  • Hi,

    I am developing a SmartStore android app. What I need to do is 'when my device goes from offline (not connected to internet) to online (connected to internet) then the data which I stored offline should get uploaded to salesforce automatically.

    Thanks,
    Swayam

  23. 23. REST API HEAD is used to retrieve resource metadata. GET is used to retrieve information, such as SOQL Queries using SELECT. POST is used to create a new record. PATCH is used to update or upsert a record. DELETE is used to delete a record.

  26. 26. SmartStore Stack
  27. 27. Smartstore Security Only cross-platform NoSQL mobile database technology on the market that comes with encryption built right in. And if you’re doing a hybrid (Phonegap) app…
  28. 28. WebSQL http://caniuse.com/#search=websql
  29. 29. IndexedDB http://caniuse.com/#search=indexeddb
  30. 30. PhoneGap Storage Class
  31. 31. Native Database Technology Encryption • Encrypt your data yourself using PIN / Passcode • CoreData/SQLCipher  NSIncrementalStore  Good Dynamics • FMDB/SQLCipher  Salesforce Smartstore
  32. 32. Terminology Soup – is a database table used to store JSON documents with index columns. Soups are held in Stores, which are SQLite database files. This is all Apple Newton terminology  It had no real filesystem, so data was stored in database entries called “soups”  For the interested: • http://en.wikipedia.org/wiki/Soup_(Apple) • http://www.canicula.com/newton/prog/soups.htm
  33. 33. 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
  34. 34. IndexSpec • JSON Object • Fields to index • “string” or “integer” [ {"path":"Id","type":"string"}, {"path":"Name","type":"string"} ]
  35. 35. 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]%’”
