+# @sapphirecode/modelling
+
+version: 1.1.x
+
+base classes for controlling data
+
+## Installation
+
+npm:
+
+> npm i --save @sapphirecode/modelling
+
+yarn:
+
+> yarn add @sapphirecode/modelling
+
+## Usage
+
+### Classes
+
+#### Persistent
+
+Persistent allows easy data transfer between classes that extend Persistent, as
+long as they have overlapping properties.
+
+to create a persistent type, create a class that extends Persistent and in the
+constructor, define all properties you want to store.
+
+Property types can be string, boolean, number or array
+
+```js
+import { Persistent } from '@sapphirecode/modelling';
+
+class Foo extends Persistent {
+  public constructor() {
+    super();
+    this.properties.foo = 'string';
+    this.properties.baz = 'boolean';
+  }
+}
+
+class Bar extends Persistent {
+  public constructor() {
+    super();
+    this.properties.bar = 'string';
+    this.properties.baz = 'boolean';
+  }
+}
+
+const f = new Foo();
+f.set('foo','bar');
+f.set('baz', true);
+
+const b = new Bar();
+b.assign(f); // f.assign_to(b) will do the same
+// now the property 'baz' of b will also be true
+console.log(b.serialize()); // Persistent also implements Serializable
+```
+
+Methods:
+
+- assign, assign_to, assign_object: (implementation of Assignable)
+- to_object: return data as plain object
+- serialize: return data as json string (Implementation of Serializable)
+- set(key, value): set property to a specific value
+- get(key): get a property
+
+#### DatabaseModel
+
+Extends Persistent and has the abstract methods read, write, delete and
+define_properties to allow working with databases
+
+in define_properties, set all the properties you need, id is automatically added
+and has to be a number.
+
+read, write and delete specify the actions needed to interact with the database
+itself
+
+#### ControlModel
+
+The ControlModel is there to verify incoming data and modify it if needed. It
+also extends Persistent.
+
+The method define_properties lets you define the data you will store.
+
+before_change allows you to register observers, that are able to cancel changes.
+the registered observers are called with the following parameters: (new_value,
+old_value, property_name). By returning false they can cancel the change that
+was about to happen.
+
+register_observer does the same thing, but those observers are not able to
+cancel the change and they are called after the change already happened.
+
+### Interfaces
+
+#### Assignable
+
+Base interface of Persistent
+
+Methods:
+
+- assign(b): assign data of another assingable object (b)
+- assign_to(b): assing data to b
+- assign_object(obj): assign data of plain object obj
+
+#### Serializable
+
+Interface to allow serialization of different data structures
+
+Methods:
+
+- serialize: serialize into a string
