Importance of storing information

For most of the organization the stored data is a most valuable corporate asset

as this data is used to:1. Achieve operational goals.

2. Run the business efficiently and effectively.

3. Helps in identifying the future direction and success of the company.

These day data is retained for very long period of time due to government regulations

and guidelines. How the data is managed and maintained varies enormously.

Today there is two additional objectives IT managers are trying to satisfy:1. To store vast quantities of data, for the lowest possible cost.

2. To meet the new regulatory requirements for data retention and protection.

Information Lifecycle Management

The management of complete lifecycle of information from its evolution to itsend is called as Information Lifecycle Management. Information Lifecycle

Management (ILM) is designed:

1. To understand how organization data evolves.

2. Determine how it grows.

3. Monitor how its usage change over time.

4. Decide how long it should survive.

ILM works with a combination of processes, policies, software and hardwareso that the appropriate technology can be used for each phase of the lifecycle

Of the data.

Why oracle database 11g for businessILM

The Oracle Database 11 g is capable of storing many different types of data i.e.Structured data(orders in an OLTP system or history of sales in a datawarehouse) as well as unstructured data(email, documents and images ) at asingle oracle database.

It means that it is much easier to manage, because the data is all in one place,instead of being stored using many different formats.

The Oracle database is the ideal platform to implement an ILM, because it hasa number of features:

Application Transparency; data classification is transparent.F ine-grained; managing data at individual row level.Low-Cost; uses low cost to reduce costs.Enforceable Compliance Policies; define and enforce policies.



7/19

Implementing ILM in 4 easy steps

B uilding an Information Management Lifecycle solution, using Oracle Database

11 g is quite straightforward, and it can be achieved by following these four

simple steps.

Step 1 - Define the Data Classes

Step 2 Create Storage Tiers for the Data Classes

Step 3 Create Data Access and Migration Policies

Step 4 Define and Enforce Compliance Policies



8/19

Step 1 - Define the Data ClassesIn order to make effective use of Information Lifecycle Management, the first

step is to look at all the data in your organization, what type of data is it and

determine:

Which data is important, where is it stored and what needs to be retained.

How this data flows within the organization.

What happens to this data over time and is it still needed.The degree of data availability and protection that is needed.

Data retention for legal and business requirements.

Once there is an understanding of how the data will be used, it can then be classified

by age or date, by product or privacy etc. Once the data has been classified, the

policies that will be applied to that data, will depend upon its class.



9/19

Continued .In order to treat the data classes differently, the data needs to be physically separated.In Oracle this can be achieved by using partitioning, and since partitions arecompletely transparent to the application, the data is physically separated, but theapplication still sees all of the orders.For example customers orders could be classified by the F inancial Quarters; Q1, Q2,Q3, Q4 and as Historical Orders and all will be residing in different partitions.



10/19

Step 2 Create Storage Tiers for theData Classes

Since Oracle Database 11 g , can take advantage of all the different storageoptions that are available, the next step is to establish the following storage

tiers:High Performance

Low CostOnline Archive

Offline Archive (optional)



11/19

Continued .STORAGE

TIERS

DATA STORED STORAGE DEVICES

Highperformance(Active data)

Important and frequentlyaccessed data would bestored

Utilize the smaller, faster disks on highperformance storage devices.

Low cost(Less Activedata)

Less frequently accesseddata is stored

Large capacity disks, which offer themaximum storage inexpensively areused.

Online Archive(Historicaldata)

Data that is never or hardlyaccessed would be stored

Extremely large amount of data incompressed form is stored online.

One of the benefits of implementing an ILM strategy is the cost savings that can result fromusing multiple tiered storage.Once the storage tiers have been defined, the data classes (partitions) identified in step one canbe assigned to the appropriate storage tiers.



12/19

Step 3 Create Data Access andMigration Policies

The next step is to specify who can access the data and the operations they

may perform and how to move the data during its lifetime.

Managing Access to DataUsing Oracle Database 11g, extremely effective methods for controlling what

authorized users of the database may see is to use database views or implementsecurity policies using virtual p rivate d atabase .

The benefit of this approach is:

It provides a secure and controlled environment for accessing the data.

Data cannot be overridden.

It can be implemented without requiring any application changes.

Read-only table spaces can be defined which ensures that the data cannot bechanged.



13/19

Continued .Migrate Data between Classes

During the lifecycle of the data it will be necessary to move it at various timesand this occurs for a variety of reasons, such as:

For performance, only a limited number of orders are held on the high performance

disks.

Data is no longer frequently accessed and is using valuable high performance

storage and needs to be moved to a low-cost storage device.

Legal requirements demand that the information is always available for a given

period of time, and it needs to be held safely at the lowest possible cost.

Within Oracle Database 11 g , there are a number of ways that data can be physicallymoved within the database to take advantage of the different storage tiers.



14/19

Step 4 Define and EnforceCompliance Policies

The fourth step in defining our ILM environment is the creation of compliancepolicies, which and when data is decentralized and fragmented, have to bedefined and enforced in every data location.When defining compliance policies there are five areas to consider:

RetentionIt will describe how the data is to be retained, for how long it must be kept andwhat happens at life end.

ImmutabilityIt is concerned with proving to an external party that data is complete and has not

been modified.

PrivacyIt is concerned for Access to data are strictly controlled using security policies.



15/19

Continued .

Auditing

It is capability to track all access and changes to data.

Expiration

Data may expire for business or regulatory reasons and its need to be removedfrom the database.

Using the Oracle Database to provide a central location for storing data, it is then very

easy to enforce compliance policies as they are all managed and enforced from one

central location.

Extra features of Oracle

Oracle ILM AssistantThe Oracle ILM Assistant is a GUI based tool for managing your ILM environment. It

provides:

The ability to create lifecycle definitions and show how to partition a table basedupon it.

Advises when it is time to move, archive or delete data.Illustrate the storage requirements and cost savings associated with moving thedata.

It can also display and query all the audit records and generate and compare digitalsignatures.

The Oracle ILM Assistant requires Oracle Database 9i or greater and that Oracle.



17/19

Continued .Online database archives

Today it is no longer necessary to archive data to tape, instead it can remain in the

database, or transferred to a central online archive database. There are a number of

benefits of keeping all of the data in a database for archival.

The most important is that the data will always be instantly available.

Development time needed to reload the extremely old past data into the databasefrom the tape archive will be expensive, and time-consuming.

Old data which is no longer required can be removed from online archive database

in very small time period by keeping the data in its own partition and then thepartitioned can be dropped accordingly.



18/19

ConclusionOracle Database 11g provides an ideal platform for implementing ILM because:

It s simple to use.It operates independent of any hardware.

It has proven fast performance as all information can be quickly retrieved.

Security features in the database ensure that data is secure from unauthorizedaccess.

Data is always transactionally consistent.It provides total flexibility.

We can define what should happen to data during its lifetime with appropriatetime.

Information Lifecycle Management enables us to understand our data, which is an

extremely valuable business asset, which must be managed properly, to ensure

business success and regulatory compliance. Using Oracle Database 11g, a

comprehensive ILM solution can be implemented for the lowest possible cost.
