best way to store questionnaire data in a database.Since different questionnairs have different questions and formats i.e dropdown, radio, checkboxes etc building such a database model becomes highly complex.
I've read that if data schema is complex and higly variable it may be better to use an xml document and store that in a databse. However I dont quite understand how you store xml to a database. Do you simply store the entire structure in something like a nvarchar column or is there some other way to store xml to a database.
If you store the entire structure to the databse then how do you query the content to generate reports.
Hello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?
I have a system that basically stores a database within a database (I'msure lots have you have done this before in some form or another).At the end of the day, I'm storing the actual data generically in acolumn of type nvarchar(4000), but I want to add support for unlimitedtext. I want to do this in a smart fashion. Right now I am leaningtowards putting 2 nullable Value fields:ValueLong ntext nullableValueShort nvarchar(4000) nullableand dynamically storing the info in one or the other depending on thesize. ASP.NET does this exact very thing in it's Session State model;look at the ASPStateTempSessions table. This table has both aSessionItemShort of type varbinary (7000) and a SessionItemLong of typeImage.My question is, is it better to user varbinary (7000) and Image? I'mthinking maybe I should go down this path, simply because ASP.NET does,but I don't really know why. Does anyone know what would be the benifitof using varbinary and Image datatypes? If it's just to allow saving ofbinary data, then I don't really need that right now (and I don't thinkASP.NET does either). Are there any other reasons?thanks,dave
I have a bit of a dilema, that maybe someone can give a reccomendation on. I have a vb app that will calculate a duration that a process runs in hours:minutes:seconds. My question is should I store this in the database as a date/time field or calculate total seconds and store it as an integer field? I will be using this field for basic summing calculations in the future. Thanks for any help.

hello ... i have a project this semester and i had to study is storing images in a database ( using Microsoft Access ) is good or bad ? so any one could tell me the advantages and the disadvantages please ... thanks bye
An odd question from me, I know, but this time, I assure you a twist.
I have a group that wants to store images in either a database or a file share, in order to make a certain website able to run on a load balanced web farm. These images are around 1KB each in size, and have a lifespan of exactly one use (think of graphs). I went a-googling, and found no shortage of articles that say "don't do it, but here's how you can do it", but I did not find any real hard statements as to why to not do it. Needless to say, this is hurting the case for not putting these images in the database. I have found an article that says images over 8KB will have worse performance, but I can not use that factoid here. For the moment, I have the developers leaning toward the fileshare, because they will be writing transaction logs all day, which will be more work than the fileshare needs to do....I think. The best I can do, is cut the text/image datatype overhead, and have them create the table as varbinary(2000), but even then, I don't like the look of the idea.
Anyone out there have good articles/whitepapers that detail the differences between writing single-use images to a fileshare vs. a SQL database? <baiting=blatant>Failing that, do any of the Microsoft development team have an opinion?</baiting>
Alternatively, what is the general opinion of keeping session state information in a database (because I bet that will be my next battle). I see .NET includes a session state server, but not being a programmer, I can not create an opbjective test.

Hi,I have a table which I need to store times in. What is the best way of doing this? The only way I can think of so far is to save the times as a datetime such as '1/1/1900 03:00 PM' then format the date as "hh:mm tt" so that the day isn't displayed. Is this the best method?Thanks,Curt.
I have records with 50 plus fields of data.I was thinking of writing all the fields data into a XML file and then store it in a SQL server database for retrieval later on.Is there anyway i can go about doing this?
Just a quick question to ask what is the best field to store the data held in a rich text box/control. Just want to make sure that i get it right first time you know. Not sure about the amount of characters that needs held but its going to be quite a lot as this field shall contain most of my pages content.

What is the best approach for storing hierarchical data in a database? For example, if I need to store a tree menu system, how would I do that allowing for the most normalization within the database, using the least number of queries/resources when pulling the data out, and using the least amount of overhead both in storage and retrival?

Hi There,Being quite new to MS-SQL I would like to ask if there is a general opinionof what approach should be taken to storing things like external documentsand images in databases.Should the actual files be stored within the database, or instead shouldlinks to the files on a file server or something similar be stored instead.For the end user I imagine it is easier to have everything stored within thedatabase, because doing it the other way in effect gives another level ofmanagement because there is the need to perhaps manually look after the fileserver with all the image files or document files on.In my particular case, I am building a database where the users use a greatmany Word documents. For example, I particular record might have a number ofdifferent Word documents associated with it.I was going to create a "Documents" table that all documents were stored in(including meta data about each document because it will be really useful tobe able to search for documents so that they can be reused).In this table I was in a dilemma as to whether to actually store thedocuments in the table. Other then the performance hit and memoryrequirements this will require, are there any other disadvantages?What are the general thoughts when a database needs to manage a lot of pdfand word documents?Thanks in advance.Dave.

Dear all I create this html file on the fly in my asp.net application abd what i would like to do is to store it inside my sql2005 database. What would be the best way?The html file itself is not really big. Probably not more then 600 - 800 characters most. I was thinking the text type fields of the database and then when retreiving it dump it inside in a file and save the file with html extention. Are there any better sugestions? Thank you for your time
I am contemplating storing session state data in a SQL server database (created by running the installSqlState.sql script included in the .NET framework installation) and have established a functioning connection to the database but I am constantly getting "access denied". I've found that tweeking the permission settings in SQL for the ASP.NET user is resolving each specific error that arises but was wondering if there is a more "global" resolution? I'm finding myself having to manually check off each individual object and every option or is this what is needed to resolve the "access denied" error?
