Naked Objects
Naked objects is an architectural pattern used in software engineering. It is defined by three principles: The naked object pattern's innovative feature arises by combining the and principles into a principle: The naked objects pattern was first described formally in Richard Pawson's PhD thesis which includes investigation of antecedents and inspirations for the pattern including, for example, the Morphic user interface. The first complete open source framework to have implemented the pattern was named Naked Objects. In 2021, Pawson announced that he had subsequently applied the same pattern to the Functional Programming programming paradigm, as an alternative to the object-oriented programming paradigm, creating a variant of the Naked Objects framework called Naked Functions. Benefits Pawson's thesis claims four benefits for the pattern: #A faster development cycle, because there are fewer layers to develop. In a more conventional design, the developer must define and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Architectural Pattern (computer Science)
An architectural pattern is a general, reusable solution to a commonly occurring problem in software architecture within a given context. The architectural patterns address various issues in software engineering, such as computer hardware performance limitations, high availability and minimization of a business risk. Some architectural patterns have been implemented within software frameworks. The use of the word "pattern" in the software industry was influenced by similar concepts as expressed in traditional architecture, such as Christopher Alexander's ''A Pattern Language'' (1977) which discussed the practice in terms of establishing a pattern lexicon, prompting the practitioners of computer science to contemplate their own design lexicon. Usage of this metaphor within the software engineering profession became commonplace after the publication of ''Design Patterns'' (1994) by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides—now commonly known as the "Gang of F ...

Object Database
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 represent ...

Direct Manipulation Interface
In computer science, human–computer interaction, and interaction design, direct manipulation is an approach to interfaces which involves continuous representation of objects of interest together with rapid, reversible, and incremental actions and feedback. As opposed to other interaction styles, for example, the command language, the intention of direct manipulation is to allow a user to manipulate objects presented to them, using actions that correspond at least loosely to manipulation of physical objects. An example of direct manipulation is resizing a graphical shape, such as a rectangle, by dragging its corners or edges with a mouse. Having real-world metaphors for objects and actions can make it easier for a user to learn and use an interface (some might say that the interface is more natural or intuitive), and rapid, incremental feedback allows a user to make fewer errors and complete tasks in less time, because they can see the results of an action before completing the ...

Restful Objects
Restful Objects is a standard covering RESTful interfaces to domain object models. The specification is published under a Creative Commons license. Representations and resources defined by the standard The standard defines a small set of JSON representations covering the generic constructs in a domain object model including the following: * A list of links to domain objects * A single domain object * A property, collection, belonging to a domain object * An action that may be invoked on a domain object * An action result (which will typically include a domain object or list) * A domain service (essentially a stateless domain object) * A small number of very specific representations such as Home, Version, and User. Restful Objects also defines a standard set of resources for accessing or manipulating these representations. The specification defines which HTTP methods may be used with each resource, and their meaning. The table below shows a partial summary: Taken together the ...

Model-driven Architecture
Model Driven Architecture (MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. Model Driven Architecture is a kind of domain engineering, and supports model-driven engineering of software systems. It was launched by the Object Management Group (OMG) in 2001."OMG pursues new strategic direction to build on success of past efforts" Overview Model Driven Architecture® (MDA®) "provides an approach for deriving value from models and architecture in support of the full life cycle of physical, organizational and I.T. systems".

Domain-driven Design
Domain-driven design (DDD) is a major software design approach, focusing on modeling software to match a domain according to input from that domain's experts. Under domain-driven design, the structure and language of software code (class names, class methods, class variables) should match the business domain. For example, if software processes loan applications, it might have classes like loan application, customer, and methods such as accept offer and withdraw. Domain-driven design is predicated on the following goals: * placing the project's primary focus on the core domain and domain logic; * basing complex designs on a model of the domain; * initiating a creative collaboration between technical and domain experts to iteratively refine a conceptual model that addresses particular domain problems. Criticisms of domain-driven design argue that developers must typically implement a great deal of isolation and encapsulation to maintain the model as a pure and helpful constru ...

Agile Software Development
In software development, agile (sometimes written Agile) practices include requirements discovery and solutions improvement through the collaborative effort of self-organizing and cross-functional teams with their customer(s)/ end user(s), adaptive planning, evolutionary development, early delivery, continual improvement, and flexible responses to changes in requirements, capacity, and understanding of the problems to be solved. Popularized in the 2001 ''Manifesto for Agile Software Development'', these values and principles were derived from and underpin a broad range of software development frameworks, including Scrum and Kanban. While there is much anecdotal evidence that adopting agile practices and values improves the effectiveness of software professionals, teams and organizations, the empirical evidence is mixed and hard to find. History Iterative and incremental software development methods can be traced back as early as 1957, Gerald M. Weinberg, as quoted in " ...

Data Access Layer
A data access layer (DAL) in computer software is a layer of a computer program which provides simplified access to data stored in persistent storage of some kind, such as an entity-relational database. This acronym is prevalently used in Microsoft environments. For example, the DAL might return a reference to an object (in terms of object-oriented programming) complete with its attributes instead of a row of fields from a database table. This allows the client (or user) modules to be created with a higher level of abstraction. This kind of model could be implemented by creating a class of data access methods that directly reference a corresponding set of database stored procedures. Another implementation could potentially retrieve or write records to or from a file system. The DAL hides this complexity of the underlying data store from the external world. For example, instead of using commands such as ''insert'', ''delete'', and ''update'' to access a specific table in a databas ...
