I don't think it does.
It's pretty do-able to design a database in Filemaker yourself, but that ofcourse depends on your ability to learn a new program and the complexity of your database.
I have made several tutorial video's to help people learn to work with filemaker.
You can find them on my youtube channel.
You might want to start with this one:
You could watch it to see if this seems like something you could do or not.
I would always advise starting your own database from scratch. That way you know exactly what's going on under the hood.
Thanks for the link and your thoughts on this matter.
You can also review the starter solutions that come with FileMaker. While none are labeled for truck maintenance, one or the other might be adaptable and they can provide examples of how you might implement certain features that you want with your database.
If you are trying to decide whether to purchase this product, download the 30 day free trial, it will come with these starter solutions.
