I'm curious, what's DFD? Data Flow Diagram?

DFD Stands for Data Flow Diagram.
It is one kind of Graphical Representation of the flow of Data in Project.
For example my project is about Inventory Management System.
In My project there is :
Stock - inward
Stock - Outward
Customer
Suppliers
Bank
Order process
etc...
how to represent this using Data Flow Diagram. (dfd 1.0, 2.0...)
Please help me,
Thanks in advance.

And it sounds like a homework question. Ask your tutor or read a book. you never learn if someone else does it for you.

There is no real limit, it is all dependant on disk space and hardware performance. You may want to look at partitioned tables for performance. Also when you get to these volumes of data indexing is crucial.

I have several multi-selection options and its becoming a pain to handle them in a n-n fashion, does SQL2K5 offer an alternative that I might use?
I'll give you an example. I have a patient and a patient can have several symptoms.
This would be the exact opposite of sending an array to the database, it'll be bringing back an array.
|
|
|
|
|
So you have tables like the following?
Patient
- PatientId (PK)
- Name
Symptom
- SymptomId (PK)
- Description
PatientSymptom
- PatientId (FK)
- SymptomId (FK)
If so, what's the biggest pain in this?

That is exactly how it is only you would have a "versioning" of it for the patient. So that for each admittance (the one you helped me out with this morning ) the patient can and most likely will have different symptoms. I just find it painful that it has to go like this, it sorta like sawing against the grain. Implementation wise its not difficult and one can easily knock up a view to end up with a comma separated list of symptoms.
I don't know, I guess I'm just complaining.

Could you post any example what operation is painful or is it querying or something else? That would help to understand the problems and to give suggestions.
Based on our previous conversation I understood that you don't use surrogate keys (identity for example). If that's correct, perhaps the problems are related to that.

I'm just whining because I had little sleep last night. My baby son is teething.

I remember those nights. Luckily it was always one or two nights at a time with both of my kids. If it helps you in anyway, it goes over soon. And then again if you start counting the good sides and the bad sides of having children, there's no question which count is higher
I wish you strength and hopefully you get a good night sleep after this day. Perhaps we continue searching another data modeling solution for you another day

Yeah, he's a bundle of joy alright when the poor kid is not in pain.

I would like to rebuild the indexes of my database by using the query 'ALTER INDEX ALL'. With this I would like to set the option SORT_IN_TEMPDB to ON. But before that I want to know the value set for this particular flag in the table indexes. How can I get the current value of this flag?
I tried using the tables like sys.indexes, sys.stats, sys.schemas etc but miserably failed.
Please advice

AFAIK this information isn't stored when index is created or recreated.

Hi,
Then how do we know what is the value for this flag?
I want to set it on in our database now but I am not sure whether the people who created or maintained this database before were already set it or not?
Another doubt regarding setting this flag is that, will it cause any issues in the future w.r.t. Size or performance and w.r.t. Tempdb as well?
With Regards,
Abraham Chethuvelil
