Abstract

The invention discloses a stock selection control method, device and system based on data classification processing. The method comprises the steps of obtaining a stock selection request; extracting a plurality of strategy factors from the stock selection request, and splitting the stock selection request into a static data stock selection request and a calculation data stock selection request based on the strategy demand of each strategy factor; obtaining a static data stock result set based on the static data stock selection request, and obtaining a calculation data stock result set based on the calculation data stock selection request; and performing merging processing on the static data stock result set and the calculation data stock result set to form an output stock result set, and returning the output stock result set to the request terminal sending the stock selection request. According to the invention, the stock selection data is divided into the static data stock result set and the calculation data stock result set for classified storage and scheduling, and the calculation data stock result set is divided into primary storage and secondary storage, so that the processing speed and the processing precision of the stock selection request are effectively improved, and more objective and high-accuracy stocks can be recommended for users.
