The method comprises: step one, establishing a connection with a database dictionary server; step two, querying a database dictionary table, acquiring all storage process objects of a current database user, and constructing a to-be-detected object list; step three, determining whether an undetected object exists in the to-be-detected object list, and if exists, performing code parsing on a storage process of the undetected object to generate a syntax tree and an annotation list, and adding the undetected object to a global symbol tree; step four, according to the syntax tree and annotation list that are generated in step three and the global symbol tree, generating a local symbol stack in an abstract syntax tree traversing process and calling a static detection component, and performing static detection on the storage process of the undetected object, so as to obtain a static detection result; and step five, generating a static detection report according to the static detection result.

The invention provides a display method and device for a recording file of a terminal when fast forward and fast backward are carried out. The method comprises the steps of receiving an instruction for recording a file, traversing each ts (Transport Stream) packet in a ts stream in sequence, and if a current ts packet comprises a picture start identifier and a preset frame type identifier, taking the address of the picture start identifier of the current ts packet as a start address of a key frame; searching each follow-up ts packet in sequence, if a target ts packet comprises the picture start identifier, taking the address of the picture start identifier of the target ts packet as an end address of the key frame, until the start address and end address of each key frame in the ts stream are determined; and if an instruction for performing a fast forward function or a fast backward function is received, analyzing data between the start address and the end address of each key frame in the ts stream, thereby displaying the key frames.

An FPGA-based NVMe SSD PCIe packet analysis method belongs to the field of storage technology. The invention solves the problem that the traditional PCIe data packet parsing process is complex and needs to occupy too many logical resources. The present invention simplifies the data packet parsing process by means of the characteristics of the TLP parameters of the received NVMe data packet and the change rule of the address, and can accurately determine the type and function of the TLP packet without parsing the TLP address; and the FPGA internal The FIFO cache module composed of BlockRam only needs to record the TLP parameters and number fields, and does not need to record the address of the TLP. Compared with the traditional data analysis method, the simplified method proposed by the present invention can save 57% while ensuring the complete function of the data analysis module logical resources. The invention can be applied to the field of storage technology.

The present invention proposes a method for analyzing DICOM files in a file directory, which includes inputting a file directory, comparing its file structure with the file storage structure record, and obtaining the changed part. The file storage structure record saves the accessed file directory The file structure of the file; the change part is merged into the file storage structure record; the analysis result of the change part is merged into the DICOM file storage structure record, and the DICOM file storage structure record saves the DICOM file analysis result of the accessed file directory; from DICOM The file storage structure record obtains the DICOM file storage structure of the input file directory. The present invention saves the file structure of the accessed file directory and the corresponding DICOM file analysis results, so that only the changed part needs to be analyzed during re-access, and the resolution speed during re-access is accelerated.

The invention discloses a pan-root domain name resolution method. The method includes: the pan-root server at least saves the NS records of the root, TLD and secondary domain name servers; There are two types of data, A and B, and differentiated data management rules are implemented; a backup service record is added on the pan-root server to verify the security and reliability level of the domain name to be queried; the pan-root server is divided into main pan-root servers. The root server and the mirror pan-root server implement different mirroring rules. The invention provides the record preservation of the root and N-level subdomain authoritative query through the pan-root server, ensures the record preservation and update of the independent operation of the pan-root, provides localized root mirroring rules, reduces parsing delay, and improves security and performance. degree of stability.

The invention provides a hypermedia edition producing method and system. A three-stage description file structure of a multimedia description file, a hot zone description file and a main-file description file is adopted, the paragraph processing is canceled and the main-file description file is generated directly by the hot zone description file, so the hierarchy and the complexity degree of the description files can be reduced, and thus the workload of analysis when a hypermedia file is played is reduced and the probability of an analysis error is reduced; meanwhile, the multimedia description file is created according to a file type but not a single object and one description file is created for each type of multimedia objects, so the number of independent multimedia description files isgreatly reduced and thus the probability that the description file is lost or is linked wrongly is reduced; and to sum up, the hypermedia file production and analysis process can be obviously simplified, and thus the hypermedia file production efficiency is greatly improved and the probability of the error occurred in analysis is reduced.
