Coarse Grained SOA:

Services are also could be coarse grained. E.g:   You may have a purchase element with individual functions to make a purchase order, add line items, and a customer element to set the customer information etc. calling these individual functions locally would not cause any problem but if you use remote service invokes then performance causes can be evident. The solution is for the service to give a single method call to prepare an order, add line items and set the customer details adding a façade design pattern by getting a single DTO (Data Transfer Object) or an XML containing the full data base structure for the entire order.
