Hi,
I would appreciate any help or suggesions on starting with database design for an asp.net site.
I know this question maybe sounds silly but I feel stuck and don't know where to start.
Yours sincerely

How to design tables in SQL Server for the above.
When our rep distribution services time-out (several times a day) some dba's just restart the service while others restart the rep job which starts the service. Are there any differences between these two methods? Does restarting the service inherit any changes made to the job's attributes?
Thanks!
OK, I've been looking and maybe there is an answer to this somewhere, but I haven't seen it.
I've got a database that has as its status "Shutdown, Normal". All the other DBs on my machine are "Normal" as status. The problem is that the one that is shutdown is the one I really need to be executing in. How do I start it?
Thanks!

Hi,
I have a SQL2k STD with SP3 installed.
Currently, only one database db_XYZ is there. The server has been started up since 07/03/2003 16:00 pm. But in the sql server current log: "Starting up database 'db_XYZ'." info is spreading from that time (16:00 pm) to this morning 10:00am at an interval from every 1 minute to 4 minutes.
Why need to 'Starting up' this database so much times?
This reminds me that this 'Starting up' is kind of 'abused' in many other servers. Any idea?
thanks

OK, I am experienced in VB6 but new to SQL.
And I want to use SQL for my database for some software I develop.
I have understood the basic principles how to communicate with a data base using SQL. What I have not understood is how I start a new database for SQL, subject SQL as such is installed on the server. But how to initiate a new data base?
Will really appreciate help with this.

Ok, I'm doing a football database for fixtures and stuff. The problem I am having is that in a fixture, there is both a home, and an away team. The tables as a result are something like this:
-------
Fixture
-------
fix_id
fix_date
fix_played
----
Team
----
tem_id
tem_name
-----------
TeamFixture
-----------
fix_id
tem_id
homeorawayteam
goals
It's not exactly like that, but you get the point. The question is, can I do a fixture query which results in one record per fixture, showing both teams details. The first in a hometeam field and the second in an away team field.
Fixture contains the details about the fixture like date and fixture id and has it been played
Team contains team info like team id, name, associated graphic
TeamFixture is the table which links the fixture to it's home and away team.
TeamFixture exists to prevent a many to many type relationship.
Make sense? Sorry if this turns out to be really easy, just can't get my head around it at the mo!
Hi,
I've got a sitatuation where one of our sql databases appears to be frequently "starting". The log entry looks like:
Starting up database 'Database'.
And seems to occur at irregular intervals and does not seem to be inline with any other db activity....i.e. transaction log backups, insertions or reads.
This DB is fairly busy receving inserts from our PBX CTI software almost constantly.
Note this is the only DB on the server displaying this behaviour (we've got two named instances running with several databases in each).
Any help / pointers appreciated.

The log for our SQL 2000 database shows constant "starting up database dbname" entires. Is there a option that causes the databases to constantly be starting or is this a new feature of SQL 2000.

I actually work in an organisation and we have to find a solution about the data consistancy in the database. our partners use to send details to the organisation and inserted directly in the database, so we want to create a new database as a buffer database to insert informations from the partners then make an update to the main database. is there a better solution instead of that?
View 6 Replies View RelatedHello everyone,I have a webcontrol that uses database-structures alot, it uses the system tables in SQL to read column information from tables. To ease the load of the SQL server I have a property that stores this information in a cache and everything works fine.I am doing some research to find if there are anyway to get information from the SQL server that the structure from a table has changed.I want to know if a column or table has changed any values, like datatype, name, properties, etc.Any suggestions out there ?!
View 3 Replies View RelatedI 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

