Problems solved by technology

The serializable technology and multiple concurrent access control technologies in the database field can only solve the problems related to transaction consistency, but cannot solve other consistency problems (for example, the consistency problem of shared data objects), so through serialization Technology, unable to detect some abnormal problems
That is to say, there are transactions that partially meet the serializability requirements but still have exceptions, which cannot be detected by the serializable scheduling technology, that is, transactions consistent with other consistency (for example, shared data object consistency ) data abnormality problem, which cannot be identified, and the accuracy of system status detection is low

Abstract

Embodiments of the invention disclose a database-based data processing method, apparatus and device, and a readable storage medium. The method comprises the steps of obtaining a first transaction anda second transaction for a database; determining a target partial order relationship between the first transaction and the second transaction in a first configuration partial order relationship and asecond configuration partial order relationship; wherein the first configuration partial order relation refers to a partial order relation defined based on shared operation data items, and the secondconfiguration partial order relation refers to a partial order relation defined based on affairs; based on the target partial order relationship, constructing a transaction directed graph containing the first transaction and the second transaction; and detecting a consistency state between the first transaction and the second transaction according to the transaction directed graph. By adopting themethod and the device, the accuracy of exception detection on the transaction system can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a database-based data processing method, device, equipment and readable storage medium. Background technique [0002] Data processing technology requires the semantics of transactions and borrows the four ACID characteristics of relational databases to ensure the transaction characteristics of the system to meet the needs of electronic transactions. Among them, A is atomicity, C is consistency, I is isolation, and D is persistence. Electronic transaction operations require these four characteristics to ensure the safety and reliability of transactions. Distributed transaction processing technology also needs to meet the four ACID characteristics of transactions. In order to meet the four ACID characteristics, data processing technology needs a variety of technologies to guarantee, the most important of which is data consistency and isolation. Among them, data consist...
