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.
