OrientDB for real & Web App development
1. for real & Web App development www.orientechnologies.com NoSqlDay – Brescia, Italy 2011
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
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?
22. 100% compliant with TinkerPop Blueprints standard for GraphDBs Support for GREMLIN Graph language Several Graph algorithms available www.orientechnologies.com
23. SQL & relationships select from Account where address .city.country.name = 'Italy' select from Account where addresses contains ( city.country.name = 'Italy') www.orientechnologies.com
24. SQL & trees/graphs select from Profile where friends traverse(0,7) ( sex = 'female' ) (Soon new specific operators for trees and graphs) www.orientechnologies.com
25. SQL & strings select from Profile where name .toUpperCase() = 'LUCA' select from City where country.name .substring(1,3).toUpperCase() = 'TAL' select from Agenda where phones contains ( number .indexOf( '+39' ) > -1 ) select from Agenda where email matches 'A-Z0-9._%+-?+@A-Z0-9.-?+A-Z?{2,4}' www.orientechnologies.com
26. SQL & schema-less select from Profile where any() like '%Jay%' select from Stock where all() is not null www.orientechnologies.com
27. SQL & collections select from Tree where children contains ( married = true ) select from Tree where children containsAll ( married = true ) select from User where roles containsKey 'shutdown' select from Profile where tags in 'cool' select from Graph where edges .size() > 0 www.orientechnologies.com
28. SQL & documents select from Vehicle where @class = 'Car' select from Friend where @version > 100 select from File where @size > 1000000 www.orientechnologies.com
30. Case Study #1 Online Backup solution built on top of OrientDB Operates in Austria, Swiss, Germany www.orientechnologies.com
31. Cluster of 6 servers 450 millions of records RAID 5 and 6 18TB of data expected 50TB next months www.orientechnologies.com
32. Double usage of OrientDB as GraphDB for the agents and as Binary repository for the Server-side cluster www.orientechnologies.com
33. www.orientechnologies.com * Agent: Virtual File System as Graph * VResource VFile VDirectory VChunk -------------- hash: string content : byte[] “ Chunks” as pieces of file max 64Kb, hashed (SHA-256) to avoid duplications of data for common files EntryPoint
37. Main goals (1) improve scalability (2) improve user's experience (3) simplify development (4) avoid constraints to web designers www.orientechnologies.com
38. What is OrientWEB.js ? Lightweight Javascript library Client-side only Based on HTTP, JSON and Graphs Under development, first alpha on April 5 th 2011 www.orientechnologies.com
39. Use the client resources to render the pages Unload the server from the heavy task of generating HTML Pages Reduce network transfer & latency The idea is not so new but revamped using new technologies... www.orientechnologies.com
40. www.orientechnologies.com HTTP GET /sql/select from company where name.startsWith( 'Asset' ) { @class = 'company', @rid = '9:34', name : 'Asset Management', address : { location : 'Via Rhodesia, 34', city : { name : 'Rome' } } } HTTP PUT /document/9:34 Browser/Server messages Agent WWW OrientDB Server
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
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
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
48. Always Free Open Source Apache 2 license free for any purposes, even commercials www.orientechnologies.com
