    <p>In a statically typed language, such as C++ or Java for example, <code>static</code> may refer to the information known at compilation time while <code>dynamic</code> refers to the information known at runtime.</p> <p>For example:</p> <pre><code>struct Base { virtual std::string name() const { return "Base"; } }; struct Derived: Base { std::string name() const { return "Derived"; } }; void print(Base const&amp; b) { std::cout &lt;&lt; b.name() &lt;&lt; "\n"; } </code></pre> <p>In the <code>print</code> method, the <code>static</code> type of <code>b</code> is <code>Base const&amp;</code>. Therefore, the compiler will check that all methods called exist in the context of a <code>Base</code> object.</p> <p>However, when execution comes, the call to <code>name</code>, as the method is virtual, is performed with regard to the <code>dynamic</code> type of the object:</p> <ul> <li>this may be <code>Base</code></li> <li>this may be <code>Derived</code></li> <li>this may be another derived class from <code>Base</code> that we know not yet</li> </ul> <p>Therefore, in the following example:</p> <pre><code>int main(int argc, char* argv[]) { if (argc == 1) { Base base; print(); } else { Derived derived; print(derived); } }; </code></pre> <ul> <li>The <code>static</code> and <code>dynamic</code> type of <code>base</code> is <code>Base</code> and <code>derived</code> is <code>Derived</code>.</li> <li>In the <code>print</code> method, the <code>static</code> type of <code>b</code> is <code>Base</code> (always)</li> <li>Depending on the number of arguments, the <code>dynamic</code> of <code>b</code> is either <code>Base</code> or <code>Derived</code></li> </ul> <p>It is a current mistake to assume that polymorphism is necessarily based on dynamic memory allocation, but the two concepts, while not orthogonal, can be used without one another in some conditions.</p>

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.
