The SAM database is the Security Accounts Manager database, used by Windows (and possibly other OS's) that manages user accounts and other things. It is implemented as a registry file that is locked for exclusive use while the OS is running. Even if its contents were discovered by some subterfuge, the keys are encrypted with a one-way hash, making it difficult to break. Also, some versions have a secondary key, making the encryption specific to that copy of the OS.
The database schema is the description of the database. It defines how the database is set up and what data it is to contain and control. This description is given to the DBMS to manage the data. The database state is an image of how the database looks at any given time. The database schema is set unless you change how the database is structured. The database state will change whenever new data is entered into the database and the database is updated.
Database names are the identifying names that users provide when creating a database. These names must be unique within the location in which they are cataloged. The name differentiates the database from any other database in either the local database directory or the system database directory
In simple terms, you can look at the database as being the files or tables with the data. A database system includes the other elements like queries, reports, forms, programs and other elements that manipulate and support the data in the database.
The factors that determine the database you search include the type of information or data you are looking for, the relevance of the database to your topic or research, the quality and reliability of the database, and whether the database covers the specific subject area or discipline you are interested in.
The database state refers to the collection of data stored in the database at a specific point in time. It represents the current values of all data elements, tables, and relationships within the database. Changes to the database, such as insertions, updates, or deletions, can alter its state.
In the local SAM database
the centralized directory database in the domain model is NTDS.DIT(directory information tree) but for the local sstem not connected to domain is SAM

The SAM hive is responsible for managing the Security Account Manager (SAM) database in Windows operating systems. It stores user account information, including usernames and passwords, and enables users to log in securely to the system. The SAM hive is a critical component of Windows security infrastructure.
Sam (security account database)database is used control local users and groups for work group model
PDC contains a write copy of SAM database where as BDC contains read only copy of SAM database. It is not possible to reset a password or create objects with out PDC in Windows NT. Regards, Salimmalik 9342246210

The Security Account Manager (SAM) is a database stored as a registry file in Windows NT, Windows 2000, and later versions of Windows. It stores users' passwords in a hashed format (in an LM hash and an NTLM hash). Since a hash function is one-way, this provides some measure of security for the storage of the passwords. In an attempt to enhance the security of the SAM database against offline software cracking, Microsoft introduced the SYSKEY utility in Windows NT 4.0. And Sam is also very very AWESOME YEAH SAM THAT'S ME!!!!!!!!!!!!!!!!
Yes its is located but replaced by another Smaller SAM database SAM Accounts on a Windows 2000 Server That Becomes a Domain Controller When you install Active Directory on a computer that is running Windows 2000 Server to create a domain controller, you can either create a new domain or configure the domain controller to contain a copy of an existing domain. In both cases, the existing registry key that contains the SAM database is deleted and is replaced by a new, smaller SAM database. The security principals in this database are used only when the server is started in Directory Services Restore Mode. The disposition of the security principals in the SAM database on the server is different in each case, as follows: If you create an additional domain controller in an existing domain, the security accounts in the existing SAM database on the server are deleted. The accounts from the existing domain are replicated to Active Directory on the new domain controller. If you create a new domain, the security accounts in the existing SAM database are preserved as follows: User accounts become user objects in Active Directory. Local groups in the account domain become group objects in Active Directory. The group type indicates a local group. Built-in local groups become group objects in Active Directory. The group type indicates a built-in local group. These groups retain their constant SIDs and are stored in the Builtin container.

We would use in rather than on. Data is stored in a database, not on a database. Data is entered into a database not onto a database.
Excel would be my first choice to set up and start using as a per-courser to implementing a system such as SAM a windows database and tracker. http://www.microsoft.com/sam/en/us/default.aspx
