Abstract: A method for performing text searches on graph data stored in a database is provided. The method may include receiving, from a client, a request to perform a text search to locate a target string in the graph data stored in the database. The request may be in accordance with a declarative graph query configured to query the graph data stored in the database. The response to the request may include performing the text search to locate, in the graph data stored in the database, one or more records of strings that are exact matches, approximate matches, and/or linguistic matches for the target string. Related systems and articles of manufacture, including computer program products, are also provided.

Abstract: A method for ad hoc graph data processing may include receiving, from a client device, a graph processing algorithm defined as a part of an anonymous block. The anonymous block may be a data manipulation language (DML) statement containing the graph processing algorithm. The anonymous block may be compiled. The graph progressing algorithm included in the anonymous block may be executed on at least a portion of a graph data stored in a database. The anonymous block being compiled and executed without generating a database object corresponding to the anonymous block at the database. Related systems and computer program products are also provided.

Abstract: Various embodiments for a triple integration and querying system are described herein. An embodiment operates by identifying a plurality of triples corresponding to a knowledge graph, and generating a table in a database into which to import the set of triples. The table includes a subject column, a predicate column, and multiple object columns across different datatypes. Values from the triples of the knowledge graph are loaded into the table and a query is executed on the table.

Abstract: Various embodiments for a triple integration and querying system with dictionary compression are described herein. An embodiment operates by identifying a table of a database with four or more columns with triple formatted data including one subject column, one predicate column, and two or more object columns. It is determined that a master dictionary is to be generated for the both the subject column and the predicate column based on an identical datatype being used for both columns. A subject data dictionary and a predicate data dictionary are generated. A unique value is assigned a same unique identifier a in both the object data dictionary and the subject data dictionary. A master dictionary including both the unique values from the subject data dictionary and the predicate data dictionary is generated. Values in the subject column and the predicate column are replaced based on the unique values from the master dictionary.
