my collegue want to use the traditional method of creating tables manually and doing everything manual, till now i try to convince him to use modern technologies, i even showed him this forum and your replies about the advantages of using modern technologies, he told me these guys have more experience, but we in our situation we are considered beginners and we should know all details of our projects in order to learn and understand staff in details
It seems to me that you have a good understanding of the data that will go into your system, if you already know how the database will be structured and all that. What your colleague is wanting to do is spend time writing and debugging code that handles the CRUD (create,read,update,delete) functions.
My question for him, is "Why would you want to re-invent the wheel?"

now i only need to learn well about one good ORM in order to be able to convince him, currently i'm studying doctrine2 and laravel, if i understand them well and after testing them in my test project, that time i can demonstrate to him how to use it and the benefits we can get behind using it,

That's exactly what so many newbies say.... "Well, these people have experience and know what we need, but we'll do something else because we are sure that the fact that we don't know means that we know better than those that do know."
It's insane. It's the same logic that people going to college often use - instead of getting advice from people successful in their field, they go to people who can't work in that field or have failed at it and get advice from them because it is often "feel good" advice instead of useful advice. It makes no sense.
Our advice is based on the level of knowledge and experience that you have. His logic indicates that he should not be allowed to be in a role of decision making at all, it's a horribly dangerous thought process. He knows when good advice has been given and intentionally does something bad just to fail.

Apparently, for it's own sake.

No, you should NOT need to find a good ORM. That's what we are saying.
-
What you need to do is...
- Figure out if you need relational data at all. We aren't even up to the point of talking frameworks yet.
- Only look for frameworks, talking ORM means you've already missed the modern development boat, here.
-
our first model is the following, after that we gonna add more entity by the time
by the way it is only the payroll model of our application
-
as far as i can see, the modern way is not to begin with modeling, isn't it??
-
@IT-ADMIN honestly, that doesn't look like it should be relational at all. This is a prime candidate for not being relational. Who suggested relational?

No, the modern way is not to model it at all. The framework models it for you.
-
If you do your own modelling and them try to use an ORM, that causes a ton of extra work, defeats much of the purpose of the modern systems and can easily introduce performance problems.

why it should not be a relational DB, ??
-
all entities are related to each other,

Because relational is not the default choice. Relational is heavy weight and slow. Extra effort, extra problems. If you don't need it, it's not good for you.
Nothing in the data that you has leverages a relational system really. It's perfect as a document.

@IT-ADMIN said:

Yes, of course, but not in a way that suggests that a relational database is valuable. You have modelled the data correctly to use a relational database for it, but a relational database is incredibly inefficient here and unnecessarily strict. You aren't getting any benefits from the relationships. And as another thread covered... all data is relational. By the "rules of relationships" every CSV is relational data. That the data is "relational" is meaningless. It's that it is not useful in a relational database that matters. All databases have relationships.

lol, you can't be serious, how we can know a specific card to whom it belong,
i'm really in a state of lose, -

i'm really in a state of lose,Card meaning, like passport? Well it depends what you use. But if you use a document database like MongoDB, you would either know that it was theirs because it would be contained within their document. Or you would have a key that associates them.
You are confusing the idea of data that relates to other data and the usefulness of a relational database. They are rather different things.
-
the project is under construction, the entities will be added to this model by the time
-
Look at the post that you just wrote. The post is associated with you, right? The post and you have a relationship. Yet MangoLassi has no relational database. So clearly relationships in data are not lost by not using a relational database. You don't choose a relational database model because your data has relationships. Remember most systems should not be relational, but all data has relationships.

But just like the passport, you would just add them in the user's document. Your data is really ideal for a document database.
