information about a column, the TriggerInfo class to obtain the information about
a trigger, and so on. Furthermore, the metadata information for a given database
object is added up in the class representing it. For instance, the TableInfo class
consists of a list of columns, a list of check constraints, and so on. Figure 5-6
show the class diagram used in our application.

Our application only uses a small subset of the DB2 metadata, and each class
contains only a subset of the information available for that particular database
object. For further details see the source code that can be downloaded from the
IBM Redbooks Web site. Refer to Appendix B, “Additional material” on page 267

5.5.4 Alternatives: DB2 tools
An alternative is to use a migration tool to migrate one database to another.
These tools are usually comprehensive and require some manual steps and user
interactions. One of these tools are the DB2 Migration Toolkit. The primary
purpose of this tool is to migrate a non-IBM database such as Oracle or MSSQL
into an IBM database — either DB2 or Informix. However, it is also a possibility to
use the DB2 Migration Toolkit for the purpose described in this chapter. You can
read more about the DB2 Migration Toolkit at:

5.6 Samples overview
In this section we list all the scripts, command files, and Java programs we
present in this chapter. We refer to “a script” as a text file containing DDL and
SQL statements; “a shell script” as a command file at the operating system level.
