    <p>I have a class which defines a historical extraction on a database:</p> <pre><code>class ExtractionConfiguration { string ExtractionName; time ExtractionStartTime; time ExtractionEndTime; // Should these functions be static/non-static? // The load/save path is a function of ExtractionName void SaveConfigruation(); void LoadConfiguration(); } </code></pre> <p>These ExtractionConfigurations need to be saved to/loaded from disk. What is the best way of organising the save/load functions in terms of static/non-static? To me, it is clear that SaveConfiguration() should be a member function. However with LoadConfiguration(), does it make more sense to call</p> <pre><code>ExtractionConfiguration newExtraction; newExtraction.LoadConfiguration(); </code></pre> <p>and have a temporary empty instance or make the load function static</p> <pre><code>static ExtractionConfiguration LoadConfiguration(string filename); </code></pre> <p>and just call</p> <pre><code>ExtractionConfiguration newExtraction = ExtractionConfiguration::LoadConfiguration(filename); </code></pre> <p>which feels neater to me, but breaks the 'symmetry' of the load/save mechanism (is this even a meaningful/worthwhile consideration?).</p> <p>I suppose asking for the 'best' answer is somewhat naive. I am really trying to get a better understanding of the issues involved here.</p> <p>P.S. This is my first question on SO, so if I have not presented it correctly, please let me know and I will try and make the problem clearer.</p>

    1. COWelcome. To format as code, you indent the section of code by 4 spaces or 1 tab. See http://stackoverflow.com/editing-help.

    2. COThanks Kenny, I was *sure* I was missing a trick with the formatting there!

    3. COYou should use shorter names. E.g. just save and load, since they are already inside the class. Not everybody uses Intellisense :)

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.
