Problems solved by technology

Duplicate storage of this data is futile, especially if the replica is not used for backup or redundancy
Also, all static data must be recreated each time an additional environment is needed (eg, to support additional vendors)

Embodiment Construction

[0019] figure 1 is a block diagram of a software architecture according to some implementations. The architecture includes a provider database instance 100 and reader database instances 110 , 120 , 130 and 140 . In some implementations, reader database instances 110 , 120 , 130 , and 140 can directly access provider database instance 100 data. According to some embodiments, the data can be accessed when the database management system (DBMS) 101 of the provider database instance 100 is not running.

[0020] Typically, a database instance includes at least one operating system processor, physical data storage units, and a piece of main memory (eg, random access memory). These components are in figure 1 The database instance is represented by the database management system, data area and I / O buffer respectively. This specification will use the terms "database" and "database instance" interchangeably.

[0021] Each of the illustrated DBMSs can encompass any known or becoming ...

Abstract

A system may include reading a provider database mapping of file identifiers to page numbers of the provider database, determining one or more shared database objects of the provider database based on the provider database mapping, and registering the one or more shared.database objects in a local namespace of a reader database.

Description

technical field [0001] Some implementations relate to accessing data objects stored within a database system. More specifically, some embodiments relate to sharing database objects of a provider database among one or more reader databases. Background technique [0002] A traditional database-driven system may include several computing environments, each of which is composed of one or more applications and a database instance that stores data associated with the one or more applications. Such a system can provide online transaction processing for several different vendors. For example, each computing environment may store data specific to a particular vendor, and may be responsible for processing on-line transactions on behalf of that vendor. [0003] Typically, systems as described above store large amounts of identical data across each database instance. This data may contain static data not related to any particular vendor, such as payment processing data, shipment data...
