public final class DatabaseProduct extends Object
DatabaseMetaData.getDatabaseProductName()
.
Ideally we shouldn't have to take care of Database specificities since we're using Hibernate to abstract ourselves from Databases. However it happens that Hibernate doesn't support setting Catalogs on some databases and instead we need to use our own tricks to do that and these tricks depend on the database. Hence the need to differentiate them and hence the need for this class.

public static final DatabaseProduct DB2
Per DB2 documentation at
http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/topic/com.ibm.db2.luw.apdv.java.doc/doc/c0053013.html, the
database product name returned by the DatabaseMetaData.getDatabaseProductName()
method of DB2
JDBC drivers varies by the OS and environment the product is running on. Hence the DB string here uses only the
first 3 unique characters of the database product name. The toProduct(String)
method also hence checks
for String.startsWith(String)
rather than an exact match.
