| | Object-oriented programming - Wikipedia, the free encyclopedia |
 | | Objects - packaging data and functionality together into units within a running computer program; objects are the basis of modularity and structure in an object-oriented computer program. | | | The concept of objects and instances in computing had its first major breakthrough with the PDP-1 system at MIT which was probably the earliest example of capability based architecture. | | | In computer science, object-oriented programming, OOP for short, is a computer programming paradigm. |

| | plope - Object Orientation |
| | Object orientation is a software development pattern that is used in many programming languages (C++, Java, Python, Eiffel, Modula-2, others) and computer systems which simulate "real-world" behavior. | | | The core purpose of object orientation is to allow developers to create, to the largest extent possible, a system based on abstractions of the natural language of a computer (bits and bytes) into real-world things (Employees and Forms) that we can understand more quickly and more readily. | | | These objects last from the time that a programmer creates one on behalf of the user via his code until such time that the system (on behalf of the programmer or site administrator) deems it necessary to throw away the object in order to conserve space or indicate an "end" to the user's session. |

| | ALU: Object Orientation |
| | Objects can be defined in terms of functions that encapsulate certain data, and operations on objects can be defined by functions encapsulating the objects. | | | This function object may then be passed as input to other functions, perhaps be composed with other functions, and eventually, applied to inputs to produced a value. | | | The behavior of operations on objects (methods) are themselves defined as first-class objects, which can be specialized by the programmer. |

| | An Introduction to Object Orientation |
| | OO is organized around objects, their interface, how the objects communicate with each other, their state at a given instance, etc. Thinking of analysis and design of software as objects is very important because humans think in terms of objects. | | | Object orientation (OO) has changed the way the software industry approaches software development, in particular, how technologists approach analysis, design, code reuse, and implementation. | | | Object orientation is an approach (not a specific tool) that is organized around objects rather than actions, data, or logic. |

| | Modular Object Orientation Explained |
| | The concept of object orientation was first introduced in 1967 when it was first implemented in a language known as Simula. | | | The more object oriented programs that a user runs, the more object worlds are created on the one machine. | | | Module code is shared in memory, which means that each object that is created exists as a new instance of data, but the code is not reloaded. |

| | Class normalization is a process by which you reorganize the structure of your object schema in such a way as to increase the cohesion of classes while minimizing the coupling between them. | | | My experience is that agile software developers, be they application developers or Agile DBAs, must minimally have an understanding of object orientation if they are to be effective. | | | Another common approach to improving object schemas is refactoring (Fowler 1999), an approach overviewed in Database Refactoring. |

| | Journal of Vision - Incidental vs. deliberate coding of object orientation across eye movements, by Eccelpoel & ... |
| | This could mean that transsaccadic integration subserves object identification and that object orientation, unlike object position, is an integral part of the object representations that are matched to achieve identification. | | | Inspired by this account, we hypothesized that object semantics should modulate the detection of intrassaccadic changes in object orientation, but not in object position. | | | According to Boucart and Humphreys (1997) this is the case because shape is represented in the object lexicon which interfaces object identity and semantics. |

| | Object-Oriented Programming Concepts |
| | An object is a software bundle of related variables and methods. | | | You need to understand what an object is, what a class is, how objects and classes are related, and how objects communicate by using messages. | | | A class is a blueprint or prototype that defines the variables and the methods common to all objects of a certain kind. |

| | Elements of Object Orientation |
| | In both classes and objects, the attributes that apply (data types) and the methods or operations that act on them (functions) are encapsulated into a single software artifact that can only be accessed or effected by means of the methods, which serve as the interface to the objects generated from the class. | | | An object is an instance of a class -- an occurrence, or a 'concrete representative of' or 'example of' a class. | | | An object is an actual item or concept that is found in and relevant to the problem or service addressed by a software system. |

| | A later scan from one angle can be compared to this mapped to determine the orientation of the object regardless of the object's orientation or scale, according to the researchers. | | | The researchers' method calls for scanning objects from every angle using a range finder that maps the peaks and valleys of the object's surfaces. | | | Researchers from the University of Valencia in Spain have improved the process with a method of mapping three-dimensional objects in a way that records every possible point of view of the object. |

| | Object Orientation: Making the Transition by Meilir Page-Jones |
| | Unfortunately, object orientation, though a valuable and sophisticated approach to constructing software, has been over-marketed by unscrupulous vendors. | | | Second, an object, with its identity independent of its state, is also a natural mechanism for implementing distributed software. | | | Thus, many shops are pulled into object orientation because of the kind of modern system that they need to develop and thence because of the tools that support such development. |

| | ICS 121: Object-orientation |
| | An object is an instance of a class, not a class itself. | | | Object-orientation is an approach to analysis, design, and implementation where the system is viewed as a set of communicating objects. | | | In general, if you find yourself writing code that tries to detect the class of some object and uses that information in an if-statement or case-statement, it would be better to use subclasses. |

| | TDAN Dave Hay - OO and IE - Analysis Process |
| | A second problem with the object-oriented approach to data is that it tends to identify object classes simply from the use cases, as the objects seen by the potential system users. | | | Unfortunately, to the extent that it is done, data analysis typically only addresses the objects seen by the users, without trying to understand their inherent structure. | | | First of all, since object-oriented technology does not require normalization, this step is often skipped, precluding development of a sound understanding of the underlying structure of the data involved. |
