    <p>I'm pretty exhausted trying to connect/link between practical issue to a theoretical equivalent .</p> <p>I will choose a very very simple example trying to illusrate my problem.</p> <p>Suppose I have a Worker class:</p> <pre><code>class Worker { private : // default access modifier int workerId; }; </code></pre> <p>Suppose I have a Table class:</p> <pre><code>class Table { private : // default access modifier int tableId; }; </code></pre> <p>Suppose I have a ResturantManager class:</p> <pre><code>class ResturantMangager private: // default access modifier list&lt;Table*&gt; allTables; list&lt;Worker*&gt; allWorkers; public: // the function should tell the worker that he should call one of its function, // its decision to what table to put the client returned by its function // must be somehow updated in the allTables (mark the table he chose to put the client // as unavailable). void putClientInTable(const Worker&amp; worker, const Client&amp; client); }; </code></pre> <p>Now I want to allow the worker to put a client in one of the available tables and after that I want the Resturant's class data member allTables to mark this table (by ID lookup) as unavailable. That means that the Worker should be able to decide what table to choose (or the ResturantManager tells him - I can't see how It can be achieved differently) and then the ResturantManager's allTables must be updated either.</p> <p>I'm looking a design pattern (<a href="http://sourcemaking.com/design_patterns" rel="nofollow">http://sourcemaking.com/design_patterns</a>) which most suitable to this idea.</p> <p>Is there any design pattern approriate to this issue?</p> <p>Thank you all.</p>

    1. COIf you already know what you need to do, why not just implement a solution?

    2. COI'm just not sure if there is a design pattern which sutiable to this idea and I can use it. It is always better than inventing the wheel again.

    3. CONone of the design patterns in the link you give (and those are the "usual" design patterns) are suitable on its own to solve your problem. And software engineering wouldn't be engineering if we didn't design new wheels every now and again ;)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
