Magic multi-tenant generic data modeling
 core.name_denorm
– Single table with the name of all entities
 core.seach_name_lookup
– Single table with all pivoted name components (for search)
 core.custom_index_value (and custom_unique_value)
– Pivoted, de-normalized physical indexes (native data types)
 core.custom_foreign_value
– Reverse lookups for any foreign key
 core.clob_data
– Pivoted clob values, maintained efficiently

Optimized Response
Optimizer example: Entity v Boss v “Peon”
SELECT name FROM Account WHERE Status = ‘Red’
 For a given query, at least 3 possible plans
– Entity driven filter: standard or custom index (join) driven
– Peon driven sharing: use nested loop sharing-driven (2 joins) plan
– Boss plan: use hashing sharing plan (hash semi-joins)
 Statistics we must track
– Size of the entity for the organization
– Approximate visibility by user to this entity
– Statistics of various field fields (custom indexes)
• For domain fields: which values are high-cardinality?
• If we don’t know, pre-query with ROWNUM
Declarative versus Procedural
Business users can get a lot done without coding
Data validation
Formula fields and summaries
State Machine workflows
Multi-Step approvals
Automatic email approvals
Audit history tracking
100% automatic upgrades
Real Apps Require Procedural Code
The case for Apex (384,000 lines and growing)
• Transactional Logic, over a Web Service
• Stored Procedures, Triggers
• Reliable DML Upgrade Scripts
• Executing on our Servers
• Must protect the site
• Strongly typed
• Persist schema references
• Much more natural than JDBC
• Preserved through Upgrades
• Code Coverage and Testing built-in
• Web Service Exposure (In and Out)
But why a new language?
 We considered the alternatives
– Java? (JDBC is a lousy interface for this)
– JavaScript (Rhino)? Other scripting language? (not db focused)
– Existing stored procedure languages? (ugly)
 Advantages of writing our own
– We control the syntax: deep salesforce.com integration
• Our idioms, our schema binding, our ecosystem
– We control the runtime: control resources and coding behavior
– We can ease the transition: looks like Java, acts like Pl/Sql
– It’s not that hard to do: Java VM makes a great VM container
 But we have a high bar to match…
– Modern language features, modern IDE’s
Database-focused
Strongly typed
Schema Aware

Object Oriented

Apex Code “Big Brother” Best Practices
 Governor limits enforce efficient coding styles
– No SOQL inside of a for loop
 Required functional testing
– Built into the language
– Coming soon: requirement to test in bulk
 Required code coverage
– Inability to deploy to production without it
 Higher bar for 3rd ISV’s than IT developers
We can (almost) prove that our releases won’t break
production applications
Areas of Active work and research
 Next level of expressiveness across the platform
– Richer semantics for virtual schema design, SOQL and Apex
– Provide a custom scheduler, flesh out VisualForce components
– Complete the on-demand development tools
• Debugger: what to do about transactions?
 Managed code correctness
– Deadlock detection best practices
– Dynamic-SOQL and reflection in Apex
 Operational next generation architecture
– Oracle 10g, 11g, much cheaper Pods, cheaper storage, high-latency
data center communication
– Database replication, zero-down time releases (Call Centers)
