The data resided on an Oracle 126.96.36.199.0 RDBMS running over the UnixWare Operating System. The data was uploaded on a daily basis onto the Oracle 7.x database residing on a Windows NT 4.0 system by running batch jobs. Remote database connectivity was accomplished by using SQL*NET V2 client software. This involved configuring the LISTENER.ORA and TNSNAMES.ORA files, starting the listener process and configuring the respective files required for remote database connection. This being a single-team member project was involved end to end into the design and development of the system. As part of ORACLE system administration and maintenance responsibilities was involved in installing the Oracle 7.3.x on Windows NT, creating users, creating roles, creating tablespaces , granting the roles to users, configuring the SQL*NET V2 files required for the remote database connectivity. The connection to remote Database was accomplish by using ODBC and SQL*NET V2. I was also responsible for generating reports using Crystal Reports 7.0 running on a Windows NT4.0 OS. This also involved creation of database links, views, elimination of duplicate records, deleting records after certain time frame, backing up data and automating the full process.
