The document discusses how NoSQL databases like OrientDB can improve web application development compared to traditional relational databases. OrientDB provides a fast, scalable, and flexible storage solution with transactions, SQL, and security. It combines the best features of newer NoSQL solutions with relational databases. OrientDB supports document, graph, and object-oriented data models and can be used for both online backup solutions and CRM applications. It also introduces OrientWEB.js, a new JavaScript library for building web applications with OrientDB.

2. What?!!! How a DBMS can improve the development of Web Applications ? www.orientechnologies.com

3. ...And... Why Web Applications would need something different than a Relational DBMS? www.orientechnologies.com

4. (1) RDBMSs have more than 30 years Information Technology is not properly the same of '70 ... www.orientechnologies.com

5. (2) In the Web age applications could have Thousands or Millions of users Are you ready for this? www.orientechnologies.com

6. (3) Time-to-Market measured not anymore in years/man but days/weeks for a demo and months for the final www.orientechnologies.com

7. (4) Applications are more “ social” with much more relationships - tabular data and + interconnected Graphs www.orientechnologies.com

8. (5) Who believe yet to the bullshit that performance problems can be resolved just by scaling with the hardware? www.orientechnologies.com

9. (6) We use new stuff everyday HTTP , REST , Javascript & JSON How can I use them in better way without conversions & mapping? www.orientechnologies.com

10. (7) Modern applications are mostly I/O Bound not CPU bound. Often the DB Is the bottleneck of all www.orientechnologies.com

11. www.orientechnologies.com NoSQL = “Not Only SQL” = make the best choice for your use case

12. www.orientechnologies.com Non exhaustive list of NoSQL products: AllegroGraph, Amazon SimpleDB, Amazon Dynamo, Dynomite, BerkleyDB, Google BigTable, Cassandra, CouchDB, DB4O, Hbase, Hipertable, Hive, Jackrabbit, InfiniteGraph, InfoGrid, Memcached, MemcacheDB, Mnesia, M/DB/DT.M, MongoDB, Neo4J, OrientDB , Pig, Project Voldemort, RavenDB, Redis, Riak, Scalaris, Sesame, Sones, Terrastore, Tokyo Cabinet/Tyrant, Yahoo! Pnuts/Sherpa

13. www.orientechnologies.com The “NoSQL container” groups so very-very-very different products, no standard, difficult to choice, difficult to learn them

14. www.orientechnologies.com Can I have a Fast, scalable, flexible storage with transactions , SQL and security easy to use and maintain?

41. Binding Object ↔ Form Binds automatically complex JSON to HTML and vice-versa Conventions over Configurations Developer has full control about customization, just respect naming conventions on <tag> ids www.orientechnologies.com

42. bindObject2Form() <div id=&quot;contacts&quot;> <div>Contacts: <div> Name: <input id=&quot; contacts_?0 _name&quot;></input> Surname: <input id=&quot;contacts_?0 _surname &quot;></input> Phone: <input id=&quot;contacts_?0_phone&quot;></input> <div id=&quot;address&quot;>Address:</div> <div id=&quot; contacts_?0_address &quot;> <div> City <input id=&quot; contacts_?0_address_?1_city &quot;></input> Number <input id=&quot;contacts_?0_address_?1_houseNumber&quot;></input> Postal Code <input id=&quot;contacts_?0_address_?1_cap&quot;></input> Location <input id=&quot;contacts_?0_address_?1_road&quot;></input> <button id=&quot;contacts_?0_address_?1 !remove &quot;>Remove address</button> </div> </div> <button id=&quot;contacts_?0_address !add &quot;>Add address</button> <button id=&quot;contacts_?0 !remove &quot;>Remove contact</button> </div> </div> </div> www.orientechnologies.com Array Recursive fields 2 level arrays Actions

43. Object2Form binding $(function(){ // EXECUTE THE QUERY var result = database.query('select * from Company where name = 'Asset''); // CREATE THE FORM BINDING THE FIRST OBJECT OF THE RESULT SET var obj = result['result'][0]; form = new OForm(); form.object2form(obj); } function save(){ var obj = form.form2object() ; database.save(obj); } www.orientechnologies.com

44. What about security? www.orientechnologies.com

45. Security at schema level OUser can have multiple ORole Permissions are setted against ORole Resource + OPERATION {Create, Read, Update, Delete} Employee.create = false user 'reader' can't UPDATE records of class 'Employee' www.orientechnologies.com

46. Record level security Very similar to UNIX File System access Enabled if user class extends OSecureRecord Class OSecureRecord { OUser owner; ORole group; char[] access; // User, Group, Others } Class Employee extends OSecureRecord www.orientechnologies.com

47. More on OrientWEB.js Fully integrated with OrientDB JS driver : - preserves internal field like @class, @rid - uses field types if declared (schema-full) www.orientechnologies.com
