Abstract

The embodiment of the invention discloses an on-line transaction processing (OLTP)-based data deletion method, an OLTP-based data deletion system and a graphic database sever. The method comprises the following steps of: receiving a data deletion command transmitted by calling an application programming interface (API) through a client, wherein the data deletion command contains transaction identification, node name and filter condition; searching transaction record according to the transaction identification, and adding the node name into the searched valid transaction record; searching a node attribute state information table according to the node name, and acquiring data records in accordance with the filter condition from the node attribute state information table; and deleting the data records in accordance with the filter condition item by item. By using the embodiment of the invention, deletion of the data records of one transaction on multiple nodes can be realized, and synchronism and integrity of data deletion can be ensured; and when the transaction is invalid, data recovery can be performed by rollback operation, and the integrity of the database is ensured.

Description

technical field

[0001] The present application relates to the technical field of data processing, in particular to a data deletion 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 systems....
