Abstract

The embodiment of the invention discloses an OLTP((on-line transaction processing)-based data modifying method and system as well as a graphic database server. The method comprises the steps that of: receiving a data modification command transmitted by a client side through calling an API (application programming interface). wherein the data modification command comprises a transaction identifier, a node name, a filtering condition and data to be updated; searching transaction records according to the transaction identifier, and adding the node name to the searched effective transaction record; searching a node attribute status information table according to the node name, and acquiring the data records meeting the filtering condition from the node attribute status information table; and updating the data records one by one by the data to be updated. By applying the data modifying and system as well as the graphic database server disclosed by the embodiment of the invention, the data record modification on multiple nodes related to one transaction can be realized, so as to guarantee the synchronism and the integrity of data modification; and when the transaction fails, data can be recovered through rollback operation so as to guarantee the integrity of a database.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data modification method, system and graph database server based on OLTP (On-Line Transaction Processing, online transaction processing system). Background technique [0002] OLTP is a system that collects and processes data associated with transactions in real time, as well as changes between shared databases and other files. When performing online transaction processing, the raw data to be processed can be immediately transmitted to the computing center for processing, and the processing results will be given in a very short time, so as to realize instant processing and instant response to the data. [0003] In an OLTP system based on a distributed environment, the integrity of the database needs to be maintained. In the prior art, due to the operational complexity of OLTP and the demand for fast input / output, most OLTP are implemented on large computer syst...
