Flag field, type are integer, for identifying whether this record can be deleted.
(2) server timing empties interim concordance list SynchronousDB, and creates and empty record sheet, and table name is
The time emptied is inserted into SynchronousDBTime table CreateTime field by SynchronousDBTime.
CreateTime field, for recording the time for emptying SynchronousDB table.When carrying out null clear operation, lead to
Know that the machine client last time of connection empties the time of SynchronousDB table, if client is before this table records the time
Without more new database, then client needs backup database again.
(3) server to the increasing of database, delete, change operation, interim concordance list SynchronousDB is all recorded
In, until specific time needs synchronous local data base and server database, this table of reading service device client database record
The data for needing to modify execute corresponding data manipulation on local data base, to keep local data base and server count
It is consistent according to library data, after data synchronously complete, delete all records of Flag=1 in interim concordance list SynchronousDB.
The operation that server increases database data, deletes, changing is included in interim concordance list SynchronousDB
Method are as follows: database name is included in the DBName field of table, table name is entered into TableName field, which major key institute passed through
The operation done is included in PriKeys field, and the operation increase, delete, changing is included in CRUD field, and the time of single record creation is charged to
CreateTime field is finally completed the record to server-side database change.
(4) after each sync database data of local client, a Txt file is created in the machine, stores the last item
The modification time of record.Per the subsynchronous preceding SynchronousDBTime table of reading first, whether field CreateTime is judged
The time is emptied greater than the machine Txt file record, empties time, explanation if it is greater than the machine Txt file record
SynchronousDB table has null clear operation, needs backup database again；The time is emptied if it is less than the machine Txt record, is said
Bright SynchronousDB table does not empty, then read SynchronousDBTime.CreateTime the machine Txt record the time it
All records of Flag=0 in interim concordance list SynchronousDB afterwards, according to every record corresponding data library name
(DBName), data table name (TableName), major key set (PriKeys), in corresponding this in query service device end record
Hold, then executes that CRUD value is corresponding to be increased, delete, changes operation in local data base.After completing this time synchronized update of all data,
The record change that Flag=1 is done to the server data specifically read, illustrates that this record has been synchronized to local data base.
