How to size database ( Excel File Included)

How to find out the size of the datafile for a database consist of three tables with following specs:
1 year growth 5 Year growth
Table 1 400,000 record/year, 1 million record/5 year
Table 2 100, 000 record/year, 250, 000 records/5 year
Table 3 45/year, 60/5 year

Table1: Average Record length: 80
Table 2: Average Record length 100
Table3: Average Record length 35

I really need to understand this concept. Also I would like to understand the magic about min. extent, maxextents....

in short storage clause for the tables.

Thanks!!!

I really need help.

Thanks again!!!!

hi pandyar

It is difficult to measure the exact size of the datafile for the period of time.

We can calculate approx. datafile size by taking average record length multiply by average no.of records plus add 30% additional size for the particular table. Like wise we can proceed for other tables in the tablespace for the datafile.
