Understanding Service Component Architecture

Service-component architecture is a collection of rules, terms and conditions proposed for the development of applications base on service-oriented architecture (SOA), which defines how computing entities work together to carry out work for each other. SCA make simpler the designing and integration of business applications that are built using an SOA by making separate the business logic from its implementation so that the programmer can focus on assembling an integrated application without bothering about particulars of its implementation. SCA is based on the concept that all the tasks in an enterprise should exist in the outline of services that are joined into composite to address specific business necessities.

SCA brings together different  technologies, programming languages, frameworks and platforms for  Web service components and for the techniques used to connect them. SCA can be broken down into four major divisions or models.

• The assembly model, This defines how components are brought together, connected and packaged as services autonomous of the programming language.
• The implementation model, This defines how services are packaged and accessed for specific programming languages.
• The policy model, this defines service policies autonomous of the programming code.
• The bindings model, this defines how components are contacted  independent of the programming code.

When properly executed, SCA can assist an organization to reduce the workload on its developers, shorten learning curves, make possible reuse of services and update policies without having to alter the programming. SCA also aid control over access methods and the implementation of security-related countermeasures.
