What is a “Social Enterprise Application?”

MOBILE Architecture must account for mobile as primary UI device

SOCIAL Taking maximum advantage when “social”-izing apps

OPTIMIZED Accessing ever-larger cloud-based data sources

Development Trends -Mobile

The New Architecture for Mobile Apps

1980s: Desktop apps

• Complex processing• Rich user experience• Connectivity not required• Examples: MSFT Office, Adobe Photoshop

1990s: Client-server• Desktop apps paired with a server• Complex local architectures• Examples: SAP, Oracle Apps

2000s: Web and RIAs

• Browser as universal HTML client• Rich UI and media; server does most logic• Examples: Web editions of enterprise

software

2011+: Mobile• Maximize use of local CPU• Minimize need for data throughput• Examples: Database.com

The New Mobile Architecture Requires a Different Approach

App Server


SOAP?REST?

HTML5?Native (iOS, Android)?

Development Trends -Social

Does Your App Have Social Graces?

Phase 1: “Socially Enabled”

Chatter feed on business objects


Phase 1: “Socially Enabled”

Chatter feed on business objects

Where should users look for the narrative?

• Record History• Notes & Attachments• Activity History• Chatter Feed• All of the above?

Considerations• “Force” feed• Drop followers at close


Phase 2: “Socially Witty”

Have something interesting to say


Phase 2: “Socially Witty”

Considerations• Give your app a distinctive “voice”• Go beyond basic field changes

Phase 3: “Socially Aware”

Securing Cloud Data

Database.com provides a rich, row-level security model– Powering our CRM application for 10+ years

– Separates the administration of security rules from application development

Query / Search natively support security model– Inaccessible records are automatically filtered out

Multi-Tenant Query Optimizer ensures security handled efficiently

Run pre-queries

Check user Visibility

Check filter selectivity

Write query-based on

results of pre-queries

Execute query

Apex REST (Pilot)

APEX Web Services exposed via REST– Allow for custom built web services to be exposed by

customers and partners using REST architecture

– Well suited for Mobile and Cloud applications

Annotation in the APEX class:– @RestResource , @HttpGet, @HttpPost, @HttpPatch, @HttpDelete

Support XML and JSON formats

Apex Rest (Pilot)@RestResource(urlMapping='/CaseManagement/*')global with sharing class CaseManagementRESTSvc {

@HttpGetglobal static Case getCaseRecord(RestRequest req, RestResponse res) {

String caseNum = req.requestURI.substring(req.requestURI.lastIndexOf('/')+1);

Case c = [select id, CaseNumber from Case where caseNumber = :caseNum];

return c;

}

@HttpPostglobal static Case createCaseRecord(RestRequest req, RestResponse res) {

CompositeCaseRecord compositeCaseRec = new CompositeCaseRecord();

Case c = CreateCustomCaseRecord.createCase(compositeCaseRec);

return c;

}

@HttpDeleteglobal static void deleteCaseRecord(RestRequest req, RestResponse res) {

String caseNum = req.requestURI.substring(req.requestURI.lastIndexOf('/')+1);

Case c = [select id, CaseNumber from Case where caseNumber = :caseNum];

delete c;

}

}

Apex Rest (Pilot)public with sharing class CreateCustomCaseRecord {

public static Case createCase( CompositeCaseRecord caseRecord )

{

Savepoint sp = Database.setSavepoint();try

{

Case c = new Case();

c.Status = 'New';

Account a = new Account (Backend_Acct_Number__c = caseRecord.acctNumber);

c.Account = a;

insert c;

c = [select id, CaseNumber, subject, Description, Priority from Case where id=:c.Id];

Labor__c labor = new Labor__c();

labor.Case__c = c.id;

labor.Rate__c = caseRecord.labor_rate;

insert labor;

return c;

}catch (Exception e)

Real-time Cloud Apps

Streaming API (Pilot)

Provide a stream of updates based on data changes– Admin define topics via continuous queries

– System runs queries based on a Topic

– Relevance matching kicks in and fetch updates

– Clients subscribe to Topics and listen for updates

Use Cases includes:– Near real time updates: Call Centers, Financial Apps, Calendar

– Data synchronization – immediate updates

– General purpose notifications upon saves and deletes

– Push notifications to mobile devices

Optimizing Cloud Applications

Large Data Volumes

Bulk API Query

Allow for data to be retrieved via SOQL query– Up to 10 files of 1Gb each file – total of 10Gb

– Query can run for up to 10 attempts, at 10 minutes each

– Results are kept for 7 days in system

– Supports XML and CVS formats

– View results on Monitoring Page

Allow for full LDV lifecycle of data in/out of Salesforce

Scaling Apex Triggers

Basic Trigger Architecture (Bulkification)– Preprocessing

• Query needed rows

• Arrange into data structures

– “The Main For-Loop”• Use a main for loop to ensure that no records are left behind

• Avoid queries and DML operations within for loops

– Clean up and final steps• DML operations

• Emails/Notifications

Asynchronous Processing

NOW

vs.

LATERMove processing that is large or not immediately needed by the user to async

• Avoid limits• Better usability• Higher through-put

Scaling to Large Data

Asynchronous Apex– @Future methods

• Lightweight

• Easy to use (simple method annotation)

• Great for smaller transactions

– Batch Apex• Heavy duty (interface to implement)

• Can process up to 50M rows

But wait, the DevZone has more!
