Access Relationship Seminar
By Richard Rost   Richard Rost on Facebook Richard Rost on Twitter Richard Rost on LinkedIn Email Richard Rost   6/20/2012 1:34:26 AM

In this seminar, you will learn just about everything there is to know about relationships in Microsoft Access. Setting up proper relationships between your tables is absolutely crucial to building a successful database. Bad table design, and bad relationships between those tables, is disasterous, and will cause you nothing but trouble down the line.

This seminar covers just about all of the different possible relationship scenarios that you will ever come across. We will build eight (8) different database projects so you can see how to set up good relationships between your tables. This seminar will teach you about all of the following types of relationships:

1. No relationships
2. One-to-Many
3. One-to-One
4. Many-to-Many
5. Self-Join One-to-Many
6. Self-Join Many-to-Many
7. Reverse Relationships
8. Multiple Relationships

We will build sample databases to track:

1. Children to Parents with their relation (one-to-many)
2. Which parents receive mail on their child's behalf
3. Student data with a secondary optional detail table (one-to-one)
4. Vendors to Products and vice versa (many-to-many)
5. Employees to Supervisors (self-join, one-to-many)
6. Complete family history with relationships (self-join, many-to-many)
7. Organizations to Members (whether companies, families, charities, etc.)

Client Projects with Employees Link 
Norma Killian    
If I have a client that has multiple projects and each project can have multiple employees with different roles and status how would that be setup if I assign the original project and need to populate the information on one form and the employee(s) complete their portion on another form?

I was starting to normalize my tables and think about the relationships among them. I have a Node table and a DesignStatus (DS) table that I know is a one to many from the DS table to the Node table but am wondering, just out of curiosity, if it is a one to one from the Node table to the DS table.

One other question please: When creating the combo box for the MemberID in the subform - it was based on the Member query and I noticed the dialog box that helps you add the combo box asked 'Choose a field that uniquely IDs the row. Which column in your combo box contains the value you want to store or use in your database?' Then the next screen asks, 'When you select a value in your combo box, what do you want MS Access to do?' And you chose, 'Store that value in this field: Member ID'. Aren't those 2 questions asking the same thing? If not, can you describe in detail what the difference is? Sorry. Thank you, again!

Lesson 16 Review Link 
Kris Cunningham 
. In the beginning of the Lesson 16 Review you said, to mention if you would like to see a seminar on how to fix a flat file and build relationships. I would like to see it, especially how you normalize various examples of tables. And would like to see even a mini seminar or however long it would take with more examples of normalization other than what you showed in an earlier lesson. I m having trouble translating the examples I see with how to normalize my data, which pertains to the telecommunications industry. I'll add this suggestion to the survey. Thank you! Read More...
