Help With The Design/creation Of A Database For My Application. [Experts Needed]
Apr 17, 2004Hello, I was wondering if any of you experts might assist me in properly creating a database for my application. I've been pondering for a few days on how to accomplish this, but it seems that it doesnt have to be as complex as I am thinking...I just have to know how.
First off, I want to populate a dataset from a database in which I can databind to a datalist or repeater control. My datalist or repeater will have the following information in the ItemTemplate. Each ItemTemplate will consist of a table with 1 row with 3 columns cells. In each cell, the data will be laid out as accordingly.
[Unique Number] [Description ][Price ]
1000 XYZ $100.00
1001 ZXY $250.00
When the datalist or repeater is populated, it will need to be tried against a value that the user selects. For instance, the user selects 100,000 from a listbox and fetches the next page which will show the diagram above...he/she will see those results. However, if the user selects 110,000, the diagram above will have for the most part the same Unique Number and Descriptions, but the prices will vary. The reason I say for the most part with the Unique Number and Descriptions, is because I want to later be able to add admin access to add additional rows and appropriate prices to each Unique Number and Description.
Now the tricky part is, I could just add the listbox values to a table as a unique key and associated them with the Unique Number, Description and Price, however there are about 50 different options the user can select from and approx 50 different rows of Unique Numbers, Descriptions and Price . So you can see, I would have to set up the diagram each time for every possible selection from the listbox, which wouldnt really be efficient I presume.
I want to be able to populate the datalist or repeater so it could have say 50 Unique Numbers with Descriptions and Price at selection 100,000. And also that it might only populate with 45 Unique Numbers and Descrptions and Price at selection 110,000 because the 5 missing dont pertain to the selection of 110,000. I am trying to do it this way because at sometime, I want the admin to be able to add/delete a Unique Number, a Description for it and a corresponding price that correlates to the selection from the listbox.
Thanks for all your help guys. I really appreciate it. For the most part I understand what Im doing, I just need to be walked thru it a bit. Thanks again!
Design Help Needed
Dec 21, 2005Hi, hoping someone can
give me a heads up on best sysyem to employ to manage this
scenario.Sorry if this is not the correct forum to post in.Our primary
software is a standalone VB6 app used by some 50 clients, each with
thier own MSDE backend. Their business basically is Packing and
distribution of fresh produce. Each of our clients have multiple
suppliers on which they have data stored. I have decided to write
a web app (VS2005) that will allow the supplier to enter critical
information about produce quality, testing etc. This data will be kept
on our local webserver database.My use case scenario is that
when a supplier enters a new record via web page I can somehow update the Packers
SQL database via internet, http,tcp.Ideally I imagine a trigger on our server db can connect to their databaseover WAN. HOW??The packer must also be able to add
suppliers to our server db. As they already have that data stored
stored at their end I was hoping to have a web page with drop down
lists that accesses their local db and, upon Save, updates our
webserver ddb. Thereby saving them the need to manually enter the
data twice. I know this is a little long winded but I'm new to .Net and
web programming so have no idea on the simplest and best method to do
this.Any help greatly appreciated.
Help Needed With Table Design.
Mar 4, 2008Hi there everyone,
I am starting to develop a new internal website for my company, for logging calls, reports and billings. I am still busy looking at the best way to design the layout of the DB.
My biggest concern is a billings table design. What it should do is, that when work was completed, the consultant must add his billings to the logged call. My problem is that i will never know how many individual items will be billed for. I was thinking of just creating a table with [id, call_id, item_1, cost_1, quan_1, item_2, cost_2, quan_2, item_3, cost_3, quan_3...........] but i think (hope) that there must be a better way of doing this.

Computed Column Design Help Needed
Apr 3, 2008
I have a Member table and I have a MemberView.
I want the view to return the "count" from a complex query related to the Member record and I'm looking for a good way to do that.
I was thinking:
select M.*, (select count(*) from UDF)
but that just smells bad.
Any pointers would be great.
Opinion About Design Needed (splitting String Data)
Dec 14, 2006Hi to everyone,My problem is, that I'm not so quite sure, which way should I go.The user is inputing by second part application a long string (let'ssay 128 characters), which are separated by semiclon.Example:A20;BU;AC40;MA50;E;E;IC;GREENNow: each from this position, is already defined in any other table, asa separate record. These are the keys lets say. It means, a have someproperities for A20, BU, aso.Because this long inputed string, is a property of device (whih alsohas a lot of different properities) I could do two different ways ofstoring data:1. By writing, in SP, just encapsulate each of the position separatedby semicolon, and write into a different table with index of device,and the position in long stirng nearly in this way:Major device data tableID AnyData1 AnyData2 ... AnyData3123 MZD12 XX77 .... any comment text124 MZD13 XY55 ... any other commentString data Tablefk_deviceId position value123 1 A20123 2 BU123 3 AC40.....123 8 GREENThe device table, contains also a pointer (position), which mightchange, to "hglight" specified position.Then, I can very easly find all necessary data. The problem is, I needto move the device record data (from other table) very often into otherhistory table (by each update). That will mean, that I also need tomove all these records from 1 -8 for example to a separate historytable, holding the index for a history device dataset. This is a littleinconvinience in this, and in my opinion, it will use to much storagedata, and by programming, I need always to shift this properities intohistory table, whith indexes to a history table of other properities.2. Table will be build nearly in this way:Major device data tableID AnyData1 AnyData2 ... AnyData3 stringProperty pointer123 MZD12 XX77 .... any comment text A20;BU;AC40;MA50;E;E;IC;GREEN 3124 MZD13 XY55 ... any other comment A20;BU;AC40;MA50;E;E;IC;GREEN 2By writng into device table, there will be just a additional field forthis string, and I will have a function, which according to specifiedpointer, will get me the string part on the fly, while I need it.This will not require the other table, and will reduce the amout ofdata, not a lot ... but always.This solution, has a inconvinance, that it will be not so fast doing asearch over the part of this strings, while there will be no real indexon this.If I woould like to search all devices, by which the curent pointervalue is equal GREEN, then I need to use function for getting thevalue, and this one will be not indexed, means, by a lot amount ofdata, might be slow.I would like to know Your opinion about booth solutions.Also, if you might point me the other problems with any of thissolution, I might not have noticed.With Best RegardsMatik

