Embodiment
A kind of information merging method provided by the invention, be applied to comprise the system of the original data storage unit, centre data storage unit, merger data storage cell, temporary data storage unit, data buffer unit and the user terminal that are used for storing raw data more than, the core concept of this method is to obtain the raw data in a plurality of original data storage unit and the data of obtaining are carried out merger, deposit the data after the merger in the centre data storage unit, directly visit this centre data storage unit in the time of need obtaining data.
Referring to Fig. 1, the step of a kind of information merging method provided by the invention comprises:
101, user terminal obtains raw data in the mode that reads in batches by multithreading from the original data storage unit;
102, user terminal carries out merger with the described raw data of obtaining;
In this step, at first, user terminal is removed the data in merger data storage cell and the data buffer unit, in the merger data storage cell, set up a merger tables of data for each original data storage unit, the field of this merger tables of data comprises all fields and the merger tag field in the corresponding original data storage unit, the original data storage that to obtain from the original data storage unit and is initialized as not merger with the merger tag field content of this merger tables of data in the merger tables of data of correspondence;
Then, the merger tag field content modification of the data that user terminal is identical with major key content in the temporary data storage unit with major key content in the described merger tables of data is merger;
Then, user terminal is set up tables of data in data buffer unit, the field of this tables of data comprises all fields in the merger tables of data, according to predefined merger rule the data storage in the described merger tables of data is arrived described tables of data again, described merger rule comprises increment merger or brand-new merger, if predefined merger rule is the increment merger, the data storage that then with merger tag field content in the described merger tables of data is not merger is to described tables of data, if predefined merger rule is brand-new merger, then all data storage in the described merger tables of data are arrived described tables of data;
Next, user terminal is data with predefined operation rule and merger field with all aggregation of data that satisfy operation rule in the described tables of data, and other field contents beyond the merger field superpose as the content of field after the merger; Satisfy all data of operation rule as the data that are merged with described, the merger tag field content of the described data that are merged is set to merger in the merger data storage cell, and with merger tag field content in the merger data storage cell be the data storage of merger to temporary data storage unit, described data that are merged of deletion in data buffer unit at last;
Described predefined operation rule comprises equal merger, comprises merger or equals merger, equating wherein that merger is meant carries out merger when having the identical data of two above merger field contents in the described data buffer unit, the merger step is: with described two identical aggregation of data of above merger field contents is data, and other field contents beyond the merger field superpose as the content of field after the merger; Comprise and carry out merger when merger is meant the data that exist two above merger field contents all to comprise a certain certain content in the described data buffer unit, this certain content is imported by the user, the merger step is: the aggregation of data that described two above merger field contents are all comprised a certain certain content is data, and other field contents beyond the merger field superpose as the content of field after the merger; Equaling merger is meant in the described data buffer unit and carries out merger when existing two above merger field contents to be equal to the data of a certain certain content, this certain content is imported by the user, the merger step is: the aggregation of data that described two above merger field contents are equal to a certain certain content is data, and other field contents beyond the merger field superpose as the content of field after the merger.Described merger field is any field in the predefined original data storage unit;
103, the data storage after the merger in the above-mentioned data buffer unit is arrived the centre data storage unit.
When needs obtain data from more than one original data storage unit, directly visit the centre data storage unit, from this centre data storage unit, obtain data.
