Embodiment Construction

[0016] Referring now to the accompanying drawings, in particular figure 1 , describes a distributed data processing system 100 that may be used to implement the present invention. Distributed data processing system 100 includes network 102 , which is the medium used to provide communication links between computers within distributed data processing system 100 that are connected together.

[0017] In the depicted example, server 104 is connected to network 102 along with storage 106 . Additionally, clients 108 , 110 and 112 are also connected to network 102 . Distributed data processing system 100 may include additional servers, clients, and other devices not shown. In the depicted example, distributed data processing system 100 is the Internet, and network 102 represents a collection of networks and gateways that communicate with each other using the TCP / IP suite of protocols. Of course, the distributed data processing system 100 can also be implemented as different types o...

Abstract

The invention provides a method and device for detecting abnormal data records. The method comprises the following steps: excavating a data rule from a verified data record set according to an excavation rule; and verifying the data records in an unverified data record set according to the excavated data rule, and determining the data records which do not meet the excavated data rule as the abnormal data records.

Description

technical field [0001] The present invention relates to database systems, and more particularly to methods and apparatus for detecting anomalous data records. Background technique [0002] In a database application system, it is often necessary to test whether the application system can run normally with respect to existing data records in the database. In the case of a large number of data records, it is difficult to test each data record. Therefore, it is necessary to select a part of representative data records for testing. [0003] For example, in data migration, data in one system (hereinafter referred to as source system) is imported into another system (hereinafter referred to as target system) according to migration rules. But during data migration, due to limited time and / or resources, it is almost impossible to write completely correct migration rules. Therefore, in many cases, even if the migration rules are strictly followed to migrate data, there is still no ...
