CASE STUDY FOR GOVERNMENT

+ Overview
Altibase
Altibase is provider of In-Memory
database solutions for real-time
access, analysis and distribution of
high volumes of data in mission-
critical environments.
EBS (Educational Broadcasting
System)
EBS is the sole, public television and
radio network in South Korea. With
national reach, EBS promotes
continuing, supplemental education for
all South Koreans. EBS, through its
online channel, EBSi, offers further
educational ubiquity through its e-
learning and online application systems.
Summary
Altibase helped EBS to handle more than 10 million subscribers with Single
Sign-On (SSO) features without delay.

+ Problems
EBS was focused on implementing a robust CRM platform that integrated
Single sign-on (SSO) LOGIN features, uninterrupted connectivity and
deeper educational solutions. With its lofty goals, EBS quickly realized
that current, multiple, data-driven systems could not meet its needs.
 EBS could not deploy the first step of its CRM, as its systems could not cope
with the demands of 10 million core subscribers utilizing the SSO property1.
 EBS’s initiatives required continuous up-time for 100,000 simultaneous, active
user sessions, doubling and thus, straining capacity.
 A critical, feature-rich application was “EBSApply,” an online admissions process
designed to help high-school seniors with college admittance. With the recent
memory of a similar, substandard launch in the private sector, fail-safe
preparation was top-of-mind.
 The new portal’s prerequisite was the elimination of Social Security Numbers
for LOGON. Although this satisfied EBS’ “Clean Site” requirements, it placed a
heavy burden on system processing.
 With just email, name and username, the demand on processing performance
increased by nearly 300%.
1) EBS-TV: 8 million subscribers, EBSi: 2 million subscribers

+ Solution
 ALTIBASE HDB In-Memory DBMS’ built-in High Availability (HA)
and Replication features allowed EBS to effortlessly handle the
increased capacity while also providing stability during peak
transaction times. Specifically, widespread system demands
during high-use periods (college application season), proceeded
glitch-free.

+ Results
 EBS has a robust CRM platform that provides a wealth of e-learning,
personalized web services and continuing education for all of South
Korea.
 EBS, without issue, handles its primary, 10 million subscribers with SSO
features.
 EBS processes 100,000 parallel sessions with ease, doubling its
capacity.
 Leveraging ATLIBASE HDB’s Hybrid functionality, all account
information, past and present, resides harmoniously for optimal use
either in-memory or on-disk.
 Readily available personal, proprietary and data-driven information
permits EBS to process vast college applications through its ‘EBSApply’
feature. This gives students invaluable utility, assisting them with the
growing demands of college admissions.

+ Technical Details
 EBS successfully implemented an Integrated ID Management System as part
of its new CRM platform by leveraging the key features of ALTIBASE HDB,
specifically in the areas of high-performance, high-availability, scalability and
flexibility.

 EBS had a new project initiative to build a CRM system infrastructure for subscribers of both the
primary EBS and EBSi web sites. EBS is the broadcaster’s flagship site with 8 million subscribers
and EBSi is the web site geared toward high school students with 2 million subscribers.
 One of the technical challenges of this project was to implement an Integrated Single-Sign-On
(SSO) Identification (ID) Management System for both web sites that could support and enhance
the performance for high number of concurrent users. The company also wanted to abandon the
use of associating a social security number with each account. The primary technical concerns
were system stability, performance and having the flexibility to maintain historical data.
 ALTIBASE HDB enabled EBS to architect an ultimate system that would satisfy all technical goals of
the project, in terms of performance, HA, storage flexibility and scalability.
 In this architecture, using the out of box replication feature, to maintain the integrated account
data, EBS deployed ALTIBASE HDB in the hybrid mode (in-memory + on-disk DBMS) on two
separate nodes with a dynamic HA and Scalability concept making use of both Active-Active and
Active-Standby configurations. During normal operation periods system would use the Active-
Standby configuration which provided EBS with the capacity and stability to handle typical
workloads (an average of 50,000 concurrent sessions).

Availability, Scalability and Flexibility

 The Active-Active configuration was the choice to handle high transaction
volumes for the peak period when a large number of students submitted their
undergraduate applications. The Active-Active configuration provided EBS
with the scalability to handle 100,000 concurrent sessions across two
participating active ALTIBASE HDB nodes.
 The hybrid mode allowed EBS to persist increasing number of historical data
for login and logout times, and web pages visited, in ALTIBASE HDB on-disk
DBMS with no constraints on the storage capacity.
 EBS’ Identification Management System is also benefited from the fact that
ALTIBASE HDB is standards-compliant and full-featured DBMS. With ALTIBASE
HDB, with no additional learning curve, EBS’s applications developers using
standard interfaces and programming languages such SQL92, JDBC and Java
implemented and deployed the new system within a two-month period.

Availability, Scalability and Flexibility
