CAL (Configurator Abstraction Layer)

What is CAL?

• Configurator Abstraction Layer (CAL)
• Independence from Layers / Configurators
• Framework for building configuration based
  applications
• Extended API
• Set of tools

Entities of a Configurator like IPC during runtime

Forming CAL out of classification of entities
Core functionality
Extended functionality Some configurators might
not provide this functionality by default

Architecture of CAL

IPC based Web App Standard with CAL
Webapp is bundled with the thin Configurator
independent CAL Layer
IPC Stubs are bundled into the webapp
IPC dependent libs are loaded at runtime. No need
for bundling them with the web app

Saving time costs during development

• CAL directly connects
• to the SPC or maybe
• even the SCE layer
• Improved performance
• No unmonitored model change during developm.
• No unexpected IPC Server downtime (e.g.
  someone applies / tests new user exits)
• Independence from network access to the CRM /
  R/3 system.

Upgrading to a new IPC version

Component Development - Idea

• Develop one component, use it everywhere!
• Use additional functionality, which does not come
  with the configurator by default.
• Add interaction between a J2EE component and the
  configuration.

Component Development Online Configuration
A CAL interface is available directly on the
webapp level.

Pricing
CAL can also be used on the SPC layer.

only
CAL can also be used on the SCE Layer if no
pricing is required.

CAL J2EE
See configuration as a service which the J2EE
Session bean provides.Plug in your application,
register forevents or even use a CAL interface
on topof the J2EE Layer which gives you
theadvantage of an Enterprise Architecturefor
all of your CAL enabled applications.
