I'm trying to normalize my database the best I can this time around and I'm
running into some trouble. I've been avoid normalizing for a long time now
because while I know how to normalize, I'm weak on SQL strings so populating
the database is a pain in the kee... but this is another story...
ok, first of all is this a many to many or no?
projMain (table)
projID (PK)
clientID (FK)
etc.........
ProjWebs (table)
webID (PK)
projID (FK)
stageID (FK) ***
SDLC (table)
stageID (PK) ***
stageName
stageDescr
*** is this a many to many relationship? Rather than hard coding SDLC info
I'm putting it into a table. Since many of the records in ProjWebs can
relate to many in SDLC and visa versa, this is many to many, yes? If so,
how can I create One to Many without make a seperate table for ALL SDLC
stages?

Thanks! 2 1405

The asterisked relationship is a one-to-many relationship. The entire
3-table structure is a many-to-many relationship between projMain and SDLC.
A many-to-many relationship consists of two one-to-many relationships
combined via a "bridge" table.

You can't. The only way to implement a many-to-many relationship is to use a
bridge table. From what you are saying, it sounds as if it's the right thing
to do. Don't shy away because it's a little work. :-)

oh man, my SQL chops are about to get spanked. I have no idea how I'm going
to write strings or procedures for all this, wow. Well, I'll be back with
more questions I guess ;-P
Any recommendations for a solid SQL instruction-guide book? I have to get
better chops. Been cruising Amazon and SQL in a Nutshell "second edition"
( I guess the first was just so-so) looked fairly complete concise. Anyone
agree/disagree? Looks like I'm going to have to become "Captian
Join-Master".
Thanks!

I'm trying to build a database that will handle the monthly billing needs of

No biggie, right? Well, here's my problem. I don't know how to tell access
to modify everyone's account balance each month. And I can't just always
assume that their monthly bill is $16 just because their balance is $16. If

Is there really any advantage to using DIV elements with float style
properies, vs. the old method of TABLE and TR and TD?
I'm finding that by using DIV, it still involves the same number of
elements in the HTML to get everything just right. When you consider
the class attribute on the DIV elements, there's not much size savings
anymore for using DIV.
There are other disadvantages to not using TABLE/TR/TD, such as the
lack of ability...

Hello,
Is it possible to create multiple foreign keys on a field in a table

For example, I have an Invoice table where the Customer field is
linked (foreign key) to the Customer table. As the application has
changed, I now want to introduce the concept of prospects by storing
them in a table dedicated to prospects only (no customers). I want...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
