2. • A database is an organized collection of
data.
• Databases are created to operate large
quantities of information by inputting,
storing, retrieving, and managing that
information.
• Databases are set up so that one set of
software programs provides all users with
access to all the data.
3. • A Database Management System (DBMS) is a suite of
computer software providing the interface between users and
a database or databases.
• Database management systems (DBMSs) are specially
designed applications that interact with the user, other
applications, and the database itself to capture and analyze
data.

resulting in changes to SQL execution plans and performance
characteristics
• Examples of common system changes for which you can use SQL
Performance Analyzer
Database upgrade
Configuration changes to the operating system, hardware, or
database
Database initialization parameter changes
Schema changes

17. HISTORY
• British telecommunications is one of the world’s leading
telecommunications companies.
• BT has almost 93,000 employees serving customers in more
than 170 countries worldwide.
• In UK, the company provides broadband products and
service to almost six million customers, as well as fixed-line,
mobile and TV offerings to millions more consumers.
18. • Worldwide, BT sells wholesale products and services to
leading communications providers and supplies managed

services sold to BT customers worldwide, retail and wholesale.
• Its staff includes over 13,000 IT professionals in more than 20
countries.
19. PROBLEMS
• BT had a large and growing database infrastructure that
Surren Partabh, CTO Core Technologies of BT Operate
characterized as “rapidly falling into legacy due to the pace of
technology innovation we see in the world.”
• Company’s large range of products and services inevitably led
to a sprawling set of application and operational silos
dependent on thousands of databases.
• Keeping up with upgrades and patches was an enormous job.
• Day-to-day management was difficult.
20. • Difficult to keep up with customer expectations and
competitive demands.
• Application deployment was slow and expensive.
• Ever-growing complexity of the company’s database
infrastructure was raising operational costs and staffing
requirements, with IT workload soaring.
• Company had DBA’s begging to retire, but company
couldn’t afford to let them go.
21. SOLUTION:
Database Consolidation onto a Private Cloud with Oracle Database 11g
• The company decided to build a DaaS platform using the
features and options of Oracle Database 11g to create a
private cloud.
• Oracle Real Application Clusters enabled BT to standardize
their deployment model, reducing the deployment time for a
fully-tested, highly available database from two to three weeks
down to only 19 minutes.
22. • Other Oracle database 11g features and options such as
Clusterware, Automatic Storage Management(ASM),
Advanced Compression and Partitioning also played an
important role in BT’s private cloud consolidation
• BT moved the applications on legacy systems over to the
Oracle Database 11g private cloud.
23. RESULTS
• Consolidation onto a standard Oracle Database 11g cloud
has made management so much easier that they are
managing 30% more databases with 20% fewer personnel
hours.
• It improved business agility.
• Improved customer service.
• Reduced cost.

31. Dena Bank
History
• Dena Bank offers personal and corporate banking
services to around seven million individuals and
businesses across India.
• Dena Bank operates around 1,500 automatic teller
machines (ATMs), which are a crucial part of the
service it provides to customers throughout India
32. Dena Bank
Requirements
• Deploy new server and storage infrastructure to
improve the performance of core banking and ATM
applications to enhance customer service
• Provide automatic failover capabilities that ensure
core applications continue running in the event of a
server failure or major disaster
• Reduce IT infrastructure costs and gain a quick
return on investment
34. Dena Bank
Solution
• Engaged Oracle Advanced Customer Support
Services, Oracle Consulting, and Oracle Partner
HCL Infosystems to help improve customer service
and support future growth
• Enhanced customer service by increasing the speed
of ATM transactions by 80% and reduced the
number of declined transactions from 10% to less
than 1%
• Provided a huge database and storage infrastructure
35. Dena Bank
• Supported ATM transaction and customer growth—
and enhanced system
• Decreased the total cost of ownership
• Ensured core banking and ATM applications are
always available by providing automatic failover
capabilities, which shift processing load from one
server to another in the event of a system failure
• Stored database and application data more
effectively and at the lowest possible cost by
deploying a scalable storage area network
37. ORACLE DATABASES: CONCLUSION
• Oracle databases are all about robustness, power and exceptional data
maintaining capabilities.
• Security and performance are the highlight of Oracle databases.
• However, Oracle databases are feasible only when you need large
databases. With the amount of work and hardware needed to deploy, it is
not ideal for small or mid-sized companies where other feasible options
such as MySQL or Microsoft SQL can be more cost effective with similar
functionality.
• Oracle databases are notorious for their complexity and therefore not the
ideal choice when either the workforce isn’t highly technical or you want an
easy-to-use database with basic features.
