This are very basic questions but the first one hasn't been asked for a long, long time.

1) Multiple options depending on what characteristic you wish to check. You can define the item as being numeric (if you only want numbers), you can define a length (if you only want so many characters), you can define a mask, you can write code in a When-Validate-Item trigger and use PL/SQL to interigate the data.

2) Parameters, global values, database objects - package variables, table items.

3) You can use either the 'default_where' facility (search this forum or read the documentation) or use the 'Query Data Source Type' of 'FROM clause query' (search this forum, read the documentation, or google them).
