CakePHP 2.x: working with an existing database that does not follow the naming conventions

Question

I am new to CakePHP 2.x. What would be the best solution for working with an existing database that does not follow the naming conventions?

My current task requirements:

1. Existing database contains a lot of tables (more than 20)
2. My task requires read and save operations.
3. The solution makes maintenance more manageable in the future.
