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 embodiment of the present invention relates to the technical field of data services, and specifically relates to a label query method and device. Background technique [0002] Labeling is based on the aggregated and integrated analysis of user information, behavioral data, ordering data, and location data such as basic customer attributes, behavior characteristics, and business preferences. Based on business rules, it uses natural language-like methods to re-describe customer characteristics, such as: Senior white-collar workers, campus customers, Jay Chou fans, stock investors, 4G terminal potential customers. Effectively portraying and using label information can not only fully grasp customer attributes, perceive customer behavior changes, support daily operations, precise marketing and customer service, but also support the expansion of business models, and explore and open new markets for the future. The tag library is a system that carries tag man...
