At some point, all mobile app users lose their data signal. Join us to learn best-practices for coding for offline requirements with the salesforce.com Mobile SDK. We'll develop a simple app using SmartStore offline storage, highlighting the new SmartSQL and SmartSync features. With these tools, you can take your mobile apps to the next level, developing native and hybrid applications on iOS and Android that have offline access to your data.

• Hold Indexed JSON Documents
• JSON Responses can encompass data from multiple tables
Id
Soup
Created
lastModified
Index 1
Index 2
Index N…

14. REST API Returns a JSON Response
/services/data/v28.0/query/?q=SELECT Id, Name FROM Opportunity

15. Stores

16. Some things you can do with your soup…
• Register a Soup with an IndexSpec
• Query a Soup using a QuerySpec
• Upsert Data to a Soup
• Delete Data from a Soup
• Remove a Soup

17. IndexSpec
• JSON Object
• Fields to index
• “string” or “integer”
[
{"path":"Id","type":"string"},
{"path":"Name","type":"string"}
]

18. QuerySpec
buildAllQuerySpec(path,order,pageSize)
Query all records from the object in the given sort order (or null order)
buildExactQuerySpec(path,matchKey,pageSize)
Search for records with index path values matching the key.
buildRangeQuerySpec(path,beginKey,endKey,pageSize)
Return all records with an index path value between the two range values
buildLikeQuerySpec(path,likeKey,order,pageSize)
Basically “select * from [table] LIKE ‘%[likeKey]%’”
buildSmartQuerySpec(smartSql,pageSize)
Basically “select * from [table] LIKE ‘%[likeKey]%’”

19. SmartSQL
SELECT {departments:name}, {employees:lastName}
FROM {employees}, {departments}
WHERE {departments:deptCode} = {employees:deptCode}
ORDER by {departments:name}, {employees:lastName}

20. SmartSync

21. SmartSync
• Extends Backbone.js
• Can be used with or without a SmartStore Cache
• Queries returned as Backbone Model Collections

22. Backbone
• MV* Framework
• Models: Individual records
• Collections: Collections of Model records
• View: Javascript backing for the stuff that you see
• Router: routes everything after the # in a URL to application functions
• http://myapp.com/#/user/list

23. Force.SObject
• sobjectType: Account, Opportunity, etc.
• fieldlist: ["Id", "Name", "Amount", "StageName"]
• cacheMode: client, server write order
• mergeMode: how to handle conflicts
• cache: if using SmartStore
• cacheForOriginals: for conflict detection

24. Force.StoreCache
new Force.StoreCache(soupName [, additionalIndexSpecs, keyField])
▪
__locally_created__
▪
__locally_updated__
▪
__locally_deleted__
▪
__local__ (set to true if any of the previous three are true)
