Querying multiple tables

Hi

I have 4 tables:

1) Owner Table - rcaowm - having own_code, owm_name
2) Tenant Table - rcatnm - having tnm_code (owner's code), tnm_acno
(tenant's account number), tnm_name
3) Owner Transactions - rcaowt - having owt_code (owner's code),
owt_date, owt_value
4) Tenant Transactions - rcatnt - having tnt_code (owner's code),
tnt_acno (tenant's account number), tnt_date, tnt_value

I want to produced a query giving the following data:

Owner_Name, Tenant_Name, Sum_Owner_Transaction_Value,
Sum_Tenant_Transaction_Value

Is there any way this can be achieved with a single select statement??

Thanks

Paul
