This statement obviously is wrong.

- Quality is only a function of time put into development.
- Functionality is the same.
- Performance of object databases is clearly by far superior to relational

databases for certain tasks. You are invited to benchmark the insertion performance of our database engine against any relational competitor of your choice. How about inserting 100 Contract objects of the following class model? Customer objects are to be inserted as well:

public class Document
{
 public String title;
 public Date creationDate;
}

public class Contract extends Document
{
 public String contractNo;
 public String subject;
 public Customer customer;
}

public class Person
{
 public String name;
}

public class Customer extends Person
{
 public String customerNo;
}

Please do publish the results here.
Inclusions of relational vendor names would be great.

If you get anywhere near 1000%, you have found a good one.

One hint:
All necessary code is available for download with our engine.

Kind regards,
Carl
