The Design And Implementation Of HUATAI SECURITIES’s Real-time Estimation System

Some financial products,such as funds,trusts,etc.,will buy the stock for asset allocation.The net values of these products will be announced after the end of the trading day and people can not the get the net value of the product in real time.People need the net values of products in real time as an investment reference.So we develop the Huatai Securities’s Real-time Evaluation System to provide the real-time net values of products.The System consists of two parts:the software developed with Java and script.The main function of the software is the visual control and configuration.The Java program is divided into presentation layer,business logic layer and database access layer.Presentation layer uses the Java swing,business logic layer uses the kettle and the log4j and database access layer uses the JDBC and the Oracle 11 g.Files’ storage uses the Java.Properties file.The other part is composed of the kettle file and the Oracle stored procedure,and its main function is data extraction and calculation.When the method of calculation changes,there is no need to modify the Java program.We can modify the kettle script and Oracle stored procedures to achieve new requirements.This design enhances the flexibility,scalability and configurability of real-time evaluation systems.The system is now in use,you can see the real-time valuation of the fund’s products in the app named Huatai Securities.Because the system can not get the data of OTC in real time,some products will have some deviation in real-time valuation at some time.
