Object Persistence
An object database or object-oriented database is a database management system in which information is represented in the form of objects as used in object-oriented programming. Object databases are different from relational databases which are table-oriented. A third type, object–relational databases, is a hybrid of both approaches. Object databases have been considered since the early 1980s. Overview Object-oriented database management systems (OODBMSs) also called ODBMS (Object Database Management System) combine database capabilities with object-oriented programming language capabilities. OODBMSs allow object-oriented programmers to develop the product, store them as objects, and replicate or modify existing objects to make new objects within the OODBMS. Because the database is integrated with the programming language, the programmer can maintain consistency within one environment, in that both the OODBMS and the programming language will use the same model of representat ...

Object-Oriented Model
Object-oriented programming (OOP) is a programming paradigm based on the concept of " objects", which can contain data and code. The data is in the form of fields (often known as attributes or ''properties''), and the code is in the form of procedures (often known as '' methods''). A common feature of objects is that procedures (or methods) are attached to them and can access and modify the object's data fields. In this brand of OOP, there is usually a special name such as or used to refer to the current object. In OOP, computer programs are designed by making them out of objects that interact with one another. OOP languages are diverse, but the most popular ones are class-based, meaning that objects are instances of classes, which also determine their types. Many of the most widely used programming languages (such as C++, Java, Python, etc.) are multi-paradigm and they support object-oriented programming to a greater or lesser degree, typically in combination with i ...

Objective-C
Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. Originally developed by Brad Cox and Tom Love in the early 1980s, it was selected by NeXT for its NeXTSTEP operating system. Due to Apple macOS’s direct lineage from NeXTSTEP, Objective-C was the standard programming language used, supported, and promoted by Apple for developing macOS and iOS applications (via their respective APIs, Cocoa and Cocoa Touch) until the introduction of the Swift programming language in 2014. Objective-C programs developed for non-Apple operating systems or that are not dependent on Apple's APIs may also be compiled for any platform supported by GNU GCC or LLVM/Clang. Objective-C source code 'messaging/implementation' program files usually have filename extensions, while Objective-C 'header/interface' files have extensions, the same as C header files. Objective-C++ files are denoted with a file extension. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
InterSystems Caché
InterSystems Caché ( ) is a commercial operational database management system from InterSystems, used to develop software applications for healthcare management, banking and financial services, government, and other sectors. Customer software can use the database with object and SQL code. Caché also allows developers to directly manipulate its underlying data structures: hierarchical arrays known as M technology. Description Internally, Caché stores data in multidimensional arrays capable of carrying hierarchically structured data. These are the same “global” data structures used by the MUMPS programming language, which influenced the design of Caché, and are similar to those used by MultiValue (also known as PICK) systems. In most applications, however, object and/or SQL access methods are used. Caché ObjectScript, Caché Basic or T-SQL can be used to develop application business logic. External interfaces include native object binding for C++, Java, EJB, Activ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ObjectStore
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 to Relational Mapping overhead required when using object-oriented data with a Relational Database. It is inspired by the 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 swi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
