Method and device for realizing Bitmap-based user portrait construction by using Dores

The embodiment of the invention provides a method and device for realizing Bitmap-based user portrait construction by using Dores, and the method comprises the steps: obtaining user portrait basic information of a target platform in a preset time period, and synchronizing the user portrait basic information to a Dores environment through a real-time synchronization tool; the method comprises the following steps: loading user portrait basic information through a predesigned primary key data model and a predesigned detail data model in a Dores environment; based on the basic information of the user portrait, carrying out set loading on the basic information of the user portrait by adopting a Bitmap data type through an aggregation model of a Bitmap standard; basic information of the user portrait is processed, user ID information in the basic information is processed into a Bitmap data type, and label information is longitudinally expanded; and when the basic information of the user portrait loaded through the
