Create db.properties
THis file contains some basic propertties
# properties for working with iBatis SqlMaps to access the `derby local demo` database # compulsory # driver=org.apache.derby.jdbc.ClientDriver # class anme of your driver code # # optional, also in repository settings #url=jdbc:derby:C:\DerbyDatabases\MyDB;create=true # optional url of your DB # user=APP # user name password=secret # password also in dialog

Create SQL statements for Repository conaining legal values
Create SQL statements to return legal Owners, legal Products, legal Issue States, legal Priority values for the query lists and combos.
Also add code to validate and initialize the database when relevant. Default is not to allow initialization.

Create SQL statements for handling basic Tasks
Create similar queries for fetching tasks meeting criteria and individual tasks

Create SQL statements for handling Comments and Attachments
When starting all of these can be empty statements, ensure you get the tasks listed properly first.
