Web Services Overview

Screenshot: The transformation in computer system deployment.
Screenshot: The monolithic approach to software development.
Screenshot: Client-server computing separated data management from app logic.
Screenshot: N-tier development created a business-logic layer that accessed data.
Screenshot: Services use open protocols that can be accessed through the Internet.
Screenshot: Structured design involves decomposing larger processes into smaller ones.
Screenshot: Object-oriented development encapsulates both data and behavior into classes and objects.
Screenshot: Component-based development involves a small group of objects with a contractually specified interface, working together to provide an app function.
Screenshot: In service-based development, services are usually components wrapped in a service layer.

Screenshot: A method that returns only account-holder information.
Screenshot: A method that returns both the account-holder's information and address.

Screenshot: A method that returns just the attributes requested.

Component-Based Service Development

Screenshot: Development lifecycle of a component-based service.
Screenshot: The requirements analyst creates a set of artifacts that describes the app.
Screenshot: Degrees of modifiability.
Screenshot: One way to improve integrability is to adapt the service for use over different protocols.
