EXAM TIP Commit the objects in Table 20-1 to memory You will be tested on your knowledge of each of these objects There are a number of classes that assist with data representation, and they are independent of the source of the data (whether it be SQL Server, Oracle, or something else) These classes include DataRow and DataColumn, which as their names imply, represent rows and columns from a table (or spreadsheet), respectively There is also a DataTable class, which represents the collection of row and column data, and a DataRelation class, which acts as a link between two DataTable objects You can consider a DataTable to be a collection of DataRow objects, and a DataRelation to be the foreign-key representation between two DataTable objects EXAM TIP Be sure that you understand the source-specific classes for setting up the connection to your data These include SqlCommand and SqlConnection for specifying the SQL statements or stored procedures and the connection parameters when accessing Microsoft SQL Server 70 (and higher) databases In order to connect to an OLE/DB provider other than Microsoft SQL Server 70 (and higher), you would use OleDbCommand and OleDbConnection The classes specific to these two types of data stores are included in the ADONET object model If you wish to access data providers other than these types, you must download the ODBC classes from Microsoft

In this chapter we will present data-access concepts and applications using data retrieved from a Microsoft SQL Server, but you should keep in mind that Visual C# and, in particular, the NET Framework, allows you to access data from any source Sources include Microsoft SQL Server, Microsoft Access, Oracle databases, flat files, and so on That data can then, in turn, be bound to objects found in ADONET, such as a DataSet The data can be bound to any number of controls that support a data source property It can also be bound to arrays and collections The Visual Studio NET interface includes many built-in controls that allow you to create a link to a data source and then bind controls to the data retrieved from that source In this section, we will look at those controls and work with them to present a Windows Form that contains data from our SQL Server database College PART III

The Hypertext Transfer Protocol is at the heart of the Internet This is the protocol that gives us the ability to send information seamlessly between web browsers and web servers HTTP defines how a browser requests a web page and how the server responds to that request The standard defines two messages that are used for the communication The GET message is what the browser uses to request a page, and the POST message is what the server uses to respond to the browser On the surface, this looks straightforward the

The root element in an HTML page must be the HTML element It tells the browser to expect the document to contain HTML elements The HEAD element is used to contain information about the page For instance, the title of a page would be contained in a HEAD element This element is optional, but if it is used, it must be the first entry after the HTML element The TITLE element defines the text that will be displayed in the title bar of the browser The BODY element defines the part of the page that will be displayed Anything in the BODY element will be interpreted to be displayed The H1 element identifies the first heading level, and it specifies that the text in the element should be displayed with the largest, boldest font possible The HTML standard defines headings from H1 through to H6

browser sends a GET message and the server sends a POST message As you will see, however, the browser can also send POST messages that are interpreted as requests by the server An HTTP GET message is a maximum of 1,024 characters in length, and it contains the name and path of the document requested on the server In addition, it should include the browser s model and version, operating system version, screen resolution, username ( anonymous if not known), and a host of other information about the browser environment The POST message has a header that is a maximum of 1,024 characters in length, plus an unlimited body size POST messages are used to return requested items from the server to the browser, and are also used by FORM elements that are used by the browser to group fields together to return information to the server EXAM TIP The authors of the exams assume that you have a firm knowledge of HTML, specially the TABLE and FORM elements
