From MS Access One-to-Many Form to Oracle Express

Question

Hello, hello,
Firstly, I am new at Oracle and interested to really getting into out, however, I am a little ancy to get going. I'm looking for some sharp direction that could direct me to exactly what I need to do right now and then I can do further study, etc.
I have a MS Access database with many tables, queries, etc. But I set up a fancy form whereby I could scroll to the name (let's say EMPLOYEE) and then I have about 10 different forms (a tabbed interface because there were so many) show up where I could input data about that employee specifically. Then when I scroll to the next person, all of the subforms would change accordingly.
Thus, ultimately, what I would like to do using Oracle Express and APEX is to set up a page where I have a region which will pull a list of employees and act as a menu, then when someone select an employee (i.e., not only me) then all information, from numerous different tables pulls up and is visible, editable and can be added to. There could be a region for addresses, a region for links, for notes, for photos, for a list of articles, or whatever.
I hope you track with what I am looking at. In Access I have numerous tables, then I create a monstrous one-many relationship thingamajiggy and ka-boom, things all fit together in a form, and subforms. All editable by me, but hardly available for anyone else. I know Oracle is the way to go, so...
Can you assist me by explaining what I need to implement in Oracle? I am not clear on JOINs and what's the right one to use, how to adequately connect all of the dots, etc. Do I need to set up fancy queries, create SQL statements or what?
Thanks.

Answer 1

Thanks. I don't think my question is strictly APEX related.
Rather, I am trying to determine how to create a "one-to-many" relationship (to use MS Access terminology) in Oracle Express. And then solve how to add data to them.
I can create a view which links two tables together where I can add data, but I want to be able to be adding data to several tables all linked together from the same primary key. One row per person (or employee) won't handle this, particularly if you want to add more than one row of data about the person in a table.
For example, if I had a restaurant with four employees (a cook, a waitress, a baker and a cleaner), my employees table would only have four rows. But now if I wanted to record the types of desserts the baker could make, that would take up more than one row. Therefore, from the baker, it would have to link to another table where I could input data about the different desserts. Typical one-to-many relationship. But the baker can also make different kinds of bread, thus another table with several rows. Perhaps the baker is so good, I may want to have yet another table for his different supremely delicious and famous pies (apple, pumpkin, pecan, etc.) which is now another table. The options are endless, but they all connect to the baker.
As a result, someone could come to my application and ask what can the baker do, and it will pull up a table of desserts, a table of pies and a table of breads.
Once I figure that out and can link many tables together using one primary key, then I presume I can easily move into the web application aspect. But for now, I am not quite there yet.
If someone can at least direct me as to what this is called in Oracle and give me a little direction, then I will feel more confident in moving forward. Thanks again!
