating transaction; assigning a transaction identifier or a predetermined transaction identifier to each obtained portion; modifying at least one of the obtained portions of the database based on instructions received from the client application; and forwarding said modified portions to the database based on the transaction identifier assigned to each modified portion. In this way, the overall efficiency of the data-access system in processing of the client updating requests can be advantageously increased.
