This document discusses using Doctrine 2 as an ORM with Zend Framework 1.10. It explains what Doctrine is, why it should be used, and how to set it up with Zend Framework. It provides examples of inserting records with Doctrine 2 versus raw PHP code, showing Doctrine 2 is faster due to transaction handling. It also demonstrates how to configure a blog module with Doctrine 2, define entities, generate the schema, and perform basic CRUD operations.

2. What is Doctrine?
Doctrine is a popular ORM for PHP which works
with RDBMS via PHP objects. This is built inspired
by Hibernate from JAVA. This acts as an abstraction
layer between PHP and RDBMS.

3. Why should I use it?
- Because Nurul Ferdous
said?
- Does it solve the world
terrorism problem?
- No, don't be mad on
me :) I am gonna
explain it.

4. to SQL or NoSQL!
- MySQL
- Oracle
- PgSQL
- SQLite
- MsSQL
- IBMDB2
- etc
- MongoDB
- CouchDB

5. Inserting 20 records with Doctrine

6. Compare it to some raw PHP code

7. Insert performance
Doctrine 2 = 0.0094 seconds
mysql_query = 0.0165 seconds

8. Doctrine 2 is faster than raw PHP???
Why? The answer is transactions! Doctrine
2 manages our transactions for us and efficiently
executes all inserts in a single, short transaction. The
raw PHP code executes 1 transaction for each insert.

9. Here is the same raw PHP code with
proper transaction usage

10. Insert performance
* Not trying to say Doctrine 2 is faster than raw PHP
code
* Demonstrating that simple developer oversights
and mis-use can cause the greatest performance
problems
* This time around it only takes 0.0028 seconds
compared to the previous 0.0165 seconds. Pretty
cool, huh!

15. Working with code is often boring.
Please don't sleep and bear with me

16. Configuration for blog module

17. A typical blog Entity in Doctrine 2

18. Generating schema from CLI
