Abstract
The App Economy is being defined in thousands of enterprises as we speak, but certainly has key
requirements that include: • Multi-channel access—systems that are open to Web apps, mobile
apps, internal systems and partner systems • Enforced data integrity and security—we can no
longer enforce business logic in our UI controllers; it has to be centrally enforced • Integration—
the details of how systems are created and deployed should have no bearing on multi-channel
access, but they need to integrate multiple internal databases and interact with partner systems
• Business agility— if the App Economy means our systems define how we do business, then we
must be able to create (and alter) these systems as near as possible to real-time speed •
Simplicity—there are only so many rocket scientists; you should be able to compete in the App
Economy with software that leverages the strengths of as many people in your organization as
possible, including non-developers This talk will provide a specific example of how APIs can
respond to these challenges, including take-home code.

APIs are a Challenge. Logic Is Worse.
Large Projects, Code-Intensive: Slow, Complex, Uneven Quality
Backend is Nearly Half, plus
Substantial Back Office UI.
Big Numbers:
20 pages, per table (1-2 months)

Logic
Client Logic
• Read/Write
• Display
• Mobile App Services
API Logic - Automated
• Nested Document Model
• Mapping and Transformation Logic
• Pagination, Optimistic Locking
• Generated Key Handling
• Extensible – tags, JavaScript
• Shared Server Logic Invocation
Reactive Logic
• Multi-Table Derivations and Validations
• Row/Column Security
• Extensible – JavaScript, Libraries
• Automatic Object Model
Integration Logic
• Webhook Creation
• Webhook Processing
• SalesForce, SAP, …

1. In-Coming Requests
Resources: Abstraction Layer
• Point/click Mapping and Transformation
• Nested Document Model
• Schema Hiding, for API Consumers
Activates Underlying Logic
• Separate Concerns: API vs. Backend Logic

2. Reactive Logic
40X More Concise
Conventional: ~500 Lines of Code
Live API Creator: 13 Rules

3. Out-going Requests – Systems Integration
Automatic Object Model
Discovery – Code Completion
Resources – point/click mapping
and transformation
Extensibility – Loadable Libraries

3. Database Integration
Different Servers
Different Server Types
Optimized Cross-DB Joins

Reactive Logic
Enable Instant Business Relationships
APIs Share Logic. Automatically.

…Not Agile
Thin APIs are incomplete
without the critical logic and
integration.
And that’s where most of the
work lies – not agile.
