During my tenure in the bank, I have carried out many advanced and challnging jobs. It was really a great and unforgatable experience in the bank. All my colleages and my immediate boss were really very good and very cooperative.

There is no thump rule for calculating SGA. In fact, you shouldn't go for any.
There are couple of good mealink notes available on metalink site.
Note:1008866.6 - How to determine SGA from (7-10).
It also depends on your application and db type. i.e. OLTP database or DATAWAREHOUE DB.
In my opinion, you should start with the an optimal value and increase gradually upon demand.
From 9i onwards, oracle also help in dynamic sga, where you can set the upperlimit memory size for the sga, using parameter sga_max_size.
In 10g, setting a single sga parameter, sga_target, Orale automatically calculates the optimal value for db_cache_size & shared_pool. It increase and decreases the values upon demand.
