WOW! This is the BEST explanation of the "SO WHAT" for Access. I've been having a difficult time trying to figure out the Relational aspect, particularly in regards to the "Normalization" of the database. This is FANTASTIC.
I agree. Your videos are a fantastic resource for those of us who are just starting out. Thank you very much for taking the time out of your day to put these together!
I've been watching this video to understand access database better for my class. Now I'm giving my exam on it. Thanks to you, I feel more confident about it!
Thanks so much for the succient yet clear explanation, i want to study the Northwind database, and checked the link, but it does not work, i could not download the file. can you please kindly share the file with me? 🥰
Thanks! This web page tells you how to download the Northwind database through the templates feature. learn.microsoft.com/en-us/dotnet/framework/data/adonet/sql/linq/downloading-sample-databases
Amazing video. However, I have a question... How is the ShipperID (primary) key in Shippers table linked to a ShipVia as a 1 to many relationship in the Orders Table, when the ShipID and ShipVia names do not match? I thought they always had to match like SupplierID (primary) in Supplies Table to SupplierID (many) in Products Table. What am I missing? LOL
Very observant! The fields used in a one-to-many relationship do not have to have the same field name as you pointed out. It is common to give them the same name, but not technically required.
I'm stuck with sub datasheet view! for example, I've 3 separate tables. wanna relate them with one junction table. say, number 2 table has a common field ( could be described as the master field ), which is related to two other fields. one from number 1 table and another from number 3 table. after creating the relationship, when u press the " + " sign of the sub datasheet view, " insert sub datasheet " dialogue box appears! why so? I just wanna see related fields to that particular field. why that doesn't happen?
Subdatasheets show the "many" records related to "one" record in the table you are viewing in Table Datasheet View. So only the table on the "one" side of the relationship will have the ability to show a subdatasheet.
If you're getting the "Insert Subdatasheet" dialog box it means that you're viewing a table on the "one" side of a "one-to-many" relationship to more than one other table...so you have to choose which table's records to view in the subdatasheet.
I thought the middle link table was the 1-side of the other two connecting tables. Creating effectively two joined many:1 tables that make up a many to many relationship.. ?
No. If two tables have a many-to-many relationship then you model that with a junction table that is on the MANY side of a 1-to-many relationship with the two original tables in a many-to-many relationship. Go to the 4:12 minute mark in this RUclips to see how many-to-many relationships are resolved with a junction table. Products and Orders have a many-to-many relationship that is resolved with the Order Details table. One product can be ordered many times and one order can have many products. Note that the Order Details table is on the MANY side of the relationship to both Products and Orders. Another example is the Customers and Shippers tables. They too have a many-to-many relationship that is resolved with their one-to-many relationships to the common Orders table.
i need help, i have item say tshirt size small, but the price varies with different customer. say customer A, the tshirt small is US2.0, IF customer B the price its US 3.0, and tshirt medium for customer A is US4.0 AND US5.0 FOR CUSTOMER B. how do i make the table for this scenario
You'll need a Sales table with a field for the actual price per sale. Customers table has a one-to-many with Sales. Inventory table has a one-to-many with Sales. And you can even have a suggested/regular sales price field in the Inventory table. But the Sales table must have a field to record the actual price given you're telling me that the price may be different for each sale.

Great to hear!
This was very well explained, thank you.
This has helped me understand the depth of thought needed when planning out a db before you even start!
Lisa you are making me better at my job and I appreciate you!!!
Thank you! See all of my RUclipss organized at learncs.w3spaces.com
Great video! It explained relationships clearly and concisely with great examples that answered the question I had. Thank you!
You're very welcome!
Another excellent video: I’m glad That RUclips found you for me!!
Tysm. See all of my RUclipss organized at learncs.w3spaces.com
We are looking forward for more on Acces from you, Especially explain the making of Northwind
I just started a new playlist based on the northwind database!
