Component Specifications Definition

If you are using the component inline in an operation or a dag or if you are using the python client to create a component, this field is not required and is set by default. At the present time, much of the information and regulations concerning food and food products remain in a form which makes it difficult to apply automated information processing, storage and transmission methods and techniques. The coverage of food and drug standards by ISO is currently less fruitful and not yet put forward as an urgent agenda due to the tight restrictions of regional or national constitution. The Component Specification details the responsibilities and key characteristics for individual components.

Master data management is a process that creates a uniform set of data on customers, products, suppliers and other business entities from different IT systems. Web Components is a suite of different technologies allowing you to create reusable custom elements — with their functionality encapsulated away from the rest of your code — and utilize them in your web apps. For instance, when two applications share Unicode data, but use different normal forms or use them incorrectly, in an incompatible way or without sharing a minimum set of interoperability specification, errors and data loss can result. For example, Mac OS X has many components that prefer or require only decomposed characters (thus decomposed-only Unicode encoded with UTF-8 is also known as “UTF8-MAC”).

The total finished design output consists of the device, its packaging and labeling, and the device master record. Component means any raw material, substance, piece, part, software, firmware, labeling, or assembly which is intended to be included as part of the finished, packaged, and labeled device. It is also recommended that you do not add operations to a Specification Type. The Component Specification Model Diagram provides a view of the objects within a Specification subject area.

definition of component specification

Web services specifications are often under the umbrella of a quality management system. In systems development, an architectural specification is the set of documentation that describes the structure, behavior, and more views of that system. A formal specification is a mathematical description of software or hardware that may be used to develop an implementation. It describes what the system should do, not how the system should do it. Given such a specification, it is possible to use formal verification techniques to demonstrate that a candidate system design is correct with respect to that specification. This has the advantage that incorrect candidate system designs can be revised before a major investment has been made in actually implementing the design.

The placeholder is replaced by the (auto-generated) local file path where the system has put the argument data passed for the “Input name” input. In general, components are not aware of who they are communicating with. Comments about the glossary’s presentation and functionality should be sent to This site requires JavaScript to be enabled for complete site functionality. Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

An application interaction can also specify the externally visible behavior needed to realize an application service. The details of the interaction between the application components involved in an application interaction can be expressed during the detailed application design using, for example, a UML interaction diagram. An application function describes the internal behavior of a component needed to realize one or more application services. In analogy with the Business Layer, an application processmodels an ordering of application behavior, as a counterpart of a business process. Note that the internal behavior of a component should in most cases not be modeled in too much detail in an architectural description, because for the description of this behavior we may soon be confronted with detailed design issues. An application component may be assigned to one or more application functions.

Component Specification

It provides a simple and functional API for creating custom elements. An application process describes the internal behavior performed by an application component that is required to realize a set of services. For a consumer the services are relevant and the required behavior is merely a black box, hence the designation “internal”. An application collaboration specifies which components cooperate to perform some task. The collaborative behavior, including, for example, the communication pattern of these components, is modeled by an application interaction. An application collaboration typically models a logical or temporary collaboration of application components, and does not exist as a separate entity in the enterprise.

An application interface can be assigned to application services, which means that the interface exposes these services to the environment. An application interface specifies how the functionality of a component can be accessed by other elements. An application interface exposes application services to the environment. The same application service may be exposed through different interfaces, and the same interface may expose multiple services. Also in the application architecture, the inter-relationships of components are an essential ingredient.


An application event may have a time attribute that denotes the moment or moments at which the event happens. For example, this can be used to model time schedules; e.g., an event that triggers a daily batch process. An application event is an application behavior element that denotes a state change. An application function represents automated behavior that can be performed by an application component.

  • Component validation involves developing a set of test cases for a component and developing a test harness to run component tests.
  • The placeholder is replaced by a local file path where the component program is supposed to write the output data.
  • There are different types of technical or engineering specifications , and the term is used differently in different technical contexts.
  • CBSE for reuse is concerned with developing components or services that will be reused in other applications.
  • Components serve as a container for various reusable definitions – schemas , parameters, responses, examples, and others.

This element is used in the same way as data objects in well-known data modeling approaches, most notably the “class” concept in UML class diagrams. A data object can be seen as a representation of a business object, as a counterpart of the representation element in the Business Layer. An application service exposes the functionality of components to their environment. This functionality is accessed through one or more application interfaces. An application service is realized by one or more application functions that are performed by the component.

The HBRC has published more than 15 books which cover building activities like earthworks, plastering, etc. This type of specification is a collaborative effort between a specwriter and a quantity surveyor. This approach is unusual in North America, where each bidder performs a quantity survey on the basis of both drawings and specifications. In many countries on the European continent, content that might be described as “specifications” in the United States are covered under the building code or municipal code. Civil and infrastructure work in the United States often includes a quantity breakdown of the work to be performed as well.

