-====== Natural Class ====== +Here’s the truth, living in London means you’ve had to work around awkward spaces. From wonky walls in old terraces to tiny kitchens with no counter space, London homes don’t exactly make life easy. That’s where [[http://www.koha-community.cz/mediawiki/index.php?title=U%C5%BEivatel:Latosha4915|custom joinery London]]-built furniture comes in. And no, you don’t have to be loaded to get something bespoke. Bespoke is for anyone—especially if you’re tired of living with wobbly, badly-fitted bits. No two flats or houses in this city are alike. So why would you settle for something made for someone else’s space?
-===== Meaning 1 =====+
  
-==== Alternative Terms ==== +I once helped a family in Walthamstow who had this tiny dining space under the stairs. No shop-bought table would fit—trust me,  bespoke furniture London store they tried. So we had a bench seat built into the wall, and suddenly the room worked perfectly. That’s the kind of difference a custom piece can make. Another client in Islington had an awkward loft bedroom with a sloping ceiling. Standard wardrobes didn’t fit. We worked with a local joiner to create a built-in unit that used every inch.

-==== Definition ==== +
-A **natural class** is a class which was not artificially created as part of the solution but derived from the problem domain of the software. +
- +
- +
-==== Description ==== +
- +
-Someone with no technical knowledge but knowledge about the application domain can come up with natural classes as they are just concepts and abstractions derived from the problem domain. Software typically also requires some [[artificial class|artificial classes]] for its solution but the [[principles:Model Principle]] tells to avoid them in favor of natural classes if there is no greater benefit from introducing an artificial class. According to [[principles:Model Principle|MP]] and [[principles:Tell don't Ask/Information Expert|TdA/IE]] functionality is mapped to natural classes and artificial ones are only created for special purposes. Often [[patterns]] make creating artificial classes necessary, although this is not always the case. +
- +
-Note that natural classes and [[domain class|domain classes]] are related but not the same notions. Each domain class is a natural class but not the other way around. A domain class is a class which is part of a [[patterns:domain model]] (typically stored in a database, etc.) whereas a natural class is just one which is not artificially created. Even classes like ''DatabaseConnection'' or ''HttpRequest'' are natural classes, because they represent a natural concept which exists independent of the software. Classes like ''BeanFactory'' or ''InvocationHandler'' on the other hand are not meaningful outside the context of the software, of the solution. So these are artificial classes. +
- +
-==== Examples ==== +
- +
-  * Classes like ''Book'', ''User'', ''Contract'', ''Order'', ''OrderItem'', etc. are natural classes and also domain classes. +
-  * Classes like ''Button'', ''TextField'', ''DatabaseConnection'', ''HttpRequest'', ''Time'', ''Integer'', ''Velocity'', ''Voltage'', etc. are also natural classes but typically not domain classes. +
-  * Classes like ''ActionListener'', ''ConnectionAdapter'', ''BeanFactory'', ''InvocationHandler'', etc. are //not// natural but artificial classes. +
- +
-==== Alternative Definitions ==== +
-/*i.e. slightly different definitions for basically the same thing*/ +

 +Now it looks sleek and smart. When you go bespoke, you also get a say in the design details. Want solid oak? You’ve got it. Hate chrome legs? You can skip all that. It’s your furniture,  handmade bespoke furniture London your way. I’m not saying everything has to be custom. There’s a time and place for IKEA. But for the stuff you use daily, custom is just better.
