    <p>Hope this helps. It describes the various types of factories. I used <a href="https://rads.stackoverflow.com/amzn/click/0596007124" rel="nofollow noreferrer">Head First Design Patterns</a> as my reference. I used <a href="http://yuml.me/" rel="nofollow noreferrer">yuml.me</a> to diagram.</p> <p><strong>Static Factory</strong></p> <p>Is a class with a Static Method to product various sub types of Product.</p> <p><img src="https://i.stack.imgur.com/5txhK.png" alt="Static Factory"></p> <p><strong>Simple Factory</strong></p> <p>Is a class that can produce various sub types of Product. (It is better than the Static Factory. When new types are added the base Product class does not need to be changed only the Simple Factory Class)</p> <p><img src="https://i.stack.imgur.com/O4mxc.png" alt="Simple Factoryt"></p> <p><strong>Factory Method</strong></p> <p>Contains one method to produce one type of product related to its type. (It is better than a Simple Factory because the type is deferred to a sub-class.)</p> <p><img src="https://i.stack.imgur.com/nyqGK.png" alt="Factory Method"></p> <p><strong>Abstract Factory</strong></p> <p>Produces a Family of Types that are related. It is noticeably different than a Factory Method as it has more than one method of types it produces. (This is complicated refer to next diagram for better real-life example).</p> <p><img src="https://i.stack.imgur.com/A6riH.png" alt="Abstract Factory"></p> <p><strong>Example From The .NET Framework</strong></p> <p>DbFactoriesProvider is a Simple Factory as it has no sub-types. The DbFactoryProvider is an abstract factory as it can create various related database objects such as connection and command objects.</p> <p><img src="https://i.stack.imgur.com/Qz6AK.png" alt="Abstract Factory From .NET Framework"> ​​​</p>

    1. COIs the difference between Static Factory and Simple Factory purely that the CreateProduct method sits within a different class?

    2. COWouldn't it be clearer if in the case of Factory Method, there was just `Product` ( as an abstract), and then `Product1` and `Product2`, as sons? That would help the point that Factory Method is just about creating one product, whereas Abstract Factory is more or less a bunch of Factory Method's gathered together in families.

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.
