Abstract: A method of configuring a virtual database performed by a computing device is disclosed. The method may include: generating a plurality of schemas by mapping a meta table space including meta information for a schema to the schema; and generating a plurality of virtual databases based on at least one schema among the plurality of generated schemas. Herein, one of the plurality of schemas is mapped with one meta table space.

Abstract: A method for managing a virtual database example includes acquiring a first query related to a first object of a first virtual database, issuing an ownership of the first object through a first master front end node corresponding to the first virtual database, and altering first meta information of the first object according to the first query, through a first process which acquires the ownership of the first object. The method also includes requesting an invalidation of a first data dictionary cache about the first meta information of the first object through the first master front end node, receiving a first completion signal indicating that the invalidation of the first data dictionary cache is completed, performing first commit for an alteration of the first meta information of the first object, and collecting the issued ownership of the first object.

Abstract: Disclosed are methods for updating data for multiple users in a database management system performed by a computing device, comprising: determining whether there is an already modified target row during a modification task for at least one target row; generating at least one reselected target row by reselecting a modification target in the at least one target row when there is the already modified target row; determining whether there is an already modified reselected target row during a modification task for the at least one reselected target row; and omitting the modification task for the at least one reselected target row, performing the modification task for the at least one reselected target row, or performing a rollback for the modification task for the at least one reselected target row according to the type of instruction statement included in the modification query when there is the already modified reselected target row.

Abstract: Disclosed is a method for remotely managing a database performed by a gateway server including at least one processor. The method for remotely managing the database may include: receiving an access information registration request for using a second database server from a first database server; generating access information including first information for a first object usable by the first database server based on the access information registration request, the first object being positioned in the second database server; and transmitting a virtual object corresponding to the first object to the first database server based on the access information.

Abstract: Disclosed is a method for processing a query related to a plurality of partitions included in a plurality of tables having different partition information, which is performed by a computing device including one or more processors. The method includes acquiring the plurality of partitions for processing the query. The method includes acquiring global partition indexes for encompassing the acquired partitions and acquiring local partition indexes corresponding to the acquired partitions, respectively. The method includes processing the query at least partially based on the global partition indexes and the local partition indexes.
