Perchè potresti avere bisogno di un database NoSQL anche se non sei Google o Facebook Luca Garulli

2.
The graph db for the Enterprise & Web www.orientechnologies.com

3.
Why do I could 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.
Can I trust new DBMSs? www.orientechnologies.com

Java ® runs everywhere is available JRE1.5+ robust engine www.orientechnologies.com

24.
150,000 records per second www.orientechnologies.com

25.
Schema- less schema is not mandatory, relaxed model , collect heterogeneous documents all together www.orientechnologies.com

26.
Schema- full schema with constraints on fields and validation rules Customer.age > 17 Customer.address not null Customer.surname is mandatory Customer.email matches '[A-Z0-9._%+-]+@[A-Z0-9.-]+[A-Z]{2,4}' www.orientechnologies.com

27.
Schema- mixed schema with mandatory and optional fields + constraints the best of schema-less and schema-full modes www.orientechnologies.com

28.
ACID Transactions db.begin(); try{ // your code ... db.commit(); } catch( Exception e ) { db.rollback(); } www.orientechnologies.com

29.
Complex types native support for collections : ['cool','fast'] maps (key/value): { 'age', 33 } and embedded documents no more additional tables to handle them www.orientechnologies.com

30.
Relationships are direct links no Relational JOINS to connect multiple tables Load trees and graphs in few ms ! www.orientechnologies.com

31.
Example of a Graph www.orientechnologies.com

32.
SQL select * from employee where name like '%Jay%' and status=0 www.orientechnologies.com

33.
www.orientechnologies.com A NoSQL product that supports SQL ? Naa... is it a joke?

34.
www.orientechnologies.com For the most of the queries everyday a programmer needs SQL is simpler, more readable and compact then Scripting (Map/Reduce)

35.
www.orientechnologies.com SELECT SUM(price) as prices, SUM(cost) as costs, prices-costs, margin/price FROM Balance VS function (key, values) { var price = 0.0, cost = 0.0, margin = 0.0, marginPercent = 0.0; for (var i = 0; i < values.length; i++) { price += values[i].price; cost += values[i].cost; } margin = price - cost; marginPercent = margin / price; return { price: price, cost: cost, margin: margin, marginPercent: marginPercent }; }

36.
For Relational skilled Developers (everyone of us?) using OrientDB is easy www.orientechnologies.com

37.
Asynchronous Query invoke callback when a record matches the condition doesn't collect the result set perfect for immediate results useful to compute aggregates www.orientechnologies.com

38.
Language bindings Java as native JRuby , Scala and Javascript ready C , C++ , Ruby , Node.js in progress www.orientechnologies.com

39.
Your language is not supported (yet)? Write an adapter using the C, Java or HTTP binding www.orientechnologies.com

40.
HTTP RESTful firewall friendly use it from the web browser use it from the ESB (SOA) www.orientechnologies.com

41.

61.
Use hooks (triggers) public class HookTest extends ORecordHookAbstract { public saveProfile(){ ODatabaseObjectTx database = new ODatabaseObjectTx(&quot;remote:localhost/demo&quot;); database.open(&quot;writer&quot;, &quot;writer&quot;); database.registerHook(this); ... } @Override public void onRecordAfterCreate(ORecord<?> iRecord){ System.out.println(&quot;Record created successfully&quot;); } } www.orientechnologies.com
