You can also view table data or create your own queries either by hand or graphically via the Query Builder. By adding a database to the Server Explorer you can add tables, stored procedures, views, and so on all from within Visual Studio. With the web site created, the next step is to add a reference to the database in Visual Studio's Server Explorer. This will create a new web site with a Default.aspx ASP.NET page and an App_Data folder. Choose the ASP.NET Web Site template, set the Location drop-down list to File System, choose a folder to place the web site, and set the language to C#.įigure 1: Create a New File System-Based Web Site ( Click to view full-size image) To accomplish this, go to the File menu and choose New Web Site, displaying the New Web Site dialog box. Start by creating a new file system-based ASP.NET web site. We've got a lot to cover in this first tutorial, so fire up Visual Studio and let's get started! Step 1: Creating a Web Project and Connecting to the Databaseīefore we can create our Data Access Layer (DAL), we first need to create a web site and setup our database. The tutorials after the third one will build upon the foundation laid in the first three. In this tutorial we'll start from the very beginning and create the Data Access Layer (DAL), followed by creating the Business Logic Layer (BLL) in the second tutorial, and working on page layout and navigation in the third. However, all of the tutorials will work equally well with the free version of Visual Studio 2005, Visual Web Developer. The web application was built using Visual Studio 2005 Professional Edition as a file system-based Web site project. If you use a different SQL Server version of the Northwind database, you will need to update the NORTHWNDConnectionString setting in the application's Web.config file. In addition to the database file, the App_Data folder also contains the SQL scripts for creating the database, in case you want to use a different database version. (This first tutorial is quite lengthy, but the rest are presented in much more digestible chunks.)įor these tutorials we'll be using a Microsoft SQL Server 2005 Express Edition version of the Northwind database placed in the App_Data directory. Each tutorial is available in C# and Visual Basic versions and includes a download of the complete code used. These tutorials are geared to be concise and provide step-by-step instructions with plenty of screen shots to walk you through the process visually. Once this backend groundwork has been laid, we'll move into reporting, showing how to display, summarize, collect, and validate data from a web application. We'll start with creating a software architecture composed of a Data Access Layer (DAL) using Typed DataSets, a Business Logic Layer (BLL) that enforces custom business rules, and a presentation layer composed of ASP.NET pages that share a common page layout. This is the first tutorial in a lengthy series that will explore techniques for implementing these common patterns in ASP.NET 2.0. We create databases to store the data, code to retrieve and modify it, and web pages to collect and summarize it. IntroductionĪs web developers, our lives revolve around working with data. ASP.NET applications can store various types of website state in an Oracle database, which can then be shared across the application.In this tutorial we'll start from the very beginning and create the Data Access Layer (DAL), using typed DataSets, to access the information in a database.
