to get the join/rules/join would look something like this
Register(new JoinLookups()
.Left(Partial
.Register(new JoinFileToDb()
.Left(new GetDataFromFile())
.Left(new GetDataFromDb()))
.Register(new ApplyBusinessRules()))
.Right(new GetLookups()))
.Register(new OutputOperation());
in this scenario the GetX() subclasses are a source of rows.
ApplyBusinessRules is an implementation of AbstractOperation and
OutputOperation is a final destination operation like
OutputDatabaseOperation.
when executed it will work like this:
1. get data from file
2. get data from database
3. join file to database
4. apply business rules
5. get lookups
6. join lookups to rows processed by the business rules
7. send to output operation
errors are collected as they occur in each operation. they are
available for inspection in the Errors property of each operation and
the EtlProcess. an EtlProcess implementation shouldn't throw an
exception itself.
