Gauthier and Dave Truxal wrote a white paper called "IBM SanFrancisco
Application Development Environment." The following is an extract from
that white paper:
SanFrancisco is more than a set of business processes, business com-
ponents, or business frameworks. It is designed for future evolution
and growth, with an architecture that enables reuse within SanFran-
cisco itself. SanFrancisco has three architected layers: application
segment~specific "Core Business Processes (CBPs)," multiple ap-
plication segment "Common Business Objects (CBOs)," and an
application-independent distributed object-oriented infrastructure
called the "Foundation."
CBPs are application specific and, typically, high-level commercial
business process frameworks, such as General Ledger, Warehouse,
and Order Management.
CBOs support multiple application segments, and are primarily
commercial objects or miniframework "patterns." Examples of
CBOs are customer name and address and currency.
The Foundation layer supports all application segments in all indus-
tries. It includes an application infrastructure comprised of a set of
fundamental object building blocks, which are typically collaborating
objects and services. Examples of Foundation content include: entity,
dependent, and command objects; a set of utilities that provides ses-
sion management, synchronization, and conflict control; and a set of
query, transaction, and event/notification services.
Let's focus now on some of the claims made for SanFrancisco and con-
sider the implications for CRM.
A closer look at Web services
The interrelationship between business processes, business objects, and a
foundation infrastructure was future defining in more senses than one. The
concept of processes, objects, and "glue" interworking to create applications
has now been extended into the Internet world. What SanFrancisco and
WebSphere made possible in terms of corporate applications has given rise to
the concept ofWeb services~with the addition of the Internet in the recipe.
SanFrancisco was the first high-profile commercialization of the concept
of objects and methodology coming together to create applications. There-
