Weather Station Database Design, Receiving Every Second Sensor Data?
Dec 11, 2010
If I store the data every second, the database will grow rapidly. I need to have less detail of measurements of a few weeks/months back. An average would be enough. I have 5 sensors: wind speed, wind direction, temperature, light and rain. How would I design my database?

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?
I'm working on a project that has a C# app (running 24/7 as a server) on the client's machine). This app needs to send a file as a byte stream via POST to a server I am currently hosting on my home desktop.
Can this file be received by a C# app running on my server, or does it have to be as ASP app/page?
Also, I know how to send a bytestream via POST, but how will I set my server side app to listen for this incoming data? I have never done something like this, so I'm looking for some pointers to get me started.
I have implemented a generic handler to work as a restful web service in ASP.Net. I have a problem receiving the XML file that is being posted to this web service. I cannot actually see anything being passed. I have gone through the form, querystring, and file properties of the request object. Everything is empty. I know that the file has been posted correctly because I can see it while using a port sniffer.
I am working on a client - server application and in which I used to send and receive data through SOAP web service.
Now after sometimes I have heard from someone that I might lost some data while this process on soap service created in ASP.net. So now I have decided to send and receive data through batches like first I will send List of 50 objects and then next 50 and so on...
Now I am new to web services and all.
So my question is "Is it true that we can lost some data sometimes while transferring it through SOAP web service?"
I have an application that needs to post data to a url on the web and then receive an xml response. I have an HTML form (provided by vendor) that posts the data correctly, however when clicking the submit button the page is redirected to the post url and the xml is displayed in the browser. I need to do this on a postback within an existing asp.net project. Basically, the user will fill out the form, the form data will post to the url, the xml response will be received, and the appropriate values will be displayed on the screen. I've found a bunch of examples for doing this but I just can't seem to get my head around it. Can anyone point me in the right direction or explain how I should go about this?

I am starting a new project in ASP.NET (With silverlight) - I would like to get expert opinion about how to design the data access.I can use DataAccess Layer with SQL helper, but the challenge is every new field that I add needs to be added in the sql helper.I am trying to see if there is a way to design the system, so that it appears in the front end when a new field is added. I don't want to have in the ASPX files (binding in controls) I want to have ability to change items in code. Essentially I am trying to see the best option to have a database application.

I want to design a database of chemical material. As every body knows that the chemical material has more than 20 variety of features such as color, molecular weight,temperature,pressure,pH, etc. I learn that all of features was designed into description item in some database,but I think it is not an easy way to research.
