Recurring Appointments Calendar Design (was The Most Challenging Project)
Jan 14, 2005Hello,
This is my first project at the company I recently joined. It is the most challenging project I ever had.
It is a kind of web-scheduler.
it let you save appointments which could be one time or periodic.
For example, it could be like every monday, every other monday, first tuesday every monday, and so on.
once they are saved, it should be able to display only those appointments the user have on a specific day.
I'd like to know how database has to be designed to meet such a challenging requirement?
I'd like to hear anything from you if you have had similar project before.
Thank you,
Charlie
How To Go From A Database To A Calendar Format?
Jul 23, 2005HelloMy department has a SQL server database that is used to all facets ofproduction within our department. This includes key production jobsteps, project names, numbers and descriptions.The calendar is currently done manually as an Excel document. The userrecieves hard copies of the required information, then keys it into theappropriate place on the Excel document.We would like to pull information out of that database, and put it in amonthly calendar format. For example, take a project name and the dateassociated with that project, and put it on a calendar in theappropriate date "square".If you have information or experience with software that can be used toaccomplish this task, I would appreciate hearing your advice.Thanks in advance.

Dec 11, 2005Hi,I m trying to implement a calendar, where you can select certain dates and view list of events for that day. The list is generated from database. I found a script on the web that is quite similar to what i want to achieve. I tried to run this script, however I get an exeption saying:An error has occurred while establishing a connection to the server. .... error: 40 - Could not open a connection to SQL Server)This is the code:SqlConnection mycn; SqlDataAdapter myda; DataSet ds = new DataSet(); DataSet dsSelDate; String strConn; private void Page_Load(object sender, System.EventArgs e) { // Put user code to initialize the page here strConn = "Data Source=localhost;Initial Catalog=pubs"; mycn = new SqlConnection(strConn); myda = new SqlDataAdapter("Select * FROM EventsTable", mycn); myda.Fill(ds, "Table"); //This where I get the exeption } protected void CalendarDRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e) { // If the month is CurrentMonth if (!e.Day.IsOtherMonth) { foreach (DataRow dr in ds.Tables[0].Rows) { if ((dr["EventDate"].ToString() != DBNull.Value.ToString())) { DateTime dtEvent = (DateTime)dr["EventDate"]; if (dtEvent.Equals(e.Day.Date)) { e.Cell.BackColor = System.Drawing.Color.PaleVioletRed; } } } } //If the month is not CurrentMonth then hide the Dates else { e.Cell.Text = ""; } } private void Calendar1_SelectionChanged(object sender, System.EventArgs e) { myda = new SqlDataAdapter("Select * from EventsTable where EventDate='" + Calendar1.SelectedDate.ToString() + "'", mycn); dsSelDate = new DataSet(); myda.Fill(dsSelDate, "AllTables"); if (dsSelDate.Tables[0].Rows.Count == 0) { DataGrid1.Visible = false; } else { DataGrid1.Visible = true; DataGrid1.DataSource = dsSelDate; DataGrid1.DataBind(); } }

Concert Calendar/reviews Database Development?
May 2, 2008Hi,
I'm neck-deep in trying to normalize all the info I need into separate tables, but I seem to have hit a wall running.
I was curious as to what the "best" way is to develop a database of concert events would be? What I think I've figured so far would be if I created a table called events...that would be 1 row of data per concert event. Each row could then have a 'event_id' as PK, 'date', and a column with the associated 'band_id' from the bands table. Then anytime the date was accessed (assuming a populated row for that date), a list of concerts for that date would show.
I would also like to use the 'event_id' as an access point for my reviews table...where, quite obviously, I would like to be able to have reviews associated with each event from the calendar as well. Does all this seem right? Or is there a better way (i.e. more efficient, smaller database, and/or use less memory)? How, for example (in short, obviously), does a website like Pollstar.com database their events?
I guess my question with regards to this database is also...within my bands table, should I include their tour dates? Or should I put the band_id in my events table?
I was hoping to get a just a little bit of direction so I don't turn some baby missteps into a long-term project down the wrong road. Any help or response is greatly appreciated. Thanks again!
SQL Express Vs SQL Standard For Hotel Booking Web App...
Nov 28, 2006We are developing a new online booking system with asp.net and looking for optiosn for the data store. Currently the PHP applciation utlizes MySQL but we would like to use SQL Server in the rewrite.
What limitations would we run into with Express over Standard for such a system? Is the 4GB size limit and advanced SQl features such as replication, etc the only differences? We are looking for something to run on a dedicated or VPS based Windows server that will only be running our app and database. System is an online hotel type booking system with approx 7000-12000 transactions per month which may double in the coming year.
Express certainly has a cost advantage but we don't want to run into issues with this version if there are any we should watch out for.

Advice For Storing Reservation/booking Date Ranges...
May 19, 2005I am building a small app that will display availability data for properties. I have a calendar that displays the dates for a whole year in month rows with each days colour representing the availability status, i.e. booked, on hold etc.
My question is about how to store these dates in the db. At the moment I have the table below:
TABLE Availability [PropertyID] [int] NOT NULL , [StatusID] [tinyint] NOT NULL , [StartDate] [smalldatetime] NOT NULL , [EndDate] [smalldatetime] NOT NULL
I was planning on having four status's for any given date, unknown, available, on hold or booked.
Displaying the dates has proved pretty simple but updating availability means I would need to query the db to see if any of the dates overlapped, I would then have to add the new date range/status as well as change any date ranges that overlapped, either in the sp or in the code and this is what made me wonder if there was a better way.
Does this sound a reasonable approach? Any advice or pointers would be greatly appreciated, This is the first time I have had to store date ranges and I want to make sure I am doing it right.

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!

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

Oct 20, 2006Hello, 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.

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!
Thanks

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.
For example here are two sample tables

Database Design -
Dec 13, 2000The 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?
