Abstract: Disclosed herein are an apparatus and method for managing threads to perform the divided execution of software. The apparatus includes a server-side thread management apparatus and a client-side thread management apparatus. The server-side thread management apparatus includes a server execution unit, a server device management unit, and a server connection management unit. The server execution unit executes software to be executed in a divided manner, and generates and manages one or more threads for processing one or more of graphics and sound processing functions of the executed software. The server device management unit extracts one or more of a function related to a graphics task and a function related to a sound task from the software. The server connection management unit sends the one or more functions, extracted by the server device management unit, to a client-side thread management apparatus via the threads generated by the server execution unit.

Abstract: The following description relates to a query optimization method in distributed query engine and an apparatus thereof. A query optimization method according to an exemplary embodiment includes establishing a query plan based on query; classifying data to be included in result data of a high level operation from result data of a low level operation as a first data to be used for intermediate operations existing between the low level operation and the high level operation and a second data not to be used for the intermediate operations, based on the query plan; and modifying the query plan for the second data not to be an input value for the intermediate operations
