Large object processing system and large object processing method thereof

A large object processing system, comprising:

• a storage device, storing a plurality of large object variable forms, a process variable (PV) processing module, and a large object processing module, wherein the PV processing module comprises a data analyzing unit and a PV storage unit, wherein the large object processing module comprises a data router, an object storage calculator, and an object storage;
• a processor, coupled to the storage device, executing the PV processing module and the large object processing module;
• a configurator;
• wherein the PV processing module receives a request for processing and obtains a PV form and a plurality of object values in the PV form according to the request for processing;
• wherein the large object processing module determines whether the plurality of object values comprise object-referencing character strings;
• wherein in response to the plurality of object values that comprise the object-referencing character strings, the large object processing module obtains large object data, which is corresponding to the object-referencing character strings, according to the object-referencing character strings;
• wherein the PV processing module replaces the object-referencing character strings in the PV form with the large object data and organizes the PV form;
• wherein the data analyzing unit receives a request for storing, which corresponds to the PV form;
• wherein in accordance with the request for storing, a large object threshold reader of the configurator reads a corresponding large object threshold comparison table from the storage device;
• wherein the data analyzing unit obtains variable values in succession from the PV form in correspondence to the request for storing;
• wherein the object storage calculator calculates a storage space required by the variable values;
• wherein the data analyzing unit determines whether the required storage space is dedicated to the large object data in accordance with the large object threshold comparison table;
• in response to the storage space required by the variable values being dedicated to the large object data, the data router matching to one of the large object variable forms in accordance with variable names to which the variable values correspond;
• wherein the object storage stores the variable values and outputs the corresponding object-referencing character strings to the PV storage unit;
• and
• wherein the PV storage unit replaces the corresponding variable values in the PV form with the object-referencing character strings.
