Application roles restrict users to access data through a specific application only. Database permissions can be gained only by using specific applications and a user cannot logon directly to a database.

Application security and Application roles contain no members. Users, Microsoft Windows NT groups, and roles cannot be added to application roles. The permissions of application roles can be achieved when the application role is activated for the user’s connection through a specific application. A user’s association with an application role is due to the capability of running an application that activates the role, instead of being a member of the role. It is necessary for a connection to lose default permissions applied through the login/user account or database roles for the duration of the connection, and gain the permissions associated with the application role, so that all functions of the application can be performed without any permission conflict. For example, if a user is denied access to a table the application must access, the denied access should be revoked for the user to successfully use the application. Application roles overcome any conflicts with user’s default permissions by temporarily suspending the user’s default permissions and assigning them only the permissions of the application role.

Trace.axd is an Http Handler that can be used to view the trace details for an application. This file resides in the application’s root directory. A request to this file through a browser displays the trace log of the last n requests in time-order, where n is an integer determined by the value set by requestLimit=”[n]” in the application’s configuration file.

The SystemProcessor Queue Length counter displays the number of threads ready in the processor queue but not currently able to use the processor. The Processor: %Processor Time counter should be measured with a counter. If its value is two, it indicates a CPU bottleneck. This results in slow performance of the server. To eliminate the performance problem, several steps can be used such as reducing the number of processors, using = multiple processors, updating the processors, or installing new and updated CPUs.

The FROM clause of the SQL SELECT statement is used to specify the table names that will be joined together to extract the data values. For example:

SELECT <attributes>
FROM <tables>
WHERE <condition>

The ExecuteNonQuery method of the SqlCommand class is used to execute commands that change a database. These commands include the Transact-SQL INSERT, UPDATE, DELETE, and SET statements. The method acts directly on a database connection and does not require a data set. It returns an integer that indicates the number of rows affected by the execution of a command. This method can also be used to perform catalog operations, such as querying the structure of a database or creating database objects.

The GetChildRows method of the DataRow class is used to get the child rows of a DataRow object. The DataRow class defines four overloaded versions of the method. Their signatures are as follows:

Signature Description
Overloads Public Function GetChildRows(DataRelation) It is used to get the child rows of a DataRow by using the specified DataRelation, which is passed as a parameter to the method.
Overloads Public Function GetChildRows(String) It is used to get the child rows of a DataRow by using the specified RelationName of a DataRelation.
Overloads Public Function GetChildRows(DataRelation, DataRowVersion) It is used to get the child rows of a DataRow by using the specified DataRelation and DataRowVersion.
Overloads Public Function GetChildRows(String, DataRowVersion) It is used to get the child rows of a DataRow by using the specified RelationName of a DataRelation and DataRowVersion.

All the versions of the method return an array of DataRow objects.

The MessageName property of the WebMethod attribute is used to give an alias name to an XML Web service method. It is generally used to uniquely identify overloaded Web methods. By default, the MessageName property for a Web method is set to the name of the method. However, if an XML Web service contains two or more Web methods with the same name, individual Web methods are uniquely identified by setting MessageName to a name that is unique within that XML Web service. The SOAP message uses the name, which is used in the MessageName property for a method as the method name instead of the actual method name.

Following is the syntax for the WriteXml(string, XmlWriteMode) method of the DataSet class:

datasetobjectname.WriteXml(filename, mode);

where, datasetobjectname specifies the name of the DataSet object, filename specifies the name of the file, including the path, to which to write data, and mode specifies an XmlWriteMode value. Following are the values that can be used for XmlWriteMode:

XmlWriteMode value Description
DiffGram It specifies that a DataSet has to be written as a DiffGram containing current and original values.
WriteSchema It specifies that only the current values of a DataSet have to be written as XML data with the relational structure as inline XSD schema. It is the default XmlWriteMode.
IgnoreSchema It specifies that only the current values of a DataSet have to be written as XML data without an XSD schema.
