    Help understanding Martin Fowler's Remote Facade Pattern

    Posted: 05 Jan 2018 01:50 PM PST

    Hey guys.

    I'm in the process of understanding exactly what Martin Fowler's Remote Facade Pattern actually is and how it's used in practice.

    Link to Martin Fowler's definition and the address example I'll be using: https://martinfowler.com/eaaCatalog/remoteFacade.html

    I understand that the intention of the Remote Facade Pattern is to limit the traffic and the amount of calls made over the network, so instead of calling 3 methods separately over the network to set the address, you should make a Remote Facade that includes a single method to set all the data for the address.

    The problem is that my teacher has given me the impression that a Remote Facade needs to be made on the client and not the server, but if the server only makes available 3 separate methods for setting all the address data and doesn't have a single method that combines the job, then I can make a single method on my client that calls all 3 methods on the server, but that won't result in any less traffic being sent, because 3 methods still have to be invoked over the network.

    Is it wrong that the Remote Facade needs to be on the client and not the server or am I missing something?

    In case it makes any difference, in terms of client/server I'm thinking about applications that would require a client and a server to communicate over the network like Socket and Web API.

    I would really appreciate if you guys could help me out! Thanks in advance!

    Is this a well known comp sci problem?

    Posted: 05 Jan 2018 01:23 PM PST

    I'm trying to take a set of items and a "distance" between each item and find points on some coordinate system, say 2D or 3D, where the items could be placed to come close to the prescribed distances. There's no exact solution, but I want to minimize the error. I couldn't find anything on this. Has anyone encountered this problem before?
