Further, the interface configuration is acknowledged and recipient, because business is different, development language is different, skill
Heterogeneous applications system caused by art renewal time is different is more and disperses, such as the financial system using java language development, use
.net the crm system (i.e. CRM system) of language development, HR system, OA system or the various updates because of technology
Caused new legacy system, it is therefore desirable to according to different business it needs to be determined that some specific application system is sender or reception
Side, such as financial system send business datum to the crm system as recipient, because crm system is to pass through as sender
Java language exploitation, financial system is that the business datum by .net language development, in the two heterogeneous applications systems is same
Step is that more highly difficult isomeric data is synchronous.
Wherein, the groundwork of interface configuration are as follows: setting sender's interface name, URL, access mode: POST/GET,

Table 2
Further, business datum includes following one or more combinations: being divided by type of service business datum
Multiple business datum groups that class obtains, business datum is carried out multiple tasks group that hash algorithm (Hash) distribution process formed,
Not pretreated business datum.
To multiple business datum groups that business datum is classified by type of service, i.e., according to different service class
Type, such as procurement data, recruitment data, customer data etc., are divided into different business datum groups.
The multiple tasks group that hash algorithm (Hash) distribution process is formed is carried out to business datum, at the distribution of hash algorithm
Reason is carried out in the configuration of field corresponding relationship, in actual operation, i.e., an additional field in the configuration of field corresponding relationship,
Hash algorithm is called, business datum can be divided into multiple tasks group according to hash algorithm.Preferably, when business datum reaches
Certain data volume, such as million grades, hash algorithm (Hash) distribution uses 0-9 this 10 random numbers, i.e. hash algorithm
(Hash) table length is set as 10, that is, business datum is divided into 10 100,000 grades of thread, carries out Multi-task Concurrency, can be same
Shi Jinhang data are synchronous.
Hash algorithm (Hash) is exactly transformed into the input of random length by hashing algorithm the output of regular length,
The output is exactly hashed value.This conversion is a kind of compression mapping, that is, the space of hashed value is generally much less than the sky inputted
Between, different inputs may hash to identical output, be briefly exactly a kind of message compression by random length to certain
The function of the eap-message digest of one regular length.Hash algorithm (Hash) function in practice refers to is mapped to one one on a large scale
A small range, a small-scale purpose is mapped on a large scale often to save space, so that data are easy to save.It is general
Logical hash algorithm (Hash) has two dot characteristics: creation Hash table (hash algorithm (Hash) Map) needs first to specify size, i.e., silent
The Hash table of how many a elements can be stored by recognizing creation one, its default size is 16；When constantly to hash algorithm
(Hash) in Map when addition element, hash algorithm (Hash) Map is more and more fuller, multiplies when the element of addition has reached the loading factor
When long with table, it is necessary to dilatation.When dilatation, the element for having been mapped into some position (bucket) in Hash table originally needs again
Then Hash again copies to original data in new Hash table again.
Because there is mathematical proof, dilatation is at twice of size, so that the element number of Hash is minimum again.For common Hash
For table, the cost of dilatation is very big.Because it is as follows that common hash algorithm (Hash) calculates address mode: hash algorithm
(Hash) (Key) %M, as follows for extreme example in order to demonstrate conveniently:
Assuming that hash function is hash algorithm (Hash) (x)=x, the length of Hash table is 5 (having 5 buckets):
When key=6, the element that hash algorithm (Hash) (6) %5=1, i.e. Key are 6 is stored in first bucket；
When key=7, the element that hash algorithm (Hash) (7) %5=2, i.e. Key are 7 is stored in second bucket；
When Key=13, the element that hash algorithm (Hash) (13) %5=3, i.e. Key are 13 is stored in third bucket
In ...
Assuming that hash algorithm (Hash) table length dilatation now is at 8, then the data that Key is 6,7,13 all need again
Hash.Because
When key=6, the element that hash algorithm (Hash) (6) %8=6, i.e. Key are 6 is stored in the 6th bucket；
When key=7, the element that hash algorithm (Hash) (7) %8=7, i.e. Key are 7 is stored in the 7th bucket；
When Key=13, the element that hash algorithm (Hash) (13) %8=5, i.e. key are 13 is stored in the 5th bucket
In ...
As can be seen from above: after dilatation, the position of element becomes entirely.Such as: the pantogen that Key is 6 is stored in the
In one bucket, need to store into the 6th bucket after dilatation.
Finally, recipient initiates synchronization request, sync server receives the request according to request receiving part, and starting synchronizes
Service, sync server is according to the business datum in recipient's actual business requirement Timing Synchronization server.
The present invention also proposes a kind of data synchronization unit, is applied in sync server, device includes:
Business classification element is classified for the business datum to sender according to type of service, and multiple business are obtained
Data group；Receiving part is requested, for receiving synchronization request from recipient；Data synchronizer unit, including application programming connect
