Latest Patents

Among his latest patents, two stand out due to their technical complexity and practical applications:

1. **Efficient Compilation of Bounded Recursive Graph Queries on Top of SQL Based Relational Engine**

This patent introduces techniques that enable graph pattern matching queries within a relational database management system (RDBMS) supporting SQL execution. By compiling a graph pattern matching query that includes a bounded recursive pattern into a SQL query, the techniques allow for seamless execution without necessitating any modifications to the existing SQL engine. This innovation significantly improves the capability to execute complex graph queries in a relational context.

2. **Heterogeneous XML Document Support in a Sharded Database**

This invention responds to the need for advanced query handling in sharded database management systems (DBMS). When a coordinator receives a query containing an XML operator referencing a column in a sharded table, it issues a remote query with a new operator to return a TBX BLOB data type. By extracting and reassembling XML images from these objects, the coordinator ensures clients receive the expected results, further pushing the boundaries of data manipulation in sharded environments.
