In a recent forum message, Jay S wrote:

"Does anyone know why MS Access closes whenever you try to work in the VBA module? I tried reinstalling it but received the same error. I tried different operating systems, some it will work on but other times it will not.

The error message is that "Microsft Access needs to close".

If anyone can help that would be great!"

Recovery Models in SQL Server

2009-10-27T06:54:51Z

SQL Server provides three different recovery models that allow you to specify the way SQL Server manages log files and prepares your enterprise for a disaster. Each of these models represents a different approach to balancing the tradeoff between conserving disk space and providing for granular disaster recovery options. The three disaster recovery models supported by SQL Server are:

Full recovery model

Simple recovery model

Bulk-logged recovery model

Third Normal Form

2009-10-25T06:52:51Z

In a recent forum message, Wolfman wrote:

"We have a large form based application. The form has several sections which the user fills in and they have a vast amount of information on each section, around 150 items of char, numbers and text. These sections are always read/written as a block.

If I have a table- FormSection2Physical which contains 150 columns which describe each of the questions on the form is this a violation of normalization in any way?

We also have a doctor invoice:

id, doctor_id, location_id, diagnosis1, diagnosis2, diagnosis3, patient_charge, amount, location_different (boolean)

Are there any issues here?"
