I had been following his blog regulalry and he is a heck of smart guy and one can definitely learn so much about web analytics. Avainahs is co founder of online learning learning startup Market Motive, which will help you to learn and expertise in the field of SEO. Market Motive offers  three month structured course (with exams and quizzes) and costs $3500.

It may not pinch US and Europeans (although with plunging value of pound and Euro , I think it might !!) but is definitely a big investment for Asian community.

Pricing aside , if you look the the faculty, it is impressive and I think it would be worth your money. One cannot learne everything by reading from the book.

Good luck Avinash with this new venture.

1. Primary key association:
2. Foreign key association.

My previous post described about the Primary key one-to-one mapping in Hibernate. This post gives an example of Foreign key one-to-one association in Hibernate.

In Foreign key one-to-one mapping,  2 entities will have one to one association using foreign keys. one  table holds primary key of 2nd table. Eg: consider Customer and address entities. In primary key association,  both the tables share same primary key. In foreign key association, customer table will have a address_id columns, in which primary key (address_id) of the customer’s address will be saved. Both customer and address tables will have different primary keys.

The tables would look like below:

create table address(
    address_id int(11) not null auto_increment,
    address_line1 varchar(100) not null,
    address_line2 varchar(100),
    city varchar(50) not null,
    state varchar(50) not null,
    pincode int(10) not null,
    primary key(address_id));

create table customer(
    customer_id int(11) not null auto_increment,
    name varchar(50) not null,
    email_id varchar(100),
    contact_no varchar(20),
    address_id int(11),
    primary key(customer_id),
    foreign key(address_id) references address(address_id));

Address is a simple table and customer table contains a column to store the corresponding address_id.

Corresponding Beans would be with following fields and their getter and setter methods:

public class Address {

 long addressId;
 String addressLine1;
 String addressLine2;
 String city;
 String state;
 Integer pincode;
 Customer customer;

public class Customer {
 Long customerId;
    String name;
    String emailAddress;
    String contactNo;
    Address address;

The Hibernate mapping files would look like below:

Address.hbm.xml:

<?xml version=”1.0″?>
<!DOCTYPE hibernate-mapping PUBLIC
“-//Hibernate/Hibernate Mapping DTD 3.0//EN”
“http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd“>

<hibernate-mapping>
  <class name=”entities.Address” table=”ADDRESS”>
    <id name=”addressId” type=”long” column=”address_id” >
     <generator/>
  </id>
  
  <property name=”addressLine1″>
     <column name=”address_line1″ />
    </property>
   
    <property name=”addressLine2″>
     <column name=”address_line2″ />
    </property>
   
    <property name=”city”>
     <column name=”city” />
    </property>
   
    <property name=”state”>
     <column name=”state” />
    </property>
   
    <property name=”pincode”>
     <column name=”pincode” />
    </property>
  </class>
</hibernate-mapping>

address.hbm.xml is simple and there is no much complications.

Customer.hbm.xml:

<?xml version=”1.0″?>
<!DOCTYPE hibernate-mapping PUBLIC
“-//Hibernate/Hibernate Mapping DTD 3.0//EN”
“http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd“>

<hibernate-mapping>
  <class name=”entities.Customer” table=”CUSTOMER”>
    <id name=”customerId” type=”long” column=”customer_id” >
     <generator/>
  </id>
  
  <property name=”name”>
     <column name=”NAME” />
    </property>
   
    <property name=”emailAddress”>
     <column name=”email_id” />
    </property>
   
    <property name=”contactNo”>
     <column name=”contact_no” />
    </property>

    <many-to-one name=”address”
                column=”address_id”
                cascade=”all”  unique=”true”
                />
  </class>
</hibernate-mapping>

Point to note here is the Many-to-one tag. We are associating the entities with one-to-one but we are using a many-to-one tag. When using many-to-one in one-to-one mapping, we ignore the ‘many’ part. We are not caring how many address are bound to a customer, but here we ensure that only one customer (to-one part) is bound to an address.

In customer class, by defining the address variable as below:

 Address address;

 (As its not a List/Set or collection) we ensure that its just an one-to-one relationship.

 Now we can test it using following code:

// save customer
         Customer customer = new Customer();
         customer.setName(“Surya”);
         customer.setEmailAddress(“surya@gmail.com“);
         customer.setContactNo(“91-932686876″);
         Address address = new Address();
         address.setAddressLine1(“xxx-street, near Surya Complex”);
         address.setCity(“Pune”);
         address.setState(“Maharashtra”);
         address.setPincode(11111);
        
         customer.setAddress(address);
         address.setCustomer(customer);
         session.save(customer);

   //fetch all customers
           
            Query query = session.createQuery(“from Customer customer”);
            for(Iterator it=query.iterate();it.hasNext();){
             Customer customer1 = (Customer) it.next();
             Address address1 = customer1.getAddress();
                System.out.println(“customer ID: ” + customer1.getCustomerId());
                System.out.println(“Name: ” + customer1.getName());
                System.out.println(“address: ” + address1.getAddressLine1());
                System.out.println(address1.getAddressId());
                System.out.println(address1.getAddressLine2());
                System.out.println(address1.getCity());
                System.out.println(address1.getState());
                System.out.println(address1.getPincode());
              }

You can find spring training locations here…

http://mylearn.vmware.com/portals/springsource/search/findcourse.cfm?ui=s2

You need to get registered to see information on fees, location etc.

If you don’t want to go for spring training then you must have experience in working on spring. Spring source such candidates as ‘grandfathered’ candidates. You need to provide a ‘Grandfather Application’ providing proof of their experience on spring. Some more details are given below

Spring Framework is offered to two groups of people: those who have attended a 4-day Core Spring training course and those who haven’t attended the course but have gained knowledge of Spring from other sources, such as private study, client projects, forums etc.  We call this second group, ‘grandfathered’ candidates.

A grandfathered candidate is a person who has not attended the four-day Core Spring class but who has satisfied any one of the following criteria:

•             Demonstrable evidence of (1) successful Spring solution completed. Evidence will include customer name and contact information reference.

•             Demonstrable evidence of adding value to Spring Products and/or the Community. Candidate should provide supporting information from one or more of the following examples:

a. Forum post
b. Software patches
c. Articles promoting Spring or explaining Spring
d. User Group involvement

•             Possession of a Spring Framework Professional Certification from a previous version of Spring.

These are the only ways in which you can obtain a voucher in order to take the certification exam and become a Certified Spring Professional. More information including sample questions and costs can be found here: http://www.springsource.com/training/certification/springprofessional

Clck here to see the Grandfather Application.

Update : Danielbutcher has added a Spring Certification practice test.

Do you want Steve to cover some specific topic on business English ?

For $40 million , Prometric has done a very lousy job.  When students went in to take the exam on 28 Nov, the servers crashed. And not all of the 250,000 students were taking the test. It was only 20% of them.

The students who took the online Common Admission Test, some of them were not quite convinced about the new format of the examination. And their fears had come true.

Well 50,000 stduents concurrently taking test should not be a rocket science . Compare to ebay , Amazon and twitter which handle multiples of traffic every minute. Looks like prometric did not even bothered to conduct a pilot run.

No update on when the service will be restored and if IIM can afford to have this kind of glitch again.

This test will also help in Spring Certification exams

If you have some more questions to share , register or upgrade as a guru and add the questions.
