5. 1. How many files can a Database contain in SQL Server? How
many types of data files exists in SQL Server? How many of those
files can exist for a single database?
A Database can contain a maximum of 32,767 files.
There are Primarily 2 types of data files Primary data file and Secondary data
file(s)
There can be only one Primary data file and multiple secondary data files as
long as the total # of files is less than 32,767 files
2. What is DCL?
DCL stands for Data Control Language.
3. What are the commands used in DCL?
GRANT, DENY and REVOKE.
4. What is Fill Factor?
Fill Factor is a setting that is applicable to Indexes in SQL Server. The fill
factor value determines how much data is written to an index page when it is
created / rebuilt.
6. 5. What is the default fill factor value?
By default the fill factor value is set to 0.
6. Where do you find the default Index fill factor and how to change
it?
The easiest way to find and change the default fill factor value is from
Management Studio, right-click the SQL Server and chooses properties. In the
Server Properties, choose Database Settings, you should see the default fill
factor value in the top section. You can change to a desired value there and
click OK to save the changes.
The other option of viewing and changing this value is using sp_configure.
7. What is a system database and what is a user database?
System databases are the default databases that are installed when the SQL
Server is installed. Basically there are 4 system databases: Master, MSDB,
TempDB and Model. It is highly recommended that these databases are not
modified or altered for smooth functioning of the SQL System.A user database
is a database that we create to store data and start working with the data.
7. 8. What are the recovery models for a database?
There are 3 recovery models available for a database. Full, Bulk-Logged and
Simple are the three recovery models available.
9. What is the importance of a recovery model?
Primarily, recovery model is chosen keeping in view the amount of data loss one
can afford to. If one expects to have minimal or no data loss, choosing the Full
recovery model is a good choice. Depending on the recovery model of a
database, the behaviour of database log file changes. I would recommend you
read more material on log backups and log file behaviour and so on to
understand in depth
10. What is Replication?
Replication is a feature in SQL Server that helps us publish database objects
and data and copy (replicate) it to one or more destinations. It is often
considered as one of the High-Availability options. One of the advantages with
Replication is that it can be configured on databases which are in simple
recovery model.
8. 11. What the different types of Replication and why are they used?
There are basically 3 types of replication: Snapshot, Transactional and Merge
Replication. The type of Replication you choose depends on the requirements
and/or the goals one is trying to achieve. For example Snapshot Replication is
useful only when the data inside the tables does not change frequently and the
amount of data is not too large, such as a monthly summary table or a product
list table etc. Transactional Replication would useful when maintaining a copy of
a transactional table such as sales order tables etc. Merge Replication is more
useful in case of remote / distributed systems where the data flow can be from
multiple sites, for example sales done at promotional events which might not be
connected to the central servers always.
12. What the different components in Replication and what is their
use?
The 3 main components in Replication are Publisher, Distributor and Subscriber.
Publisher is the data source of a publication. Distributor is responsible for
distributing the database objects to one or more destinations. Subscriber is the
destination where the publisher’s data is copied / replicated.
9. 13. What the different Topologies in which Replication can be
configured?
Replication can be configured in any topology depending keeping in view of the
complexity and the workload of the entire Replication. It can be any of the
following:
Publisher, Distributor and Subscriber on the same SQL Instance.
Publisher and Distributor on the same SQL Instance and Subscriber on a
separate Instance.
Publisher, Distributor and Subscriber on individual SQL Instances.
14. How do you open a Cluster Administrator?
From Start -> Run and type CluAdmin (case insensitive) and the Cluster
Administrator console is displayed OR you can also go to Start -> All programs
-> Administrative Tools -> Cluster Administrator
10. 15. What are the different ways you can create Databases in SQL
Server?
T-SQL; Create Database command.
Using Management Studio
Restoring a database backup
Copy Database wizard
