- 3. Reference Implementation Logic 5-10 Pages / Table Jersey REST Server Rich Objects Any device, Anywhere! Jackson REST Listener . JSON Handler Resource / Object Mapping S e c u r i t y I n t e g r i t y Events / Methods Persistence Framework SQL Database Domain Objects JPA (3 Pages / Table)
- 4. The Problem – Today’s Reality Sure… a few weeks… We need a simple mobile app... spec is only 1 page Umm.. I was thinking a few hours
- 5. The Next Generation Proven Technology 1. Rest API: Forms 2. Row/Column Security: Filters 3. Business logic: Events, Reactive
- 6. Why Customers Love Espresso Logic Over 90% time savings Speed of reactive programming with the power of JavaScript Reduced maintenance Use with any front-end Reduced documentation Deploy in Cloud or on premise
- 7. Use Case – Read Only Access to Data RESTful Espresso Servers Espresso Server Access Control Services
- 8. Use Case – Mobile and Web Applications RESTful Espresso Espresso Server Server(s) Access Control Business Logic
- 9. Use Case – Complex Enterprise Applications RESTful Espresso Servers Databases Access Control Espresso Server Business Logic B2B integration SOA Services External External Backends Backends
- 10. Data Model Customer name, balance, credit_limit Orders amount_total, paid Product price LineItem qty_ordered, product_price, amount
- 11. Time to Market, plus… Issue Espresso Documentation The executable cocktail napkin Maintenance Automatic ordering – eliminates the archaeology of maintenance Quality Automatic reuse – logic applied to every use case Performance Automatic optimization – automatics enterprise design patterns
- 12. Manufacturing and Capacity Planning Application Application manages and plans and optimizes factory operations for a Fortune 1000 company Inputs • Orders • Machines – Run rate – Setup time • ABC code – Product priority – Customer priority Processing Used to be 9 people full time using Excel Now takes 20 to 30 minutes per day Outputs • Raw materials orders • Factory plan
- 13. Demo Slides
- 14. Build a RESTful API 1. Register your database URL 2. Select Tables (joins automated) 3. Optional Alias / Project
- 15. Security: Row Level Access Control Espresso or Corporate Authentication Provider ID, Credentials Active Server Authenticate Roles Espresso Logic Designer Role/Table Permission Filters Active Server Authorize Filters, injected into requests
- 16. Row/Column Security 1. 2. Filter applied to all GETs For all purchaseorder Resources
- 17. Reactive: the Executable Specification
- 18. Logic Events 1. Full Control 2. Domain/Object model (row)
- 19. Enterprise Integration 1. Request Events 2. Invoke RESTful service
