WSE 3.0 provides a framework to authorize users and roles. Similar to other security configuration features in WSE 3.0, you can do this using either a policy file or code. Figure 3-20.

There s no business requirement to differentiate between an empty value and one that was never entered, so Null values would make no sense. The table also has a LastChanged column, which will be used to implement otimistic, first-writewins concurrency in 18. It is of type timestamp, so it provides a unique, auto-incrementing value every time a row is inserted or updated. All the tables in the PTracker database will have this type of column.

The StockTrader.asmx Web service authenticates users through a custom username token manager, but no further security checks are performed after the user is successfully identified. You will now configure this Web service to validate whether the user is authorized to access the services provided by the StockTrader service. The simplest way to do this is through a policy file, as shown in the following steps: 1. In the wse3policyCache.config file, add the following elements under the <policy> section: <authorization> <allow user="admin" /> <deny user="*" /> </authorization> 2. In the same file, under the <extensions> section, add the following line: <extension name="authorization" type="Microsoft.Web.Services3.Design.AuthorizationAssertion, Microsoft.Web.Services3, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> The <authorization> tag allows you to grant or deny access to the service based on the user s name or role. You can test this by modifying the code in the console application to use a different username, such as guest. If you run the application, it will throw an exception that displays the message Microsoft.Web.Services3.Security.SecurityFault: User guest is not authorized to access the service. Figure 3-21. Design of the Projects table The Id column is set up as the primary key, and it s of type uniqueidentifier, which is a Guid type in .NET. There are many ways to create primary key columns in tables, including using auto-incrementing numeric values or user-assigned values. However, the use of a uniqueidentifier is particularly powerful when working with object-oriented designs. Other techniques don t assign the identifier until the data is added to the database, or they allow the user to provide the value, which means that you can t tell if it collides with an existing key value until the data is added to the database. With a uniqueidentifier, however, the business developer can write code to assign the primary key value to an object as the object is created. There s no need to wait until the object is inserted into the database to get or confirm the value. If the value isn t assigned ahead of time, the database will supply the value. Notice that the two datetime fields allow Null values. The Null value is used here to indicate an empty value for a date. The Description column is also allowed to be Null. This isn t because of any business requirement but rather because it is quite common for database columns to allow Null values in cases in which they re meaningless. 18 will illustrate how to easily ignore any Null values in this column. The Description column is of type varchar(MAX) so that it can hold a blob of text data. This field allows the user to enter a lengthy description of the project, if so desired. The Resources table will hold the data for the various resources that can be assigned to a project. Figure 3-22 shows the columns for this table. onOpen() or onCreate() implementations.
