Advanced Espresso Logic

Addressing Complexity

Typical Use Cases

• Retrieval

– Row Events – computed attributes, filtering

– Power SQL – power when you need it

– JavaScript Resources – invoke Web Service

– Request Events – audit, pre-create data

• Update

– Basic REST

• Audit

• Bill Of Materials

• Allocation

– Advanced Rest

• Clone

• Give Raise(aPercent)

Row Events

• Add Derived Attributes

• Row Filtering

Power SQL

• Full Power of SQL

• URL Parameters

JavaScript Resources

• Compute response in JavaScript

• E.g., invoke RESTful service (integrate corporate data)

Request Events - TBD

• Audit Requests

Audit

• Server-side Java Script

• Row is Domain Object (order)

• Reuse Library

Bill of Materials – Price Rollup

• 4 Rules to Recompute kit price when component price changes

Bill of Materials – Kit Explosion

• 4 Rules to order all components of a kit, recursively

Bill of Materials – Kit Explosion (2)

• Reusable set copy

Allocate Payment to Orders

• Reusable rule extension

Allocate Payment to Orders (2)

• Reusable rule extension

• Recipient orders

• Creating

Allocate Payment to Orders (2)

• Reusable rule extension

• Recipient orders

• Creating

Clone - TBD

• Deep Copy

Give Raise - TBD

• Rest arguments
