A good trigger framework is:
- Scalable, due to built-in bulkification.
- Traceable, clearly showing what logic is executed, and when, for each record.
- Reusable, because functional methods and classes are clearly separated.
- Atomic, allowing you to bypass specific triggers when needed.

What is an Apex trigger?
A single Apex Trigger is all you need for one particular object. If you develop multiple Triggers for a single object, you have no way of controlling the order of execution if those Triggers can run in the same contexts. 2) Logic-less Triggers.

If you write methods in your Triggers, those can’t be exposed for test purposes. You also can’t expose logic to be re-used anywhere else in your org.
Why do you put logic in trigger handler?
By putting your logic in your trigger handler, instead of your trigger you allow yourself a much simpler path to testing your trigger . You don’t have to do tons of real inserts on the object to test the logic within the trigger, you could create mock objects and call the trigger handler class to test the logic in your trigger instead (test mocking is a wonderful thing that saves you tons of time, but we’re not covering that today).
What is triggerhandler class?
Basically what it’s doing is checking whether or not the trigger should run, and then running the method for the respective trigger context we’re currently in. Pretty simple, pretty kewl. That’s literally all it takes to leverage this framework for your own code.

What is trigger factory?
Trigger Factory is a patterns that provide an elegant way of coding triggers to avoid bad practices such as repetitive SOQL queries that can hit governor limits and multiple triggers over the same object. The patterns enforce a logical sequence to the trigger code and in turn help to keep code tidy and more maintainable. Keeping trigger logic for each object in a single place avoids problems where multiple triggers are in contention with each other and makes it easier to debug. Enforcing up front caching of data within a trigger keeps the trigger ‘bulkified’ and avoids those nasty ‘too many SOQL queries’.
How many triggers per object?
