As described in the background, metadata corresponding to data may change during the product and project lifecycle due to changes in demand or other factors. At present, only the change of data is recorded, an effective method is not available for recording the change of metadata, and the change of the metadata cannot be traced safely and effectively, so that the problems of information distortion and the like of the data in development and maintenance are caused.
Therefore, the application provides a method for recording metadata, when metadata corresponding to at least one type of data in business data changes, version attributes corresponding to the metadata are changed, each type of data corresponds to one type of metadata, the version attributes are used for representing whether the metadata corresponding to each type of data in the business data changes, and then the change condition of the metadata is obtained according to the changed version attributes. Therefore, when the metadata corresponding to one kind of data in the service data changes or the metadata corresponding to various kinds of data in the service data changes simultaneously, the version attribute of the metadata changes correspondingly, so that the metadata corresponding to one kind or several kinds of data in the service data can be known to change according to the change of the version attribute, the change condition of the metadata can be obtained according to the changed version attribute, and the change of the metadata can be traced safely and effectively.
In order to facilitate understanding of the technical solutions and effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, in step S01, when metadata corresponding to at least one type of data in the service data changes, a version attribute corresponding to the metadata is changed; each kind of the data corresponds to a kind of metadata; the version attribute is used for representing whether metadata corresponding to each piece of the business data changes.
In the embodiment of the present application, the service data includes a plurality of types of data, such as table data, field data, and the like, each type of data corresponds to one type of metadata, and one type of data includes a plurality of types of data, each type of data has metadata corresponding to the data. The version attribute is used for representing whether metadata corresponding to each type of data in the service data changes. When metadata corresponding to one type of data changes or metadata corresponding to multiple types of data respectively changes at the same time, version attributes corresponding to the metadata are changed, it can be understood that the version attributes corresponding to the metadata change once every time the metadata corresponding to the data in the service data changes, and the change of the metadata corresponding to the data at this point can be a change of metadata corresponding to multiple types of data respectively in one type of data in the service data at the same time, or a change of the metadata corresponding to one type of data in the service data. Data comprising at least one of: a field english name, a field chinese name, a field type, a field length, a partition type, a field mode type, a decimal place, whether null, a sequence number, a default value, whether primary key, a field description, a status, a version, a creator, a creation time, an updater, an update time, and remarks.
Referring to table 1, when data is field data, table 1 shows metadata corresponding to a plurality of data in a field, and the metadata corresponding to an english name of the field is CUST _ NO; metadata corresponding to the field Chinese name is a core client number of the mobile banking; the metadata corresponding to the field type is VARCHAR; the field length corresponds to 16 metadata; the metadata corresponding to the partition type is a day; the metadata corresponding to the field mode type (discrete-0 or continuous-1) is 1; the metadata corresponding to the decimal point digit is NULL; whether the metadata corresponding to the null is 0; the metadata corresponding to the sequence number is 1; the metadata corresponding to the default value is 1; whether the metadata corresponding to the primary key is Y; the field describes that the corresponding metadata is a core client number of the mobile banking; the metadata corresponding to the state is 1; the metadata corresponding to the version is 1.0.1; the creator corresponds to metadata of 80956849186447dd926385031d90b 048; the metadata corresponding to the creation time is 2019-10-0212:45: 00; the updater corresponding metadata is 80956849186447dd926385031d90b 043; the metadata corresponding to the updating time is 2019-10-0212:45: 00; and the metadata corresponding to the remarks is the core client number of the remark bank.
Table 1 when data is a field, metadata corresponding to the data in the field respectively
Referring to table 2, the metadata corresponding to the field length changes from original 16 to 20, and correspondingly, the metadata corresponding to the version attribute also changes from 1.0.1 to 1.0.2.
TABLE 2 metadata corresponding to data in a field when the metadata changes
In step S02, a change condition of the metadata is acquired based on the modified version attribute.
In this embodiment, the metadata corresponding to the modified version attribute is obtained according to the modified version attribute, so as to know the change condition of the metadata. And acquiring corresponding metadata according to different version attributes, for example, the metadata comprises the metadata corresponding to the initial version attribute and the metadata corresponding to the version attribute after the metadata changes continuously, and then acquiring the change condition of the metadata.
In this embodiment, since the ID of the metadata is fixed and unchangeable, the modified version attribute may be obtained according to the ID of the metadata, that is, the original version attribute and the plurality of changed version attributes may be obtained according to the ID of the metadata, so that a plurality of different version attributes may be obtained, then the metadata corresponding to each of the different version attributes may be obtained, and the metadata of the data in each of the different metadata may be compared, so that the change condition of the metadata may be known.
The method for recording metadata provided in this embodiment of the present application is described in detail above, and when metadata corresponding to at least one type of data in business data changes, a version attribute corresponding to the metadata is changed, where each type of data corresponds to one type of metadata, and the version attribute is used to represent whether the metadata corresponding to each type of data in the business data changes, and then, a change condition of the metadata is obtained according to the changed version attribute. Therefore, when the metadata corresponding to one kind of data in the service data changes or the metadata corresponding to various kinds of data in the service data changes simultaneously, the version attribute of the metadata changes correspondingly, so that the metadata corresponding to one kind or several kinds of data in the service data can be known to change according to the change of the version attribute, the change condition of the metadata can be obtained according to the changed version attribute, and the change of the metadata can be traced safely and effectively.
