Latest Patents

One of Mahbub Hasan's latest patents is titled "Dynamically learning optimal cost profiles for heterogeneous workloads." This invention involves a relational database management system (RDBMS) that accepts a workload comprised of one or more queries against a relational database. The RDBMS evolves a default cost profile into multiple cost profiles using fixed or dynamic evolution. Each cost profile captures various cost parameters for the workload and is represented by a multi-dimensional matrix. The RDBMS dynamically determines the optimal cost profile for the workload by mapping the cost profiles to the workload using a random walk scoring algorithm or a biased walk scoring algorithm. This process helps in selecting and performing one or more query execution plans based on the optimal cost profile.

Another significant patent is "Enabling cross-platform query optimization via expressive markup language." In this invention, a database system receives a user request that invokes a data set function (DSF) and utilizes a property provided by the DSF. The system determines the availability of a function descriptor for the DSF, expressed as markup language instructions. This descriptor defines the property of the DSF, allowing the database system to effectively define a property for the DSF.
