Problems solved by technology
In the existing technology, the support method for label construction is to aggregate the data of each source system to the target data platform through ETL, then copy it to the target data platform, and then carry out label construction. This mode of label construction data replication and synchronization consumes a lot of system storage resources, resulting in Data redundancy reduces the efficiency of label query, and this kind of label construction mainly uses offline data, which has poor timeliness
In addition, the label construction method in the existing technology only supports access to a single data platform, which cannot meet the needs of label construction and cross-database data combination query for cross-platform data in a big data environment

The embodiment of the invention provides a label query method and device. The method includes: receiving a label query request, generating a label query plan according to the label query request, andparsing and splitting the label query plan according to data, which are stored by multiple data platforms, to obtain multiple label query sub-plans; acquiring types of the multiple data platforms, which correspond to the multiple label query sub-plans, according to pre-stored definition information of label data, and generating multiple query commands according to the multiple label query sub-plans and the multiple data platforms; sending the corresponding query commands to the multiple data platforms through query interfaces, which correspond to the multiple data platforms, to enable the dataplatforms to execute corresponding query tasks according to the query commands; and receiving multiple query sub-results sent by the multiple data platforms, carrying out aggregation association calculation on the multiple query sub-results to obtain query results, and outputting the same. The device is used for executing the above-mentioned method. The embodiment of the invention realizes cross-platform label queries.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of data services, and in particular to a tag query method and device. Background technique [0002] Tags are based on the aggregation and integration analysis of customer basic attributes, behavior characteristics, business preferences and other user information, behavior data, order data, and location data. Based on business rules, customer characteristics are re-described in a natural language-like manner, for example: Senior white-collar workers, campus customers, Jay Chou fans, stock investors, potential customers of 4G terminals. Effectively characterizing and utilizing label information can not only fully grasp customer attributes, perceive changes in customer behavior, support daily operations, precise marketing and customer service, but also support the expansion of business models, and explore and open up new markets for the future. The label library is a system that carri...
