The Active Directory database mounting tool allows you to view AD DS data that is stored in snapshots or backups online. You can then compare data in snapshots or backups from different points in time, which will help you to make a better decision about what data to restore. The Active Directory database mounting tool makes it possible for you to save deleted AD DS or Active Directory Lightweight Directory Services (AD LDS) in the form of snapshots taken by the Volume Shadow Copy Service (VSS). The tool does not actually recover the deleted objects and containers you must perform data recovery as a separate step. Because backups contain sensitive data, the backups are stored as read-only and only members of the Domain Admins and Enterprise Admins groups are allowed to view the snapshot with a Lightweight Directory Access Protocol (LDAP) tool such as Ldp.exe. I recommend that you use encryption or other data security precautions with AD DS snapshots to help mitigate the chance of unauthorized access to AD DS snapshots. To use the Active Directory database mounting tool, follow these steps: 1. Schedule a task that regularly runs Ntdsutil.exe to take snapshots of the volume that contains the AD DS database. This is optional. You can do it manually if you want, but I recommend scheduling it. 2. Run Ntdsutil.exe to list the available snapshots and mount the snapshot that you want to view. 3. Run Dsamain.exe to see the snapshot volume as an LDAP server. For example, if I want to see my latest snapshot in the default path, the command will be: dsamain dbpath c:\$snap_200711201220_volumec$\windows\ntds\ntds.dit ldapport 41389. This will make the snapshot available for Ldp.exe on port 41389. Dsamain.exe will take the following arguments:

In this chapter, we ll cover setting up three essential open-source tools: Hibernate; MySQL, the most popular open-source database; and Ant, the premier Java build tool. Ant isn t strictly necessary for our example project, but it can make life easier; not using it would be like coding with one hand tied behind your back.

consists of the values of the clustered index keys from the pointed row, and the uniquifier (if present). The idea is to point to a row "logically" as opposed to "physically." This architecture was designed mainly for OLTP systems, where clustered indexes often suffer from many page splits upon data insertions. In a page split, half the rows from the split page are physically moved to a newly allocated page. If nonclustered indexes kept physical pointers to rows, all pointers to the data rows that moved would have to be changed to reflect their new physical locationsand that's true for all relevant pointers in all nonclustered indexes. Instead, SQL Server maintains logical pointers that don't change when data rows physically move. Figure 3-20 illustrates what the PK_Orders nonclustered index might look like; the index is defined with the orderid as the key column, and the Orders table has a clustered index defined with the orderdate as the key column.

When you write an indexer in C#, its getter and setter turn into methods called get_Item and set_Item.

is responsible for managing data and changes to that data The reason we use a database instead of simply a flat file is that a database can offer a lot of benefits, primarily in the areas of integrity, performance, and security Integrity Integrity is probably the most important benefit, as without it not much else matters If our data isn t consistent, reliable, and correct, then it is less valuable to us or possibly even useless Databases achieve integrity by using strong data types, enforcing constraints, and working within transactions Databases are strongly typed, which means that when a database table is created, its columns are configured to store a specific type of data The database management system ensures that the data stored in the tables are valid for the column types For example, a table might define a column as VARCHAR(25) NOT NULL.
