The Client
OSS for TN region has several limitations relating to its database such as:
uMaintaining application is tedious as one needs to know quite older version
of database and which doesn’t support some of the basic operations like sub-
queries, stored functions etc. and thus in order to maintain the application,
programmer needs to apply some of the workarounds which makes
application more fragile.
uCarrying out enhancements and tweaks to application are more effort
intensive and error prone as MySQL 3.x has lot of limitation in various SQL
syntax like Stored Procedures, sub-query etc. support is not there in 3.x
version.
u90% of reports can not be generated or take a very long time, making
application unusable at times. Due to erroneous data model and slow query
retrieval engine of MySQL 3.x, this issue is being faced right now.
uWith the growing number of subscriptions, scalability of OSS is big
roadblock as data retrieval engine in MySQL 3.x is quite primitive and thus
with larger set of data, retrieval would become even slower.
uAs current data model is not optimized and tuned, Analytical
reporting/Dashboard not possible with current database structure. Oracle
has many inbuilt features like Materialized views etc. to take care of
analytical needs of application.
uIn current application creation of data dump is not efficient and thus data
requirements of legal department are not easy to fulfil.
uUser Interface design not intuitive; options are cluttered on screen, no
separate “tabs” to operate on logically grouped options.

Operations Support System (OSS) is
buckling down and is not able to scale up

database - MySQL. In order to meet the
growing needs, as a first step, airtel
decided to migrate the database of OSS
from MySQL 3.x to Oracle 10g, a leading
database for enterprise applications. The
