The Client also has a Servlet which can be accessed by browser
clients. These browser clients use the Web services of the client to
access the Web Services of
the Server and thus multiple client customers can transact in the online
retail store concurrently. There can be multiple instances of the Web
Client, each of which
can serve multiple customers concurrently, all accessing the same Retail
Application Server.
We refer to this as 1st Level Client Web Services.
This model can easily be extended in a similar fashion to another level of clients, 2nd Level Clients, who publish their services based on the 1st level client web services. Both these scenarios are depicted in the diagrams below.
This solution is hierarchical and flexible and scalable. At the same time, it preserves consistency in concurrent client access of a retail database at the Retail Application server.
