The document provides an introduction to service-oriented architecture (SOA). It discusses the history and evolution of SOA from earlier approaches like COBOL and SQL. The key components of SOA are services, service consumers, providers, contracts, and registries. Services are reusable components that communicate by exchanging messages. SOA allows for loosely coupled integration of distributed systems and provides benefits like increased return on investment and improved adaptability. Adoption of SOA remains in early stages, with only 19% of organizations having implemented it so far.
Domain is an area of control or sphere of knowledge. number of network points or addresses.
A procedure can take requests is called procedural call, A procedure will response then can use other procedures. DCOM is a proprietary Microsoft technology for communication among software components distributed across networked computers. CORBA is a standard defined by the Object Management Group (OMG) that enables software components written in multiple computer languages and running on multiple computers to work together (i.e., it supports multiple platforms). XML stands for EXtensible Markup Language XML is a markup language much like HTML XML was designed to carry data, not to display data XML tags are not predefined. You must define your own tags XML is designed to be self-descriptive.
In Traditional applications everything is integrated i.e. Radio, cassetplayer, speakers etc. But if we want double cassette, cd player, or digital radio. We have to change the whole thing. Again and again with modular applications, each part is independent. SpeakersS, Amplifier, dbl cassette etc.every combination is possible and easy if the connections are standards.
The service contract informs the service consumer of the acceptable format of a servicerequest, The service contract is stored in a service registry. A service registry is a network-accessible registry that accepts and stores service contracts from providers and makes them discoverable to service consumers.
RPC is Remote Procedure Call. Which set to run automatic on startup. But it don’t sometime. Event logs= eventvwr 1.Information, 2.Warning, 3.Error. Distributed Service is independent share/not.
Oriented mean leaning, tilting, responsiveness. Artifact mean object or piece.
To define the application, data and technical architectures for the system=Blueprint Photographic print of plan or technical drawing etc. A work breakdown structure (WBS) breaks a project into smaller, more manageable components. It is the basis for project planning.
Repository is a store house or warehouse. Business logic is a specific detail & information layer of a particular industry
Autonomy is Independence or self-sufficiency.
CRM is Customer Relationship Mgt.consists of enterprise goals and business strategies. DDA is Digital Differential analyzer. Fast speed and on metrics define.
In a web dev Mashups is a web page or application that uses and combine data, presentation or functionality from 2 or more sources to create new sources. An Application Programming Interface (API) is a particular set of rules and specifications that a software program can follow to access and make use of the services and resources provided by another particular software program that implements that API. It serves as an interface between different software programs and facilitates their interaction, similar to the way the user interface facilitates interaction between humans and computers‘. recurring
Finally, SOA can aid enterprises(compilation, risks, innovation) in improving their reaction times when adapting to changing market conditions.
