A visual language for querying and updating graphs
The response will be the collection of all subgraphs of the database that have the desired pattern. Abstract QGRAPH is a new visual language for querying and updating graph databases.

That is, it is now possible to merge your current graph data (node or edge tables) with new data using the MATCH predicates to specify graph relationships in a single statement, instead of separate INSERT/UPDATE/DELETE statements.
To learn more about how match can be used in merge DML refer to MERGE Statement The SHORTEST_PATH function finds shortest path between any 2 nodes in a graph or starting from a given node to all the other nodes in the graph.
With the help of edge constraints users can restrict the type of nodes a given edge is allowed to connect.
This gives users a better control over their graph schema.Abstract QGRAPH is a new visual language for querying and updating graph databases.In QGRAPH the user can draw a query consisting of some vertices and edges with specified relations between their attributes.Since, nodes and edges are stored as tables, all the operations that are supported on relational tables are supported on node or edge table.
Here is an example: Graph extensions are fully integrated in SQL Server engine.
Since delivering Visual Basic 8.0 in VS 2005, the VB team has been working on the next generation language extensions and enhancements – Visual Basic 9.0.
