31 results about "Comma-Separated Values" patented technology

A comma-separated values (CSV) file is a delimited text file that uses a comma to separate values. A CSV file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The use of the comma as a field separator is the source of the name for this file format.

Iterative definition of flat file data structure by using document instance

InactiveUS20060259519A1Interactively create a parsing schema quicklyMinimal knowledge necessarySemi-structured data mapping/conversionSpecial data processing applicationsXML schemaEnterprise application integration
Flat file formats are used widely in Enterprise Application Integration (EAI) and Business to Business (B2B) solutions. The formats describe the layout of the meaningful information within the data stream in such a way so that the parsing of that stream and extraction of the information can be automated. An example of a flat file format is a Comma Separated Values (CSV) format, where units of data are delimited between each other by using comma character. Another example is a positional format where the units of data occupy certain positions relative to each other within the data stream. The common task that is performed very often is conversion of the documents from various flat file formats into an XML representations and vise versa. The algorithm of iterative definition of the flat file structure from document instance described herein simplifies the process of defining the conversion rules for the flat file formats. These rules are used by components that perform conversion from flat file format to XML and back. The algorithm allows definition of those rules by working with the flat file document instance and iteratively creating an XML schema from that instance.

Logic test method and device suitable for reactor protection system

The invention relates to a logic test method and device suitable for a reactor protection system. The logic test method comprises a construction step, a call step, an operation step and a judgment step, wherein the construction step is as follows: constructing test programs and a truth table based on a comma separated values (CSV) format, wherein the truth table comprises the logic diagram index information of the reactor protection system, an input variable, an output variable, the voluation information of the input variable, the input variable of the output variable, and an execution time; the call step is as follows: reading the logic diagram index information, calling the test programs corresponding to the logic diagram index information; the operation step is as follows: reading the input variable and carrying out voluation on the input variable in accordance with the voluation information of the input variable, and carrying out logic operation in accordance with the called test program and the execution time so as to obtain the output value of the output variable; and the judgment step is as follows: judging whether the output value of the output variable is consistent with the expected value, if yes, outputting correct result information, and if no, outputting wrong result information. In the logic test method, the test is carried out by constructing the truth table based on the CSV format and the test program, thus being convenient for modification and regulation, and avoiding human errors.

Packing method based on line storage database engine

The invention discloses a packing method based on a line storage database engine, which comprises a line storage database, and following operations are carried out based on the line database: creating a compress table, specifying a corresponding compressing level, and importing data files with CSV (Comma Separated Value) format into the created compress table. The method is characterized in that: the compress table is a common data table showed externally for supporting general DML / DDL (Data Manipulation Language / Data Definition Language) operation; the compress table comprises a master HOT data segment and a slave LOB large object segment realized internally, wherein the master HOT segment is used for storing internally defined attribute lines, and the slave LOB segment is used for storing a compression method control structure and compressed data content; the compress table is used for supporting various query languages, and when in query, even though all fields in the line need to be read into memory, the related line data only needs to be decompressed and queried; the compress table is used for supporting update operation, and only decompressing updated lines when in update; and the compress table is used for supporting speedy deletion, only delete mark is made, and when no record is in a slave line, a master line is automatically deleted; and the compress table is deleted. According to the invention, through a line storage database technology, without changing a storage engine physical result, the technology of compression and storage according to line is realized, and the effect of high compression ratio of the line storage database is achieved.

Method for converting CSV (Comma-Separated Values) data labeled by metadata to RDF (Resource Description Framework) data

The invention discloses a method for converting CSV (Comma-Separated Values) data labeled by metadata to RDF (Resource Description Framework) data. The method comprises the following steps: reading and analyzing a CSV file, obtaining tabular data, and storing the tabular data into a memory data structure; reading and analyzing a metadata description file, obtaining metadata, and storing the metadata into the memory data structure; combining with the obtained tabular data and metadata, generating an RDF triple set, and storing the RDF triple set into the memory data structure; and outputting the generated RDF triple set as an RDF data file of a Turtle grammatical format. The method for converting the data format converts the CSV data labeled by a metadata model vocabulary defined by a W3C (World Wide Web Consortium) technical specification <Web Tubular Data and Metadata Model> into the semantically equivalent RDF data, so that a traditional software tool can be utilized to conveniently publish the RDF data obtained by conversion onto an associated data network for various semantic web applications to share, reuse and process the tubular data from the CSV file, and therefore, a great quantity of large-coverage CSV data can perform the maximum potential.

A http retrieval method for csv fragments identified by uri

The invention discloses an HTTP (Hyper Text Transport Protocol) retrieval method for a CSV (Comma-Separated Values) fragment marked by a URI (Uniform Resource Identifier). The HTTP retrieval method comprises the following steps that: a client resolves a fragment URI and obtains a main resource URI and a CSV fragment identifier; the client sends the selection mode and the selection range of the CSV fragment to a server; the server extracts the CSV fragment according to the selection mode and the selection range of the CSV fragment; the server returns the extracted CSV fragment to the client; and the client obtains the CSV fragment and displays or stores the CSV fragment. The HTTP retrieval method for the CSV fragment marked by the URI disclosed by the invention has the advantages that on one hand, the expansion on a current HTTP / 1.1 protocol is not needed; and on the other hand, the RFC 7111 international standard 'URI Fragment Identifiers for the Text / CSV Media Type' is supported, and compared with a conventional technical scheme of extracting the fragment after the client downloads a complete CSV file, the method provided by the invention has the advantages that the network bandwidth can be greatly reduced, and the communication time delay is reduced.
