Abstract: Disclosed are systems and methods for implementing contract-based polymorphic and parallelizable user-defined scalar and aggregate functions. The systems and methods can include receiving a query including a plurality of user-defined functions, parsing the query into a plurality of nodes (e.g., basic operation unit or atomic operator), generating an execution plan that minimizes data transfer between the plurality of nodes, and executing the plan in a distributed environment. Each of the plurality of user-defined functions can correspond to one of a plurality of nodes.

Abstract: In one embodiment, a computer system comprises one or more processors, and a memory module communicatively connected to the one or more processors. The memory module comprises logic instructions stored on a computer readable medium which, when executed on the one or more processors configure the one or more processors to receive, in a hybrid caching module, database query, determine whether at least a portion of an existing execution plan stored in a memory module coupled to the hybrid caching module can be reused to implement the database query, reuse at least a portion of an existing execution plan stored in the memory module coupled to the hybrid caching module when possible, and generate a new execution plan when the memory module lacks an existing execution plan adaptable for use with the database query.

Abstract: Systems and methods to indicate whether to store a database query language module in a local directory or a global directory are disclosed. An application program can be created once, tested once, and deployed in separate environments. The database query language modules can be shared among a group of application programs running in a common environment. Separate query language modules can be maintained for each environment.
