Indexed cache is stored in web front-end.
Such as, a target data record of background server back to web front-end is index " 7 " and value " 200 ", needs to turn
Change corresponding resource apparatus type into.
Index " 7 " is corresponded to by field name from the Hash Map for indexing field name according to web front-end caching first
“object_class”。
Similar field（“object_class”）Shared about more than 100, these field names largely have resource dictionary,
The resource dictionary is stored in the storage of system-level resource, by system maintenance, the corresponding resource dictionary quantity of each field name
Nearly all it is more than tens, and the ID of resource dictionary is that value " 200 " is repeated between field name, but the money of certain field name
Source dictionary ID is that value is unique.
So finding field name " object_class " by indexing " 7 ", the range for reducing lookup value improves lookup effect
Rate avoids being possible to debugging.
Then, the resource dictionary range limited by field name " object_class ", finds the corresponding money of value " 200 "
Source device type " base station controller（BSC, Base Station Controller）”.
" 7 " will be indexed and resource apparatus type " BSC " is used as the resource data, be loaded into web indexed caches.
It should be noted that some field names are generic field names, without corresponding resource dictionary, as String field,
Time field, amount field etc..The value of these fields does not need to search corresponding resource apparatus type, directly by the number of targets
It is loaded into web indexed caches as the resource data according to the index in record and value.
The web indexed caches are user interfaces（UI, User Interface）Available data.
Step（3）：Web front-end keeps long connection with background server, and newly-increased target data is obtained from background server
Record, makees step by the target data record（2）In resource supplement conversion after be added in the web indexed caches,
