 ## What is OrientDB?
 
-**OrientDB** is an Open Source [NoSQL](http://en.wikipedia.org/wiki/NoSQL) DBMS with the features of both Document and Graph DBMSs. It's written in Java and it's amazingly fast: it can store 220,000 records per second on common hardware. Even for a Document based database the relationships are managed as in [Graph Databases](http://en.wikipedia.org/wiki/Graph_database) with direct connections among records. You can traverse parts of or entire trees and graphs of records in a few milliseconds. Supports schema-less, schema-full and schema-mixed modes. Has a strong security profiling system based on user and roles and supports [SQL](http://orientdb.com/docs/last/SQL.html) amongst the query languages. Thanks to the [SQL](http://orientdb.com/docs/last/SQL.html) layer it's straightforward to use for people skilled in the Relational world.

It's written in Java and it's amazingly fast: it can store 220,000 records per second on common hardware. No expensive run-time JOINs, connections are managed as persistent pointers between records. You can traverse thousands of records in a few milliseconds. Supports schema-less, schema-full and schema-mixed modes.

 ## Is OrientDB a Relational DBMS?
 
-No. OrientDB adheres to the [NoSQL](http://en.wikipedia.org/wiki/NoSQL) movement even though it supports a subset of [SQL](http://orientdb.com/docs/last/SQL.html) as query language. In this way it's easy to start using it without having to learn too much new stuff. OrientDB is a [Document Database](http://en.wikipedia.org/wiki/Document-oriented_database) but has the best features of other DBMSs. For example relationships are handled as in [Graph Databases](http://en.wikipedia.org/wiki/Graph_database).
+No. OrientDB adheres to the [NoSQL](http://en.wikipedia.org/wiki/NoSQL) movement even though it supports [ACID Transactions](https://orientdb.com/docs/2.2/Transactions.html) and [SQL](http://orientdb.com/docs/last/SQL.html) as query language.

 As Multi-Model DBMS, OrientDB could work as an extended Document Database and an extended Graph Database. Take a look at [OrientDB vs MongoDB](http://orientdb.com/orientdb-vs-mongodb/) for Document Databases and [OrientDB vs Neo4j](http://orientdb.com/orientdb-vs-neo4j/) to have a comparison with a popular Graph Database.

 ## Easy to install and use
 
-Yes. OrientDB is totally written in [Java](http://en.wikipedia.org/wiki/Java_%28programming_language%29) and can run on any platform without configuration and installation. The full Server distribution is about 1Mb without the demo database. Do you develop with a language different than Java? No problem, look at the [Programming Language Binding](http://orientdb.com/docs/last/Programming-Language-Bindings.html).
