What is Specification in Business? Definition

A good specification should be clear and concise, so that there is no ambiguity about what is being requested. A well-written specification can help to ensure that a project is completed on time and within budget. Specification in business refers to a document that spells out the specific requirements for a product, service, system or component. The purpose of a specification is to ensure that what is delivered meets the needs of the customer or user.

A Component Context should therefore be regarded as a capability and not shared with other components or bundles. SCR must attempt to satisfy the component configuration created by newInstance before activating it. If SCR is unable to satisfy the component configuration given the component properties and the Dictionary argument to newInstance, https://globalcloudteam.com/glossary/component-specification/ the newInstance method must throw a ComponentException. The component factory, however, does not use any of the target services and does not bind to them. The factoryProperties annotation element of Component can be used to provide the same information. This element consists of an array of strings where each string defines an entry.

Why Is a Software Requirement Specification Important?

Otherwise, SCR must log an error message with the Log Service, if present, and the field must not be modified. Care must be taken by the component implementation regarding the field. SCR has no way to know if the component implementation itself may alter the field value. The component implementation should not alter the field value and allow SCR to manage it. SCR must treat the field as if the component implementation does not alter the field value so SCR may retain its own copy of the value set in the field.

Skyscanner is a metasearch platform that lets travelers look for flights at the best rates from Skyscanner’s database of prices. Also, Skyscanner provides its affiliate partners with a RESTful API supporting both XML and JSON as the data exchange formats. In order to improve security, they encourage partners to only use HTTPS protocol to make requests. Vulkan is a cross-platform API that works on the operating system level. It enables developers to create high-quality, real-time graphics in applications and drives the communication between an application and a graphical processing unit.

What is a Specification?

This minimizes the amount of code a programmer has to write; it also allows service components to be loaded only when they are needed. As a result, bundles need not provide a BundleActivator class to collaborate with others through the service registry. An application function describes the internal behavior of a component needed to realize one or more application services. In analogy with the business layer, a separate “application flow” concept is conceivable as the counterpart of a business process.

Tuple – An unmodifiable Map.Entry whose key is an unmodifiable Map containing the service properties of the bound service, as above, and whose value is the bound service object. A component configuration when the component is enabled and the component configuration is satisfied and a component configuration is needed. During the life time of a component configuration, SCR can notify the component of changes in its bound references. A data object can be seen as a representation of a business object, as a counterpart of the representation concept in the business layer.

Examples of Component Specifications in a sentence

ComponentServiceObjects – Allows multiple service objects for a service to be obtained. SCR does all publishing, finding and binding of services on behalf of the component using the Bundle Context of the component’s bundle. This means that normal stack-based permission checks will check SCR and not the component’s bundle. SCR must register the ServiceComponentRuntime service with the service.changecount service property. See org.osgi.framework.Constants.SERVICE_CHANGECOUNT in OSGi Core Release 7. Whenever the Service Component Runtime DTOs available from the ServiceComponentRuntime service change, SCR modify the service.changecount service property with an updated change count value.

If an empty array is specified, the property is not added to the component description. The enabled state of a component description is initially set by the enabled attribute of the component description. The declared component description or null if the specified bundle is not active or does not declare a component description with the specified name.

5.11 Activate Method

It shows an association between interfaces and entities from the logical data model . It does not show information or state that the components manage through the interfaces. Special support is added for references to Loggers from the Log Service specification. SCR will convert a reference to a LoggerFactory to a Logger object on behalf of the component. Delayed Component is updated to clarify when a component configuration may be reclaimed.

SCR must allow other orderings since arbitrary orderings of these elements do not affect the meaning of the component description. Only the relative ordering of property, properties and referenceelements have meaning for overriding previously set property values. DisableComponent – If the specified Component Description DTO represents a valid component description from an active bundle processed by SCR, the component is disabled. This method must return after changing the enabled state of the specified component. Any actions that result from this, such as activating or deactivating a component configuration, must occur asynchronously to this method call.

6 Component Properties

In the following examples, a component requires the Logger Factory service. More specific details can also be put to give a better https://globalcloudteam.com/ understanding about the job. Here is a sample job specification, which is prepared for a marketing manager in a telecom company.

• Agile project management platform — offers functionality for developers to capture details about requirements, use cases or user stories to incorporate into the designs of their products.
• It will come in handy later while brainstorming and monitoring functions.
• The service provided to the component must be type compatible with this class.
• It removes uncertainty about how the design works and improves communication efficiency.
• If a bundle does not have the necessary permission for a multi-location Configuration, then SCR must act as if the Configuration does not exist for the bundle.
• Functional requirements documents are often available as document templates.
• Component properties whose names start with full stop are available to the component instance but are not available as service properties of the registered service.

The name of the bind method or field is used for the name of the reference. The Component Annotations are not inherited, they can only be used on a given class, annotations on its super class hierarchy or interfaces are not taken into account. SCR must obtain the Configuration objects from the Configuration Admin service using the Bundle Context of the bundle containing the component. SCR must only use Configurationobjects for which the bundle containing the component has visibility. A configuration PID to a Configuration object, SCR must use the Configuration object with the best matching PID for the component’s bundle.

Configuring Product Specification

This can sometimes be a challenge, as the customer may not have a good understanding of what is possible or what it will take to meet their needs. In other cases, the customer may have very specific and unrealistic demands. Assumptions are the team’s assumptions about the product and its capabilities that will be correct in 99% of situations.
