COM+ Component as a Service
Component Identity
• COM
• Query IUnknown from any of the interfaces of a COM object will returns the same address
• Developers opt-in to consuming, exposing, and defining public-facing service faç ade. • Services and consumers are independently versioned, deployed, operated, and secured.
• COM+
• The component has an attribute that defines its identity • “Components” are no longer tied to their binary object
• They can be unloaded from memory • There can be more than one object representing the same component in memory

Service Orientation
Boundaries are Explicit Services are autonomous
Share schema & contract, not class
Compatibility based on policy
• Data never includes behavior; • Objects with data and behavior are a local phenomenon. • Capabilities and requirements represented by a unique public name; Used to establish service suitability.
COM+
• Usability, Scalability, Maintainability, Availability, Security • Make COM easy & powerful:
• Add “Serviced” Environment • Use Context & Interception

• Decoupling is investment (Coupling is easy RAD) • Loose Coupling:
• Reduce the assumptions that two entities make about each other when they try to exchange information • As the level of assumptions made between two entities goes up so does the efficiency between the two entities New technologies make decoupling easier and • However, at the same time, the two entities are cheaper less tolerant to changes

COM+ is based on COM
COM Is:
• Component software model:
• Component def. “…binary, self-contained, reusable, language neutral piece of software”
Interface-based Dynamic Loading Runtime Metadata
Service-Oriented

Message-based Schema+Contract Binding via Policy
Session Objectives and Agenda
• Component oriented programming
Misc
• Miscellaneous files (VBScript Client)
• C++ ATL based COM+ • C#, WPF based client • C#, EneterpriseService based COM+ • C#, Host for the IMax Service

The Demo Solution
• COM is a Microsoft solution based on:
l
The OO paradigm
l
l
Binary reuse
Interfaces

More Characteristics:

l l
Clients bind to objects at runtime
Integrated services, easy-to-use tools, available applications Market for reusable, off-the-shelf, client and server components
I Have to tell you about the future and the past!
From Objects to Services
Object-Oriented

Polymorphism Encapsulation Subclassing
Component-Based
