There are many ways to integrate an Android app with an Amazon Web Services database. This presentation explores some of those possibilities and the choices I made for my app using the AWS SimpleDB NoSQL cloud database.

1. Integrating an App with Amazon Web Services SimpleDB “ A Matter of Choices” Presented by Mark Maslyn – mmaslyn@msn.com

2. Amazon Web Services Menu

5. SimpleDB Language Support

13. Example NoSQL Row For Geologic Formation Names and Depths Item Key “ 05-10123”, “BLAINE”, “1464”,”ATOKA”,”4744”,”MORROW”,”4854” Name3 Name2 Name1 Value1 Value2 Value3

15. Connecting to Amazon SimpleDB private static AmazonSimpleDB sdb = null; public static AmazonSimpleDB getInstance() { if ( sdb == null ) { // pass in the authenication credentials sdb = new AmazonSimpleDBClient( AWSDemo.credentials ); // set the node we want to use sdb.setEndpoint("sdb.us-west-1.amazonaws.com"); } return sdb; }

16. Creating SimpleDB Domains From Android public void createDomain(String domainName) { sdb.createDomain( new CreateDomainRequest(domainName)); }

17. Inserting Records From Android // each row is keyed with a “replaceable” item id followed by // attributes i.e. name / value pairs // construct a list of items to be inserted List<ReplaceableItem> dataList = new ArrayList<ReplaceableItem>(); // populate the list using the item id and the attribute name / value pairs dataList.add( new ReplaceableItem(“05-123”).withAttributes( new ReplaceableAttribute(DBFields. STATE , “CO”, true ), new ReplaceableAttribute(DBFields. COUNTY , “Weld”, true ), new ReplaceableAttribute(DBFields. DRILLING_DATE , “05-11-2011”, true )); // batch insert the list into the SimpleDB database sdb.batchPutAttributes( new BatchPutAttributesRequest( “my_domain” , dataList ));

18. Retrieving Data From Amazon // build your SQL select statement String selectExpression = &quot;select * from &quot; + domain + &quot; where itemName() = '“05-123’”; // construct a select request SelectRequest selectRequest = new SelectRequest(selectExpression); // retrieve a list of matching items (records) List<Item> itemList = sdb.select(selectRequest).getItems(); // loop through each record and extract the attributes from each item for ( int i = 0; i < itemList.size(); i++) { Item item = (Item) itemList.get(i); ArrayList<Attribute> attributeList = (ArrayList<Attribute>) item.getAttributes(); }

19. Question: Since Android Devices Can Use the Internal SQLite Database… When I Would I Use the Internal Database and When Would I Use the Amazon Cloud Database ?
