  • Multi-parameter data type frameworks for database environments and database systems
    Patent number: 12339858
    Abstract: A multi-parameter data type framework can, among other things, provide a more comprehensive, systematic, and/or formal mechanisms for determining an appropriate data type for a data set. For example, the multi-parameter data type framework can be used to allow analytic tools to virtually automatically figure out an appropriate data type for a set of data values.

  • Discovering candidate referential integrities in a database
    Patent number: 12141124
    Abstract: A database system enumerates one-column candidate referential integrities (1CRIs) from a plurality of input columns in one or more relations. The database system applies one or more disqualification tests to the 1CRIs to eliminate illegitimate 1CRIs resulting in a list of non-disqualified 1CRIs, wherein the disqualification tests are applied to an 1CRI being tested (hereinafter (A*,B*), A* representing a set of values of a referenced column or columns and B* representing a set of values of a referencing column or columns) until (A*,B*) is disqualified or until all of the disqualification tests have been executed and (A*,B*) has not been disqualified, in which case (A*,B*) is added to the list of non-disqualified 1CRIs, wherein each of the disqualification tests reduces the likelihood of incorrectly adding (A*,B*) to the list of non-disqualified 1CRIs.

  • PROCESSING OF DELIMITER-SEPARATED VALUE (DSV) DATA
    Publication number: 20240220726
    Abstract: In some examples, a system receives delimiter separated value (DSV) data, and categorizes a character in the DSV data into a selected layer of a plurality of layers, where characters in a first layer of the plurality of layers comprise data characters, characters in a second layer of the plurality of layers comprise delimiters, and characters in a third layer of the plurality of layers comprise grouping symbols to group a string of characters into a semantic unit. The system parses the DSV data according to the categorizing.
