 2 Forces of the number of the three figures in the power of the device shown in Figure 1

4 force this number The indication of the inquiry. Hugh way

 The following description is combined with the description.

 1, the instructions of the query device in this book, this, Web system B / S (ow e / Seve, customer / each) mode, the customer must be installed, only need to refer to each side of the

 The number in the source, centralized control. The same, can be multi-user geographically the same query, the square user query operation, improve the system availability

 The query device is arbitrarily inquired, and special, both for the customer and for each, and may be neither the customer nor the end, the devices 11 and 12 are stored together 13 and displayed 14, wherein

 Number 11, after receiving the query, the number of queries that need to be queried (ie, the query to be queried), the number of the plurality of sources meets the remainder.

 2, the number of required data in the storage system has been counted, and the number of storage systems is different.

 B B2. B, each and every CP CP2. CP

 11 1, 2. "B B2, . B" respectively satisfies the remainder, and + +2. + Respectively CP CP2. The remainder of the CP is satisfied.

 12, in the number of 11 to the number of special format.

The same storage 13 is used to divide the number of 12 into the same end. Show 14, in the same period of the cycle, the number will be displayed to the customer.

 To better understand and describe the technical solution of the present invention, the following is a description of the technical solution of the query device or/and the query process in the context and the process, and the process is shown in the third step.

 3, Liben 1 shown in the query device query source number process flow, in the integration process, the following steps, step 301, the query device receives the number of customers query. The user can provide the query interface provided by the customer.

 The query starts with the same query, and the query is generated by the customer's query. The query contains the information about the query and the query mode information, and sends the query to the query device. Among them, the query mode information needs the number of queries or / and the information of the sum, and the number of each and each information to be queried. Information can

 Query the number of queries required.

 Step 302: Querying the number received in the number 11 to determine whether it is necessary to query the number of the sums, and if yes, executing step 303. Otherwise, executing step 305

 Step 303, 304, 11 query to determine each of the various queries, and the function is used to query each number

 , a unique file is generated by the number of each of the remaining numbers and the number of each.

 In step 303, the number of steps of the work needs to be queried, 吋 . Each message and system

In the middle of each Query message messages, received each, returned, parsed, parsed generated unique files. The query user of the above query message generates the query, adds public control information, message flow, and (more than the same, or can be 0 255, ten can only be determined), receive and so on.

 Steps 305, 11 query whether the remainder is, if yes, execute step 306. Otherwise, perform step 3 0.

 Step, query whether the remainder, the rest of the query received before the rest of the query query comparison, if the same, then the query is not otherwise, the query is residing. The non-query operations (row sorting, paging, etc.) that the user needs to go to, do not need to query the remainder. Therefore, in the case that the query is not exhausted, the query can be queried, and 11 is needed directly in the same, but no more than 11 , while improving efficiency, with resources.

 Steps 306, 11 Query The query needs to be queried, and the remaining ones are satisfied by the respective ones.

 Preferably, the rabbit needs to establish a connection for each query, and P (e a oce g ., central processor) is the same resource, this

 , in the line of integration, connection and system, allocate a certain amount of connection resources in memory, in the system

 Connect to improve performance.

The step will be the need to unify the connected fixed force query Of ,

 Inches . Storage, by the storage user's query

 Satisfied with the rest. Store the query in the storage mode to determine which of the distributions that need to be queried are re-determined to satisfy the remainder. In , the maximum amount of inquiry (more than 1000) can be required. Therefore, it is only necessary to use the technology of the present invention. Therefore, the technique is more flexible.

 Step 307: Generate a unique file to be stored. Better, better stored, to

Integrity, this, the storage will be satisfied to the rest of the storage to the only

 Generate a unique file.

 Steps 308 and 12 convert the special files in the generated unique file into a unified format, and store the format special in the same end of each end.

 Step 309, showing 14 or the same period in the cycle, will be displayed to the customer.

 Step 310, customer or cycle in the same.

 Preferably, it is better to monitor whether all of the completions have been completed to successfully complete the inquiry. Step 303 of the above process, step 306, can be performed in the same manner as in each process.

 , the result of the work , the middle , the phase ,

, you can query. Preferably, the prevention of the same or more of the same due to other special reasons, and the second query is the same as the pre-determined, the same paragraph in the process (the same as the same), the near is not, then

 Query, the query will be queried, and the user will query the next time. Preferably, the user submits the same query in the same query (the same as 2, that is, within the 2 that needs to be queried), to improve the efficiency of the query, and reduce the query, which will share the same force, more than 2 months. The force component 2 is the same as 4,

 11 are inquiries

 , which is the same as the first one, and the second is the same.

 Ben, the integration process The following steps

 Step 1, and analyze the configuration information, information, and information required by the system.

 Step 2, the information obtained by the unified analysis, more, 吋, each of the full of more than enough.

 More steps, and

 The way in the previous process in the process, no longer here. Step 3. The information obtained by the unified analysis is more

 , each, each

Satisfied with the rest.

 More steps, and

The manner in each of the foregoing processes is not repeated here. Step 4: The special format obtained in the steps 2 and 3 is replaced by a format, and the format is stored in the same middle of each end.

 Step 5: In the same customer, the displayed will be displayed on the customer interface.

 Steps 3 and 4 in the above process are not required. You can either perform step 3 or step 4 first.

 The Ming technology can be used in many ways, and the user can query the physical use of the technology, and the general query (that is, the different queries can be different in the source), and overcome the existing wood-based query can only query the source. In the middle

 ) and the query is inefficient, therefore, the query has been improved with the technology of the present invention.

In terms of query efficiency, the special source in different sources is changed into a unified format, the customer displays the provider, and the format is stored in the middle of the same end, and is displayed by the customer or the middle of the cycle, and now in the query Or the part of the cycle will be displayed to the customer, without waiting for the query to be displayed again, and the user's speed is improved, the user experience is improved, the secondary query, if the user needs to query the non-query operation, directly In the same way, the query operation is not required, and the efficiency of the non-query operation is improved.

 However, the wood in this field can be both spiritual and solid. If the repair of this book is in this

 The requirements and their equivalents to the wood also include and .
