Abstract
A process for the retrieval and transfers of massive data between systems provides a process for the retrieval of massive data between applied systems and pagination display. The invention transfers by diminishing the searching parameter based on the Web Services, preserves and validates the enquiring condition with stochastic summarization, and has the features of high efficiency, good security and sustaining pagination display and examination.
Description
Technical field
The present invention relates to retrieval and transfers of massive data between a kind of system.
Background technology
Carrying out data passes between the different software application system is to realize information resources exchange and the basis of sharing.At present, mainly realize exchanges data between the different application systems by dual mode, the one, solve by open database, the target application system directly opens the access rights of own Database Systems to application system; The 2nd, come information transmission between the realization system by WEB SERVICES method.The advantage of preceding a kind of method is flexible operation (can realize the paging query display), access efficiency height, and shortcoming is dangerous, gives other application systems by exposing access rights, and software systems its data safety and integrality will be subjected to danger.The advantage of second method is the safety that has guaranteed the target application system database preferably, but shortcoming is that underaction (can't realize the paging query display), efficient are lower, can't satisfy the access transport of mass data between system.
Summary of the invention
Purpose of the present invention just provides a kind of safe, efficient, flexible, can realize the paging query display, and is realizing retrieval and transfers of massive data between mass data visit and system for transmitting between different application systems.
Retrieval and transfers of massive data between system of the present invention may further comprise the steps:
The search condition that step a, application system are transmitted encryption by the mode of Web Services is given goal systems;
Step b, goal systems receive application system and pass the Web Services information of coming, and the deciphering search condition is resolved search argument;
Step c, goal systems generate a random number with random function, and goal systems deposits the search argument of this random number and parsing in buffer memory or the database in as key-value pair;
Steps d, goal systems are retrieved according to search condition, generate result set, and goal systems returns to application system to above-mentioned random number and result set generation XML format string;
Step e, application system show Query Result, then send above-mentioned random number and new start-stop row number to goal systems if any page turn over operation;
Step f, the target application system obtains search argument according to above-mentioned random number, and amalgamation start-stop row number, re-executes query manipulation and returns to application system.
Retrieval and transfers of massive data between system of the present invention has following characteristics:
1, at first search argument only sends once, just can with random number and start-stop row number advance ground search operaqtion, transmit content for the search argument degree of safety than fail safe and minimizing that the inquiry of higher and complicated (as the irregular parameter of GIS) can increase transmission course so thereafter;
2, increased the retrieval authentication function, owing to just use random value to carry out query manipulation later in primary retrieval, whether goal systems can be differentiated according to random value and carried out like this;
3, increased page-turning function for the data retrieval between system;
4, guaranteed the property quoted once more of Query Result, because random value and Query Result keep, so, then can inquire about once more at any time according to random value if end value is used in other place in buffer memory or database.

Embodiment
Retrieval and transfers of massive data between a kind of system may further comprise the steps:
The search condition A (search argument X, start-stop row N are to M, and wherein querying condition can be very complicated) that step a, application system are transmitted encryption by the mode of Web Services gives the target application system;
Step b, target application system receive application system and pass the Web Services information of coming, and deciphering search condition A resolves search argument X, and start-stop row N is to M;
Step c, target application system generate a random number Y with random function, and the target application system is (Y X) deposits in buffer memory MAP or the database as key-value pair;
Steps d, target application system are retrieved according to search condition (X, N is to M), generate result set S, and the target application system returns to application system to Y and S generation XML format string;
Step e, application system show (N is to the M) of Query Result, if any page turn over operation then to the transmission Y of target application system and new start-stop row N to M;
Step f, target application system obtain search argument X according to Y, and amalgamation start-stop row N re-executes query manipulation and returns to application system to M.
Claims (1)
1, retrieval and transfers of massive data between a kind of system is characterized in that: may further comprise the steps:
Step a, application system transmit the search condition (A) of encryption by the mode of Web Services, and search argument (X), start-stop row number (N) are given the target application system to (M);
Step b, target application system receive application system and pass the Web Services information of coming, and deciphering search condition (A) is resolved search argument (X), and start-stop row number (N) is to (M);
Step c, target application system generate a random number (Y) with random function, and the target application system is (Y X) deposits in buffer memory MAP or the database as key-value pair;
Steps d, target application system are retrieved according to search condition (X, N is to M), generate result set (S), the target application system (Y) and (S) generation XML format string return to application system;
Step e, application system show (N) to (M) of Query Result, then arrive (M) to target application system transmission (Y) and new start-stop row number (N) if any page turn over operation;
Step f, target application system obtain search argument (X) according to (Y), and amalgamation start-stop row number (N) re-executes query manipulation and returns to application system to (M).
