Problems solved by technology

[0031] This method of generating unique identifiers is inconvenient for distributed architectures
Address-based generation cannot be implemented in every backend without increasing system complexity while maintaining constraints on identifiers (short size with limited number of characters, high performance, compatibility, etc.)

Embodiment Construction

[0111] figure 1 A general context for implementation of various embodiments is illustrated.

[0112] A database system 100 is provided for storing objects that can be placed and retrieved by a number of external devices. The database system can be implemented as a relational database or an object-relational database management system (ORDBMS). For example, an ORDBMS can be as developed by Oracle Corporation TM tagging system.

[0113] For example, database system 100 may store PNRs created by travel agent computer-implemented management systems.

[0114] The database comprises a memory unit 101 for storing objects, such as PNRs, and their associations with unique identifiers. For example, a unique identifier may be a record locator.

[0115] According to various embodiments, the memory unit 101 only stores objects that are active throughout the system. In the case of a PNR, memory unit 101 will only have an active PNR in memory. Thus, a PNR is removed from memory unit ...

Abstract

A system for associating a unique identifier with an object wherein, the system comprising : - a database (100) with a memory unit (101), an index unit (102) and a control pointer unit (103), - at least one identifier management unit (120, 121, 122), and - at least one update unit (140), wherein : - there is a finite set of identifiers organized in pages, each page comprising a bitmap representing the availability of the identifiers, - said pointers to data in the index comprise a pointer to a last page loaded by an identifier management unit, and a pointer to a last page updated by an update unit.

Description

[0001] Invention name [0002] Management of unique identifiers in the database technical field [0003] The present invention relates to the management of databases that can be accessed on a large scale by a large number of clients with a high update rate. [0004] More specifically, the present invention relates to the assignment of identifiers to objects stored in a database, the identifiers associated with a given object being unique within the database at any given time. Background technique [0005] In large-scale information systems, objects stored in a database are usually assigned an identifier comprising, for example, an alphanumeric character string. [0006] Identifiers can be used as a means for identifying a given object with a data structure of limited size. By manipulating the identifier instead of the object itself, overall system resources are optimized. [0007] Objects processed and stored in a database may not be static in nature. Objects can be cre...
