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 Mobile SDK. We'll develop a simple app using SmartStore offline storage, highlighting the 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.

REST API Returns a JSON Response/services/data/v29.0/query/?q=SELECT Id, Name FROM Contact 17. Soups and Stores 18. 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 19. IndexSpec JSON Object Fields to index string or integer [ {"path":"Id","type":"string"}, {"path":"Name","type":"string"} ] 20. QuerySpecbuildAllQuerySpec(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 valuesbuildLikeQuerySpec(path,likeKey,order,pageSize)Basically select * from [table] LIKE %[likeKey]%buildSmartQuerySpec(smartSql,pageSize)Basically select * from [table] LIKE %[likeKey]% 21. SmartSQLSELECT {departments:name}, {employees:lastName}FROM {employees}, {departments}WHERE {departments:deptCode} = {employees:deptCode}ORDER by {departments:name}, {employees:lastName} 22. SmartSync 23. SmartSync Extends Backbone.js Can be used with or without a SmartStore Cache Queries returned as Backbone Model Collections 24. 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 25. 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: backup data for conflict detection 26. Force.SObjectCollection config: determines queries used to access data cache: if using SmartStore cacheForOriginals: backup data for conflict detection 27. Force.StoreCache soupName: Name of the SmartStore Soup additionalIndexSpecs: IndexSpecs to use, in addition to defaults keyField: Name of the field containing the record Id __locally_created__ __locally_updated__ __locally_deleted__ __local__ (set to true if any of the previous three are true) 28.
