8. a kind of method for reading data, which is characterized in that based on data reading system described in claim 6 or 7, comprising:
Reading client receives the data read command that user provides, and determines what user need to read according to the data read command
Data；
The reading client judges whether the data that need to be read include binary data, if so, reading two to described
Binary data server sends the first data read request, and the reading binary data server receives the reading client
The first data read request sent searches the corresponding binary data of the first data read request, by the binary system
Data return to the reading client, and the reading client receives the readings binary data server described in receive
The binary data returned after first data read request；
The reading client judges whether the data that need to be read include non-binary data, if so, to the reading
Database server sends the second data read request, and the reading database server receives what the reading client was sent
Second data read request searches the corresponding non-binary data of the second data read request, by the nonbinary number
According to the reading client is returned, the reading client receives the reading database server and is receiving second data
The non-binary data returned after read requests.
9. method for reading data according to claim 8, which is characterized in that
The lookup corresponding binary data of the first data read request includes:
The reading binary data server determines the corresponding first write time point of the binary data；
The binary data is searched in the corresponding file of the first write time point；
It is described to search the corresponding non-binary data of the second data read request and include:
The reading database server determines the corresponding second write time point of the non-binary data；
