Furthermore, we define a more general class of graph queries called generalized pattern queries on attributed multigraphs. The goal of this class is to find paths and subgraphs that satisfy query reachability and predicates. The query language is expressive: It allows (i) using regular expression ...
Currently, the Notebook in Graph Studio includes a Java interpreter and a Python interpreter to access the Graph APIs and a PGQL interpreter to execute pattern-matching queries against the graph. In addition, there is a SQL interpreter to access data in relational tables, as well as a SPARQL...

The most commonly used way to add navigation into graph queries is to start with a basic pattern matching language and augment it with navigational primitives based on regular expressions. For example, the friend-of-a-friend relationship in a social network is expressed via the primitive (friend...

For example, a topological query may be better expressed as a regular expression or a context free expression, which are not readily expressed as SQL. An RDBMS that expects only queries that are SQL and/or tabular typically does not have data structures that are dedicated to graph analytics. ...
