A method for providing database management system support to a source application configured to operate with a source database management system Is provided. The method comprises detecting database management system communications issued by the source application to the source database management system; and responsive to said database management systems communications, impersonating the source database management system to the source application.

Method and system for transparent interoperability between applications and data management systems

Some embodiments provide a method of emulating a presentation of at least one system object of a first database, based on multiple system objects of a second database. From a client, the method receives a first query for the first database requesting a presentation of the system object. From a metadata storage, the method identifies a second query for the second database that references the system objects of the second database, and generates the requested presentation of the system object. The method replies to the client with the generated presentation.

Emulation of database catalog for migration to a different database

A system for controlling access to a downstream database management system (DMS) is provided. The system comprises an interface to maintain client connections with a plurality of upstream clients; a pooling component to establish a dynamic pool, and to selectively route each client connection to a pool; within each pool maintaining a queue comprising client database requests associated with particular client connections; and selectively granting access to the client database requests within each queue to at least one downstream DMS.

Method and system for workload management for data management systems

For multiple queries written for a first database, some embodiments provide a method of processing the queries on a second database. From a client, the method receives individually each of the multiple queries written for the first database. The method performs an automated process to analyze properties of the second database to determine that the multiple queries can be replaced by a single query to the second database. Based on the determination, the method combines the multiple queries to generate a single query for the second database. The method forwards the generated single query to the second database for execution.

Batching database queries for migration to a different database

Some embodiments provide a method for migrating a set of data objects from a first database of a first database type to a second database of a second database type. The method retrieves a particular set of data from the first database and performs an automated process to analyze the particular set of data in order to select the second database type from multiple other database types. The method presents on a display the selected second database type and a user interface control for migrating the set of data objects stored in the first database to the second database of the second database type. In response to a selection of the user interface control, the method provisions the second database and transfers the set of data objects from the first database to the second database.

One-click database migration with automatic selection of a database

Some embodiments provide an automated method for processing a query. The method receives a query from a client, where the query references an object in a source database, the object having two sets of properties. The method generates a full set of properties by retrieving one set of properties from the target database and retrieving the other set of properties from a metadata storage. Based on the full, combined set of properties, the method generates a new query for execution on the target database.

Static emulation of database queries for migration to a different database

For a query written for a first database, some embodiments provide a method of processing the query on a second database. From a client, the method receives the query written for the first database. The method performs an automated process to analyze properties of the second database to determine that the received query should be replaced by multiple queries to the second database. Based on the determination, the method generates multiple queries for the second database. The method individually forwards each generated query to the second database for execution.

Unbatching database queries for migration to a different database

Some embodiments provide a method for migrating a set of data objects from a first database of a first database type to a second database of a second database type. The method receives a selection of the second database type and receives a selection of a user interface control for initiating the database migration from the first database of the first database type to the second database of the selected second database type. The method provisions the second database and transfers the set of data objects from the first database to the second database.

One-click database migration to a selected database

For an updateable view that is defined for a first database, some embodiments provide an automated method for processing an update to data tuples in a second database, the update specified by reference to the updateable view. The method receives a first query from a client for modifying a particular data tuple presented in the updateable view. From a metadata storage, the method retrieves a definition of the updateable view, where the definition includes a reference to a first set of one or more objects associated with the particular data tuple in the first database. Based on the retrieved definition, the method generates a second query referencing a second set of one or more objects associated with the particular data tuple in the second database. The method executes the generated second query on the second database, to modify the particular data tuple in the second database.

Emulation of database updateable views for migration to a different database

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for dynamic partition selection. One of the methods includes receiving a representation of a query plan generated for a query, wherein the query plan includes a dynamic scan operator that represents a first computing node obtaining tuples of one or more partitions of a table from storage and transferring the tuples to a second computing node that executes a parent operator of the dynamic scan operator. A partition selector operator is generated corresponding to the dynamic scan operator. A location in the query plan is determined for the partition selector operator. A modified query plan is generated having the partition selector operator at the determined location.

Dynamic partition selection

A method for providing interoperability between a plurality of database management system. The method comprises a server communicably connected to a plugin-application; receiving, from the source application, a connection request; intercepting communications issued by the source application to a source database management system; and responsive to said intercepted communications, impersonating the source database management system as a target database management system.
