Method and device for accessing data entity

The invention discloses a method for accessing data entity, so as to achieve an objective of improving operation efficiency of a system. The method comprises: responded to a plurality of received access requests for data entity, returning to analog data entity aimed at the access requests, and executing parallel access on actual data entity corresponding to the analog data entity, wherein the analog data entity is internally provided with asynchronous thread, the asynchronous thread being used to obtain contents of the actual data entity when the actual data entity corresponding to the analog data entity is accessed, and load the contents of the actual data entity into the analog data entity; when a call aimed at the analog data entity exists, determining whether the contents of the actual data entity is loaded in analog data entity; if not, returning to the step of determining whether the contents of the actual data entity is loaded in analog data entity; and if yes, returning the analog data entity to be used for calling. In addition, the embodiment also provide a device for for accessing data entity.
