Method and apparatus for detecting changed data

An apparatus for detecting changed data, the apparatus comprising:

• a memory and a processor coupled to the memory, the processor being configured to:
• record change status information of each data field in a data table during a version change, the version change including a change in data involved in at least one of programs, codes, resources, and test contents;
• record, according to the change status information, the number of times that a second data field being changed at the same time when a first data field is changed, comprising:
• outputting a change matrix table according to the change status information, wherein an element of the ith column of the jth row of the change matrix table indicates the number of times that the jth second data field being changed at the same time when the ith first data field is changed, or an element of the jth column of the ith row of the change matrix table indicates the number of times that the jth second data field being changed at the same time when the ith first data field is changed, wherein i and j are integers not less than 1;
• dividing the number of times that the second data field being changed at the same time when the first data field is changed by the number of times that the first data field is changed, to obtain a confidence probability of the second data field being changed at the same time when the first data field is changed;
• determine, when confidence probabilities of at least two second data fields being changed in the same first data field being changed are greater than a confidence probability threshold of the data table, that the second data fields corresponding to the confidence probabilities greater than the confidence probability threshold are a combined field;
• determine whether the combined field matches a combined field template during the version change;
• and
• identify a location in the data table where the combined field does not match the combined field template during the current version change so as to determine whether a data field is changed unnecessarily or a change of the data field is mistakenly missed during the version change, thereby reducing manual inspection and improve data inspection efficiency.

A non-transitory computer readable storage medium having stored therein one or more instructions, which, when executed by a computing device, cause the computing device to:

• record change status information of each data field in a data table during a version change, the version change including a change in data involved in at least one of programs, codes, resources, and test contents;
• record, according to the change status information, the number of times that a second data field being changed at the same time when a first data field is changed, comprising:
• outputting a change matrix table according to the change status information, wherein an element of the ith column of the jth row of the change matrix table indicates the number of times that the jth second data field being changed at the same time when the ith first data field is changed, or an element of the jth column of the ith row of the change matrix table indicates the number of times that the jth second data field being changed at the same time when the ith first data field is changed, wherein i and j are integers not less than 1;
• dividing the number of times that the second data field being changed at the same time when the first data field is changed by the number of times that the first data field is changed, to obtain a confidence probability of the second data field being changed at the same time when the first data field is changed;
• determine, when confidence probabilities of at least two second data fields being changed in the first data field being changed are greater than a confidence probability threshold of the data table, that the second data fields corresponding to the confidence probabilities greater than the confidence probability threshold are a combined field;
• determine whether the combined field matches a combined field template during the version change;
• and
• identify a location in the data table where the combined field does not match the combined field template during the version change so as to determine whether some data fields are changed unnecessarily or changes of some data fields are mistakenly missed during the version change, thereby reducing manual inspection and improve data inspection efficiency.
