2. Q7 – How can organizations connect computer programs? Some companies find it advantageous to have programs on their computer systems directly access programs on other companies’ computers by using remote computing, also call distributed computing. One option is to develop proprietary distributed applications. – Teams from both entities work together to Determine application requirements, develop a design, and write and test the programs. Decide on communications capabilities, operating systems, and distributed computing techniques. – These types of systems are difficult and very expensive to develop and operate because of the vast amount of coordination necessary to make them work.

3. Q7 – How can organizations connect computer programs? An emerging Internet-based technology that companies are turning to for remote/distributed computing is called XML Web services. These services use a service-oriented architecture (SOA). Web services offer these advantages: – They provide a standardized way for programs to access one another remotely without proprietary solutions. – Standardization leads to the immediate accessibility of the services. – Service descriptions on one computer provide other computers with information about available programs and how to communicate with them. – XML documents transmit the service data and define the XML schema; program components of the XML Web services automatically validate the data.