A component that manages account transactions may define an on-line transactions interface that implements this business rule. Main DescriptionThis artifact specifies the details of a component identified in the Component Model. The specification shows the interfaces offered definition of component specification and used by the component, identifies where business rules are placed, and details the operations and their signatures for each interface. Adaptor components address the problem of component incompatibility by reconciling the interfaces of the components that are composed.


An application interaction represents a unit of collective application behavior performed by two or more application components. An application collaboration represents an aggregate of two or more application components that work together to perform collective application behavior. The application component element is used to model entire applications (i.e., deployed and operational IT systems, as defined by the TOGAF framework ) and individual parts of such applications, at all relevant levels of detail. In software development, a functional specification (also, functional spec or specs or functional specifications document ) is the set of documentation that describes the behavior of a computer program or larger software system.

A data sheet describes the technical characteristics of an item or product, often published by a manufacturer to help people choose or use the products. A data sheet is not a technical specification in the sense of informing how to produce. A requirement specification is a documented requirement, or set of documented requirements, to be satisfied by a given material, design, product, service, etc. It is a common early part of engineering design and product development processes in many fields.

Specifications are a type of technical standard that may be developed by any of various kinds of organizations, in both the public and private sectors. It is common for one organization to refer to the standards of another. Voluntary standards may become mandatory if adopted by a government or business contract.

It can be informal, in which case it can be considered as a user manual from a developer point of view, or formal, in which case it has a definite meaning defined in mathematical or programmatic terms. In practice, many successful specifications are written to understand and fine-tune applications that were already well-developed, although safety-critical software systems are often carefully specified prior to application development. Specifications are most important for external interfaces that must remain stable. Behavior in the Application Layer is described in a way that is very similar to Business Layer behavior. Also here, a distinction is made between the external behavior of application components in terms of application services, and the internal behavior of these components; i.e., application functions that realize these services.

Web Components

The development cost of reusable components may be higher than the cost of specific equivalents. This extra reusability enhancement cost should be an organization rather than a project cost. Generic https://globalcloudteam.com/ components may be less space-efficient and may have longer execution times than their specific equivalents. An application service represents an explicitly defined exposed application behavior.

The Element.attachShadow() method attaches a shadow DOM tree to the specified element. Universal product code means the product identifier used to identify an item sold at retail in the United States. Verification means confirmation by examination and provision of objective evidence that specified requirements have been fulfilled. Quality means the totality of features and characteristics that bear on the ability of a device to satisfy fitness-for-use, including safety and performance. Design output means the results of a design effort at each design phase and at the end of the total design effort. The finished design output is the basis for the device master record.

Functional specification

The documentation typically describes various inputs that can be provided to the software system and how the system responds to those inputs. UK project specification types fall into two main categories prescriptive and performance. Prescriptive specifications define the requirements using generic or proprietary descriptions of what is required, whereas performance specifications focus on the outcomes rather than the characteristics of the components. A specification often refers to a set of documented requirements to be satisfied by a material, design, product, or service.

Externally Defined Components

In one specific instance, the combination of OS X errors handling composed characters, and the samba file- and printer-sharing software , has led to confusing and data-destroying interoperability problems. Data systems that can process, store and transfer information about food and food products need formal specifications for the representations of data about food and food products in order to operate effectively and efficiently. While there is a tendency to believe that “specifications overrule drawings” in the event of discrepancies between the text document and the drawings, the actual intent must be made explicit in the contract between the Owner and the Contractor. The standard AIA and EJCDC states that the drawings and specifications are complementary, together providing the information required for a complete facility. Many public agencies, such as the Naval Facilities Command state that the specifications overrule the drawings. This is based on the idea that words are easier for a jury to interpret than drawings in case of a dispute.

British Dictionary definitions for specification

It defines the methods that can be called by a user of the component. “Requires” interfaceDefines the services that specifies what services must be made available for the component to execute as specified. This does not compromise the independence or deployability of a component because the ‘requires’ interface does not define how these services should be provided. This allows one component to identify to one or more other components that an event has occurred so that the component can respond to it.

An application service should be meaningful from the point of view of the environment; it should provide a unit of behavior that is, in itself, useful to its users. This means, for example, that if this environment includes business processes, application services should have business relevance. An application event may trigger or be triggered by an application function, process, or interaction.

A software component specification should be detailed, focusing on what the software is to do rather than how this is to be done. The traditional use of natural language for this purpose is being superseded by use of more formal notations. Operations – Fully specified Component Specifications assign operations and operation signatures to the interfaces and may define pre- and post-conditions on the operations. Pre- and post-conditions specify the effect of an operation without prescribing an algorithm or implementation. A post-condition specifies the effect of the operation on the components data or state.
