'''ObjectStore''' is a commercial [[object database]], a specialized type of [[NoSQL]] [[database]] designed to handle data created by applications that use [[object-oriented programming]] techniques, avoiding the [[object–relational mapping]] overhead required when using object-oriented data with a [[relational database]].  It is inspired by the [[Statice (software)|Statice]] database originally developed at [[Symbolics]].

ObjectStore is innovative in its use of the [[C++]] language to make database access transparent.  Objects can be created in a database by overloading the operator new().  In this way, one can create new [[C++]] objects directly in the database yet these persistent objects look and behave just like normal [[C++]] objects.  Data is mapped into memory as operating system pages. When data is referenced in a different page, by making use of signals, ObjectStore traps the pointer exception and transparently brings objects in from the database by bringing in the required page(s). In addition, by use of a technique called [[Pointer swizzling|swizzling]], the database can be accessed from different platforms, with pages being 'swizzled' as they are brought into memory on page faults to correct [[big endian]] versus little endian platform issues as well as [[virtual function table]] layout. The design of ObjectStore is described in a 1991 paper<ref name="objectstore-cacm-1991">{{citation

ObjectStore was originally created in 1988 by [[Object Design, Incorporated]], which was based in [[Burlington, Massachusetts]] and founded by several former Symbolics employees, including [[Daniel Weinreb]]. In 2002 the product was acquired by [[Progress Software]], which continued to develop the technology, expanding its use beyond the object database market to target uses as a database for [[real-time computing]], specifically designed for [[RFID]] data management, and as a [[database caching|cache]] for relational databases.

In 2013, Progress Software sold off many of its non-core products to Aurea Software, Inc., a newly formed operating subsidiary of ESW Capital, the investment arm of Trilogy Enterprises. As part of the deal the ObjectStore product line moved to a separate operating subsidiary of ESW Capital.

The ObjectStore product is used in many fields, including [[telecommunications]], financial services, travel, GIS, and the government.

One of the early successful applications of the product was with [[Telstra]] to handle 13 and 1300 numbers in Australia - similar to 1800 numbers in the US.  The product enabled the real time mapping of those numbers to a number closest to the caller - for example a local taxi company or the nearest open [[Pizza Hut]].<ref name="allBusiness">{{citation
