I have a database table of plants, one of chemicals, one of products, one of illnesses. Each table is connected, for example lets say opium poppies. They contain the chemical morphine. Morphine is used in painkiller products. Its used to treat pain and other illnesses. On the opium poppy page, I want to list all the chemicals found in the poppy. All the products (i.e. opium, laudanum) made from the poppy. All the illnesses which are treated with the poppy. Users need to be able to edit this page, and enter chemicals, products or illnesses that are related to this plant. They also need to be able to edit the info on the page.
Making database relations is a pain in the ass with CakePHP. I don't want to waste any more time so I'm thinking maybe making it as a wordpress plugin is the way to go. How would you go about this? Is there an easier way than wordpress, like a better CMS, or framework? If I use wordpress, should I do all the DB interactions with AJAX to avoid having to interact with the DB through wordpress (this gave me massive trouble in the past since I had my data in an external db)?
