Teradata is
designed with many features, to protect your data against the potential data
loss. Each feature protects your data in a different scenario. Inbuilt it
activates some of the features that should be tuned. Now we will discuss what
are sources that it offered to protect your data. Teradata training will
help you to master its core concepts.
RAID
The RAID is
known as redundant array of Independent disks in a mechanism. It used to
protect your data from the disk failures. The Disk array consists of a set of Disks,
which grouped as a logical unit. This unit looks like a single unit to the
user, but they may be distributed across multiple disks.
Hot
Standby Node
Hot standby
node is a node that does not participate in the production Environment. If a
node fails, then the Vprocs from the failed nodes, they will transfer to the hot
standby node. Once if the failed node is recovered, it will become like a hot
stand by the node. Hot stand by Node used to handle the performance when the
node failure occurs. Teradata is the best to examine your
skills in it.
Cliques
Clique is a standard mechanism used by the Teradata for protecting data from the node
failures. A clique is simple, but it is a combination, which shares a similar
set of disk arrays. When a node fails, the Vprocs with interrupting node. It
will transfer to other nodes in the clique and it continues to access their
disk array.
Down
AMP Recovery Journal
The Down
AMP is a recovery journal, which is activated when amp failure happens. In
addition, the table is fall back secured. This type of journal will keep a
track of each change of all data types in the Interrupted AMP. The journal is
Switch on the remaining AMPs in Cluster. It is an automatic process and it
cannot be switched off. If the failed AMP is live, then the data from the AMP
recovery Journal is updated with AMP. After this process, the Journal is
discarded.
Fall
back
It
considered a protected sheet. The fall back will protect the table of data by
storing the second type of copy. The copy is a set of rows of a table on
another AMP it is called as fall back AMP. If one AMP fails, then the fall back
rows will be accessed. With this, if the only single amp is failed, data is
still available with Fall back amp. The fall back amp is utilized at a table
design or after the table design. Fall back initiates that the second copy of rows.
Alternatively, after the table design stored in another AMP for protecting the
data from AMP failure. However,
the fall back will occupy more than one store and the I/O updates and Delete.
Transient Journal
Tera data utilizes the transient
Journal for protecting the data when the transaction fails. If a transaction
fails or when any type of transaction run, the transient journal will keep a
copy, before the images of affected rows, when the transaction is a success or it
rolled back with more success. Then the images before were terminated.
Transient Journal kept in every AMP. It considered as an automatic process and
it cannot stop.
Information security is considered as
a big priority and difficult for many companies. It is considered as a
competitive thing. Teradata approaches with information security that contains an
orchestrated combination of technology, it considered as the best practice
methods.
Successful record of
accomplishment
Teradata systems regularly operated
and moved with information and data with security standards. This includes the
PCI data security standard that is U.S.DoD DIACAP and DISA security. It also
has HIPAA security and data privacy terms and conditions, FDA 21 CFR part 11.
Teradata certification vantage is successful
software of its way. It is capable of handling 100 % of data with 100 % of the time.
By that, you can analyze any type of data. You can deploy this data anywhere in
this world. The Intellicloud is as a service that offers, it has measurability.
Information Intelligence across your company, on any type of infrastructure. Therefore,
you can work with Innovation and confidence without any type of bottlenecks.
