Data processing method and device based on cascade selector, equipment and medium

The invention provides a data processing method based on a cascade selector, and relates to the field of finance. The method comprises the steps of obtaining to-be-processed data from a user; a query method is called according to the to-be-processed data, a query request is sent to N data sources, the N data sources comprise total data with a cascade relation and lazy loading data sources independent of the cascade selector, and N is larger than or equal to 1; obtaining a first query result returned by the N data sources in response to the query request; and displaying the first query result on a query result interface of the cascade selector. The invention further provides a data processing device and equipment based on the cascade selector, a storage medium and a program product. 本公开提供了一种基于级联选择器的数据处理方法，涉及金融领域。该方法包括：获得来自用户的待处理数据；根据所述待处理数据调用查询方法，向N个数据源发送查询请求，所述N个数据源包括具有级联关系的全量数据，且独立于所述级联选择器的懒加载数据源，N大于或等于1；获取所述N个数据源响应于所述查询请求返回的第一查询结果；将所述第一查询结果显示在所述级联选择器的查询结果界面。本公开还提供了一种基于级联选择器的数据处理装置、设备、存储介质和程序产品。
