DataSource Controls :: Database Design Tip Required?
Jun 4, 2010
I am building a page that displays a product's details, with the information being called from an MSSQL database.I would like to be able to have a variable number of features listed for each product, so for example, Product A has a list of 3 features, Product B has a list of 7 features, Product C has 2 features listed etc.I would like to avoid having a lot of NULLS in my database, and would prefer not to restrict the number of possible features listed.Is there a common way to tackle this problem? Is it simply a case of setting up a table just to store features?

everytime I modify an SQLdatasource using VS wizards, I have to dettach the mdf in VS's server exporer, then hit refresh in the browser, then get the applicaiton is offline error message please remove some pia file, but i usually just count to 12 and then hit refresh again and the page renders properlyhad scoured the forum on more than one ocasstiion, think it has something to do with the Admin rights within SQL, Ive tried the SQL server surface configuration tool, and add administrator stuff, but not sure if i should add (user to provision) something like the asp.net thing, or network services or ??also cant figure out where to view which administrators are actually on SQL server,

In general terms, which way will require more server processing power and which way will return faster queries... if there is even a difference. The client's database is still on the dev MS SQL server but is essentially but the client has decided they want to collect two more fields of information. Both fields are going to be collection text data and probably varchar(300) will be sufficient for the column data types. Would it ultimately be more efficient to
Add two additional columns in the main table so the data is entered directly into each record, or Add an additional table (or two) with a foriegn key to the primary table that holds the info for each new field The SELECT statement for the main table could be modified to either add the new columns (a.NewColumn1 and a.NewColumn2) or it could contain nested SELECT statements that pull in the data from the other tables. Custom daisy-chained Insert or Update statements would be no problem and a cascade Delete relationship would take care of any deletions. I'm just trying to figure out which would be better from a performance standpoint?

Not sure if this is for SQL or .net! I have 3 tables which looks like
table1
ID Name
1 Jon
and
table2
ID Number Job
1 1 IT
2 1 Web
3 1 Admin
table1
ID ContractType
1 Temp
1 Perm
An inner join makes one table with 3 rows (I excluding the ID from table 2 for the join) which is saved as a view
viewTable
ID Name Number Job ContractType
1 Jon 1 IT Temp
2 Jon 1 Web Temp
3 Jon 1 Admin Temp
4 Jon 1 IT Perm
5 Jon 1 Web Perm
6 Jon 1 Admin Perm
I want to display these results on a web page via the grid view. However, I don't want to show the user 6 times! I want to show the user name once, the contract type once and each Job! What is the best way to do this? Is there a fault with the database design already? I assume the easiest answer is to not join them in a view but query each section 3 times from the website but I'd rather 1 connection only!

I am writing an app that has a bit of process flow to it. On the save of a record, I need to check some fields to make sure they are not null. If they are not null, I will update a 'SectionComplete' field to true.
The thing is, I would like to store my fields in the web.config. So, I would like to have a string in the appsettings section that has a list of field names that are required. Then in my method, I would call these fields out and check each one for the specific record id, and then update the database.
I would like to do this in the web.config so we could add/remove columns without having to redeploy.
For example: my required fields are name, id, and phone. For section one to be labeled complete, all of these fields would need to be not null.
web.config would have this entry:
<add key="Stage1Fields" value="name, id, phone"/>

I used the Database Publishing Wizard to create a copy of my live SQL Server database for testing purposes. Both the live and test databases are hosted by my ISP.
What is the easiest way to transfer design changes from one database to the other without altering the data (assuming that the design changes are compatible with the existing data in the target database)?
Any proposed solution would have to be available via Visual Web Developer 2008 Express or SQL Server 2008 Development Edition.

I have the attached database design.
The database has been designed for a tradesman web site, i.e. Plumbers, Builders etc. The two main tables are tblCustomer and tblTrader which will stored data from two frontend web pages where the customer and trader can enter their personal details. After a customer enters their personal details (i.e. registers through the site) they will then be directed to a child page where they can progress to entering a specific job attached to a specific trade (i.e. Plumber) and trade type (i.e. Bathroom Installation), once a customer job has been entered I want these details to be emailed to all the trader_email addresses from tblTrader, from this email alert the traders will then enter the system and offer quotes to the customer through tblTraderQuote where the customer will then accept the best quote for them.
What I also want to implement is some sort of rating option that will allow the customer to rate their trader, either something like ebay's feedback or just a simple 1-5 rating option? How can I implement this into my database design or is this something that should be performed within the programming layer?

design pattern that works well with Visual Studio data tools against an MS SQL server; to retrieve a subset of an object's fields for all rows, and then on-demand retrieve the remainder for one row. I.E. just the small summary fields that I will serialize to a master grid view, then the larger properties including a large blob that I will render in a detail view. The performance hit from retrieving the large blob with the master result list would be too great.
The data shape is static, and I can define two separate data classes to match the specific summary vs. detail information returned. However that sounds anti-pattern-ish, to define the data classes specifically to suit the presentation layer. It also presents another problem, how to translate from the summary item to the detail item in an object-oriented way?

I was assigned a task on creating a web application that connects and display database information on a grid view. My supervisor suggested me to download .NET pet shop 4.0 to serve as a template for my project.As I only have limited basic knowledge on C# and HTML codings, the .NET pet shop 4.0 is too difficult and complex for me to understand. So I have a few questions:
Which functions are required to connect to the database? Which functions display information of the database? How do I change the categories of the .NET pet shop 4.0? If I want to add a grid view to display the records instead of listing informations of the products, where should I add the code and how will it roughly look like?

I'm trying to figure out if it's possible to transfer records from SQL central database (who has a public IP address) into SQL local database (who doesn't have a public IP)?
or if it's not possible can I use a centralized website instead to pass some data into the local website? (but i'm not sure if it will have some security concerns)..

Creating a system with web front end and SQL backend (microsoft obviously). I have tried using the asp.netsqlprovider but i can;t as i am only allowed one database on the server, so i then tried to update my current database with the triggers to input the schema into the already existing database.Next step i create my own table with two simple fields of username and password and try and authenticate that way, i can't get that to work either.
I ahve limited permissions on the network as i am a University Student. I really don't know what to do. Never had to create a log on system before and i thought it would be far simpler than this. I ahve used Microsoft's sqlprovider schema before and it worked fine. I have also authenticated via IIS and AD too before. I can't do any of those two in this instance it seems.I need an alternative for logging in users, if needs be in can be crude. I also still need to have some kind of two different views too for logged in users and not logged in users, but that can change if needs must.Don't let me down people, haha. Think this posts in the correct place, i could not find another one i thought could be more relevant.

I have a development database and one in production. There are two different sets of data in each database. On my dev system, I have mostly dummy data that I test with and in production is the real data for my web application. I recently added a new feature to the app that required a new table, and a new field for a foreign key in an existing table. I now need to upload that new structure to the production database without overwriting the live data with my test data.
If I run the Database Publishing Wizard, and choose "Schema Only" will it import the new structure and leave the existing data alone, or will it drop the records in my production database tables?