View 3 Replies View RelatedHi All,
I am designing database where few of the master tables will reside in different database or in case different server. Scenario is
Server "A" with Database "A" may host the "Accounts" table.
Server "B" with Database "B" may host the "Product" table.
I am designing database "Project" which will hosted in Server "A".
My application requires this master tables [readonly access] as data inserted in my application refers this tables. Also there are reports to be generated which refer this tables.
How do i design my database and sql queries?
I am thinking of approach of having equivalent tables created in my database and writing service which keep tables in my database in sync. This will ensure good perfomance during transaction and reports as they will need to refer this table locally as opposed to different database or different server.
Any thoughts on above approach?? or any better/standard way for such scenarios ?
Thanks in Advance. Your inputs will be of great help.
Hello:
My client has a db with the following structure:
Online US Searchable Map of the 50 US States. Users search criteria is the following: Query records by selecting state, county, then record. Each County table has 10-20 tables. All databases combined = 500MB and TLogs = 100MB.
How would you re-design a relational DB where users could query data by state-county-record. Currenty the DB's are created by the County of each state which creates hundreds of DB's in SQLServer with no realtionship to each US state. What would be the best design to ensure good performance, data integrity and maintenance? Would you create 1 DB with all 50 states, create 4 DB's and divide by region(N,S,E,W), 50 DB's of each state or leave it as is with each county it's on DB? Any suggestions would be appreciated.
thx

Hello, I am designing my first database with 5 tables for a demo project and am not sure if it works. an example below.2 of the many things I want visitors to the site to do is find a company by the industry sector they belong to,..andwhat sort of service or products they can supply. For instance a Employment agency maybe under professional services Table 1 Customer Customer_ID = primary key,,,, Sector_ID = Foreign keyComapany Name, Address, Phone, Postcode etcTabel 2 Industry SectorsSector_ID = primary key,,,,Customer_ID= foreign key banking, Education,Prof Services, etc Table 3 Trading ActivityTrading_ID = primary key,,,,Sector_ID = Foreign key, Products_ID= FkEmployment Agent, School, Lawyer etcTable 4 ProductsProducts_ID = primary key,,,,Trading_ID = foreign keySupply frozen foods, transport services, sports goods, etc Table 5 Account Account_ID = primary key,,,,Customer_ID = foreign keyAccount Name, Credit Limit, Payment Terms, Open date, Account contact etc One big point of confusion is, can I have the Customer_ID from the principal Customers tablein every table as a foreign key or must the tables be chained together one after the other as such. Advice appreciatedThanks
View 1 Replies View RelatedHi,
I need a hand with designing a database.
I am collecting results from a survey which has the following questions:
Call ref? How did you place your support call? Were you satisfied with the amount of time you had to wait until getting acknowledgement of the support call placed? 1 = very satisfied and 10 = very unsatisfied. How happy were you with the customer service you received upon placing the support call? 1 = very unhappy and 10 = very happy.How satisfied were you with the amount of time you had to wait until you heard from an engineer? 1 = very satisfied and 10 = very unsatisfied. How satisfied were you with the time taken to get your problem/query resolved? 1 = very satisfied and 10 = very unsatisfied Did you feel the engineer had enough knowledge to deal with your call? 1 = very good and 10 = not very good Overall how satisfied were you with the support call placed? 1 = very satisfied and 10 = very unsatisfiedIs there anything we can do to improve the quality of the support and service you received?
I want to store this in a database. Obviously I want to use best practice for design, normalisation etc. The stumbling block I am coming accross is the fact that each question has a number and each question has a score from 1 to 10 and storing this in the database. Any help appreciated!
Thanks

View 2 Replies View RelatedI guess I am confused about something and need some help. I am looking at a database schema for about 20 tables in a database. I noticed that the firstcolumn in each table Is some type of Id. For example StudentId,TestId etc.Where the Id is a unique numeric sequential value.
So I have some questions?1- Do these Id's act as what are called indexes for the table?(Unique indexes)2- If the answer to 1 is correct, then how do I create these unique indexes? Is it as simple as declaring the Id column as the primary key and that this value will be generated automatically upon insert? 3- Is it necessary to have an Id column for every table, or may I only do it for a few of them?4. In relation to Question2, what do I need to do, so that the Id column will automatically be created when someone inserts a value into the database table with an ID column.
For example here are two sample tables
StudentsInfo
StudentId<PK> Name Age 1 Mark 33 2 Jill 23 3 Mary 25

The database will provide content management for an Intranet site.
On the site we have a number of articles which are categorised. Each categories can also have sub-categories.
The relationships would seem to be
Category---->Sub-Category----->Article
A category has one or mant sub-categories. A sub-category has one or many articles.
However some categories have articles but are no sub-categories.
Should I create a further relationship between Category and Article to cater for this instance or should their be a dummy category record in this instance?