How to design tables in SQL Server for the above.
Database Design/query Design
Feb 13, 2002Ok, 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!
DB Design :: Buffer Database - Insert Information From Partners Then Make Update To Main Database

View 3 Replies View RelatedDesigning A Database Within A Database... Design Question Storing Data...
Jul 23, 2005I 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 RelatedDatabase Design- Referencing Multiple Database
Sep 27, 2007Hi 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.
Database Design - Multiple Vs. Single Database
Apr 12, 2007Hello:
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

Database Problems. Help Needed Please
Jan 6, 2008Guys,
Here my trouble I have for the weekend. I am working with SQL express in my local machine and everything is doing well. However, when I transfer the database to SQL 2005 in my host machine, I have this error. I checked on the internet and follow some of the suggestion I have, but not seems working. I ever remove the script I create using the aspnet_regsql, but still keep getting the same error. Please help. Any help is appreciated.
Below is the errors:
The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'. However, the current database schema is not compatible with this version. You may need to either install a compatible schema with aspnet_regsql.exe (available in the framework installation directory), or upgrade the provider to a newer version.
Still Can Not Acess Database. Help Needed. Thanks.

Jan 11, 2006Hi Gurus,
Can anyone assist?
How to recover the database if I have only the current transaction log and a older version of .mdf & .ldf files. No backup had being performed via Enterprise Manager.
I have installed MSSQL2000 on Windows 2003 Server. Created a new database 'sample' and inserted some data into the 'sample' db. Afterwhich, I offline the 'sample' db and copied the .mdf & .ldf to another backup directory.
Restart the database by bring it online again and continue to insert more data ... (approx 100,000 rows of data).
Afterwhich, I tried to damage the running database .mdf file and the database went into offline / suspect mode.
How can I recovered to the point in time of failure based on just current transactional log & older version of .mdf & .ldf files?
Can any gurus out there advises?
Database Owner Is Needed
Jul 16, 2006hi,
on 1 of my servers (actually, the dev. server I have setup up here at home), I must included the database owner everytime I select something or make a db call.
for example
select T.foo from K inner join T on T.id = K.id
must actualy be written like:
select dbo.T.foo from dbo.K inner join dbo.T on dbo.T.id = dbo.K.id
or else it wont work
what did I do wrong for this database owner thing to be a "must" when writing queries on this server.

in high safety mode when safety is full if for some reason communication between principal and mirror is broken for say 2 days then principal will keep working but in disconnected mode. When communication link will establish again then principal can see the mirror server
1. Will establish the mirroring automatically?
2. Then will it synchronise the mirror databases automatically?
3. If it will synchronise databases automatically then principal will process transaction
or wait till principal-mirror will be in synchronised state which again depends on
number of transaction need to redo on mirror?

What Permissions Are Needed To Drop All Connections On A Database?
Oct 6, 2006I'm looking for the correct permissions to grant a user the ability to be able to drop all connections on a database.
The following code throws an exception:
Dim srv As New Server(SqlServerName)
If srv.Databases.Contains(siDBName) Then
srv.KillAllProcesses(siDBName) '== the srv.KillDatabase will not work here, we must kill the processes first
Dim db As Database = srv.Databases(siDBName)
db.Drop()
End If
Throws the Exception:
Microsoft.SqlServer.Management.Smo.FailedOperationException:

The user does not have permission to perform this action.
This code DOES NOT throw an exception when run as an Administrator.
Any Ideas?
Database Administration/Maintenance - Guidance Needed
May 16, 2006I have been working SQL server for many years as a web developer, however in my current position we are lacking an expert in maintenance and admninistration as the company has recently switched over to SQL Server 2005.
I therefore need to develop a greater understanding of the best practices with regards to administration and am a bit lost as there are so many options which seem like they might match my requirements. As I have never looked beyond the basic administration/maintenance side of things before I have no idea which options to investigate.
Basically I want to clear any records older than 3 months old on a scheduled/automatic basis. There seem to be various options that could do this, however I want to know what the best option is, rather than waste a lot of time and risk problems by resorting to trial and error.
We are already backing up this data, however I am not sure if I should combine these tasks. It is highly unlikely that we will ever have to restore these older records, however we do need to store the data for legal reasons.
I dont expect anyone to tell me everything, as I am happy to investigate, I just need a nudge in the right direction.
Thanks

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

Apr 10, 2007Hi,
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!

Jan 30, 2008I 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.
