The side-by-side upgrade method offers several advantages over the in-place method. The major advantage is that if something goes wrong with the upgrade, or unexpected results render the upgrade a failure, the legacy instance is still available and unchanged for rollback purposes. Further, the upgrade is granular; individual databases can be migrated with others remaining on the original server, migrated to a different server, or migrated at a later point. Disadvantages and complexities of this method when compared to the in-place method are as follows: Application connection strings will need to be modified to point to the new instance name. Security settings, maintenance plans, and SQL Server Agent jobs will need to be re-created on the new 2008 instance, either manually or from a script. If the new 2008 instance is on the same server as the legacy instance, the capacity of the server to run both instances in parallel must be taken into account. A possible workaround for this issue is to limit the resources of one of the instances, such as the maximum memory and CPU affinity, for the period of time that both are actively running. Downtime is typically longer than for an in-place method; there are several techniques used to limit this, as you ll learn in a moment. Side-by-side upgrades are often scheduled for the same time as server replacements that is, the new server is purchased, installed, configured, and loaded with a new

C# provides a feature called the anonymous type that directly relates to LINQ As the name implies, an anonymous type is a class that has no name Its primary use is to create an object returned by the select clause Often, the outcome of a query is a sequence of objects that are either a composite of two (or more) data sources (such as in the case of join) or include a subset of the members of one data source In either case, often the type of the object being returned is needed only because of the query and is not used elsewhere in the program In this case, using an anonymous type eliminates the need to declare a class that will be used simply to hold the outcome of the query An anonymous type is created through the use of this general form: new { nameA = valueA, nameB = valueB, } Here, the names specify identifiers that translate into read-only properties that are initialized by the values For example,

new { Count = 10, Max = 100, Min = 0 }

In multiple mode, recognition results are returned to the browser in regular intervals of time This mode suits such situations as when input is in the form of a dictation, with silence occurring between two phrases spoken by the user The recognition process continues until the application generates an explicit stop call Multiple mode may be defined by using the following schema:

instance of SQL Server 2008, and databases are migrated from the legacy instance At the completion of this process, the legacy server is decommissioned, cycled back to lower environments, or used for other purposes The method used to migrate databases as part of a side-by-side upgrade is an important consideration in determining the rollback and downtime implications for the upgrade, particularly for larger databases Let s walk through the major methods used, beginning with backup/restore BACKUP/RESTORE The backup/restore method is straightforward and keeps the original database in place for rollback purposes A full database backup is made on the legacy database and restored to the new SQL Server 2008 instance As part of the restore process, SQL Server will upgrade the internal structures of the database as necessary A variation on this approach involves filegroup backups and piecemeal restores.

This creates a class type that has three public read-only properties: Count, Max, and Min These are given the values 10, 100, and 0, respectively These properties can be referred to by name by other code Notice that an anonymous type uses object initializers to initialize the properties As explained in 8, object initializers provide a way to initialize an object without explicitly invoking a constructor This is necessary in the case of anonymous types because there is no way to explicitly call a constructor (Recall that constructors have the same name as their class In the case of an anonymous class, there is no name So, how would you invoke the constructor ) Because an anonymous type has no name, you must use an implicitly typed variable to refer to it This lets the compiler infer the proper type For example,

var myOb = new { Count = 10, Max = 100, Min = 0 }

creates a variable called myOb that is assigned a reference to the object created by the anonymous type expression This means that the following statements are legal:

ConsoleWriteLine("Count is " + myObCount); if(i <= myObMax && i >= myObMin) //
