Be introduced the method for writing data that the embodiment of the present invention provides below, method for writing data described below is based on above-described data writing systems.
The process flow diagram of the method for writing data that Fig. 3 provides for the embodiment of the present invention, with reference to Fig. 3, this method for writing data can comprise:
Step S100: write client receives the data write instruction that user provides, determines according to described data write instruction the data that user need write;
When needs write data, user provides data write instruction by human-computer interaction interface etc. to write client, accordingly, the data write instruction that reception user provides by write client, after the data write instruction that client can provide reception user, determine according to these data write instruction the data that user need write.
Step S110: said write client judges whether the described data that need write comprise binary data;
Step S120: if so, then described binary data is sent to write binary data server by said write client, and said write binary data server receives the binary data that said write client sends, and stores described binary data;
The data that need write can only include binary data, can only include non-binary data, not only can also comprise binary data but also comprise non-binary data.When only including binary data in the data that need write, maybe when not only having comprised binary data but also comprised non-binary data in the data that need write, write client will judge that these data that need write comprise binary data.
If write client judges that the data that need write comprise binary data, then the binary data that these data that need write comprise is sent to write binary data server, received the binary data of this write client transmission by this write binary data server after, this binary data is stored.
Optionally, write binary data server is after the binary data receiving the transmission of write client, can first the binary data of this reception be added in a queue, then carry out the mode stored according to the data of each team's head obtained in this queue, all binary data that write client sends are stored in order.
Step S130: said write client judges whether the described data that need write comprise non-binary data;
Step S140: if so, then described non-binary data is sent to write into Databasce server by said write client, said write database server receives the non-binary data that said write client sends, and stores described non-binary data.
When only including non-binary data in the data that need write, maybe when not only having comprised binary data but also comprised non-binary data in the data that need write, write client will judge that these data that need write comprise non-binary data.
If write client judges that the data that need write comprise non-binary data, then the non-binary data that these data that need write comprise is sent to write into Databasce server, received the non-binary data of this write client transmission by this write into Databasce server after, this non-binary data is stored.
Optionally, write into Databasce server is after the non-binary data receiving the transmission of write client, also can first the non-binary data of this reception be added in a queue, then carry out the mode stored according to the data of each team's head obtained in this queue, all non-binary data that write client sends are stored in order.
That is, if only include binary data in the data that need write, then write client and store only these data that need write being sent to write binary data server; If only include non-binary data in the data that need write, then writing client will only can send to write into Databasce server to store these data that need write; If not only comprise binary data but also comprise non-binary data in the data that need write, then write client this need to be write data and both sent to write binary data server to store, database server is sent to again to store, concrete, write client will send to write binary data server to store by the binary data that comprises of these data that need write, and the non-binary data in the data that need write this sends to write into Databasce server to store.
Optionally, Fig. 4 shows the method flow diagram stored binary data in the method for writing data that the embodiment of the present invention provides, and with reference to Fig. 4, this can comprise the method that binary data stores:
Step S200: said write binary data server determines the first write time point receiving described binary data;
For avoiding storing excess file in a catalogue, therefore, write binary data server to be stored in receiving binary data respectively in different files according to time of reception.
Such as, if 2 points of 3 seconds 456 milliseconds of binary data receiving write client and send when 8 days 1 August in 2015, then can set up file " 2O150808 ", the binary data storage received on August 8th, 1 is in this " 2O15O808 " file, in like manner, also can set up file " 2O1508 " and store the binary data received all in August, 2015, or set up the binary data received when " 2O15080801 " stores all 2015 on August 8,1.
Optionally, the concrete division of write binary data server in-list, can decide according to the number of the binary data of this write binary data server reception every day, to avoid the overabundance of data or how many stored in certain file.
If write binary data server according to the time point receiving binary data by the binary data storage of this reception in different files, then this write binary data server can after the binary data receiving the transmission of write client, determine the time point receiving this binary data, obtain the first write time point.
Optionally, write binary data server is after the binary data receiving the transmission of write client, also can determine further and store geographical location information and the classification information of this binary data, so that when reading data to this write binary data server, improve data read rates and precision.
Step S210: judge whether that there is described first write time puts corresponding file;
Step S220: if so, then described binary data storage to described first write time is put in corresponding file;
If the first write time put corresponding file and is created, then direct the binary data storage of reception to be put in corresponding file to this first write time.
Step S230: if not, then creating described first write time puts corresponding file, is put in corresponding file described binary data storage to described first write time.
If the first write time put corresponding file and is not created, then needing first to create this first write time puts corresponding file, and then this binary data storage is put in corresponding file to this first write time.
Optionally, when writing the binary data stored in binary data server and exceeding the memory capacity of this write binary data server, the binary data stored in this write binary data server can be deleted according to the priority of time, the binary number data of oldest stored are deleted at first.
Optionally, Fig. 5 shows the method flow diagram stored non-binary data in the method for writing data that the embodiment of the present invention provides, and with reference to Fig. 5, this can comprise the method that binary data stores:
Step S300: the second write time point receiving described non-binary data determined by said write database server;
Same, for avoiding in write into Databasce server storing excess file in a catalogue, write into Databasce server also can be stored in receiving non-binary data in different files according to time of reception respectively.
Optionally, the concrete division of write into Databasce server in-list, can decide according to the number of the non-binary data of this write into Databasce server reception every day, to avoid the overabundance of data or how many stored in certain file.
If the non-binary data of this reception is stored in different files according to the time point receiving non-binary data by write into Databasce server, then this write into Databasce server can after the non-binary data receiving the transmission of write client, determine the time point receiving this non-binary data, obtain the second write time point.
Optionally, write into Databasce server is after the non-binary data receiving the transmission of write client, also can determine further and store geographical location information and the classification information of this non-binary data, so that when reading data to this write into Databasce server, improve data read rates and precision.
Step S310: judge whether that there is described second write time puts corresponding file;
Step S320: if so, then described non-binary data being stored to described second write time puts in corresponding file;
If the second write time put corresponding file and is created, then the direct non-binary data by reception is stored to this second write time and puts in corresponding file.
