Embodiments of the invention provide a kind of method of obtaining data fast, and are as shown in Figure 1, specifically may further comprise the steps:
First trigger messages that step s101, terminal receiving control system send;
Wherein, said first trigger messages is meant when data file changes, the file change information that said control system is sent to said terminal.The function that control system utilizes Windows api function that Windows provides to concentrate is realized the monitoring to the data file, Windows api function collection be a cover each parts of being used for controlling Windows outward appearance and behavior one overlap predefined Windows function.The monitoring of using these functions that the data file is implemented; When data file such as is created, is modified, delete at the incident of operating; Function all can have corresponding reaction to incident; Produce file change information, and send to the terminal and the data file that changes is in time handled to remind the terminal.
Whether step s102, said terminal judges have in the data dictionary table and the said first trigger messages identical triggering message, if get into step s103; If not, get into step s104.
Step s103 deletes said first trigger messages;
Step s104 is saved in said first trigger messages in the said data dictionary table, launches clock simultaneously, is used to set t time delay;
Wherein, data dictionary is meant that data item to data, data structure, data stream, data storage, processing logic, external entity etc. define and describe, and its objective is each element in the data process flow diagram is made detailed explanation.Data dictionary is that a kind of user can the accessed record database and the catalogue of application program source data.The active data dictionary is meant that its content can be by the automatic data updated dictionary of DBMS when database or application structure are made amendment.Passive data dictionary is meant must the manual data dictionary that upgrades its content when revising.Data dictionary is the tables of data that one group of data is made explanations, and the data dictionary table is the tables of data that the data in the tables of data are made explanations.The trigger messages that file change of storage produces in the data dictionary, the trigger messages that the data of storing a plurality of files in the data dictionary table produce when changing.Concrete application is above-mentioned active data dictionary in the embodiment of the invention, just when data file changes, can trigger messages be saved in the data dictionary table automatically.
