Assessment of the needs of the application

Hello

I'm new to the estimation of the size of the application needs. I'm looking to hosters APEX and wonder which of their service plans to choose and if a provider that uses 10g express will meet my needs. For example, I want to know if I pass a plan with 50MG of space oracle in a few months or a few years, and if I should start by a provider with edition complete 10 gr 2 rather than Express.

I have a data capture application when the main table that will grow has 30 rows that will capture the text. There will be probably 1500 records created each week. I will need to keep 2 years of data available at all times.

Any suggestions on how to estimate the amount of space db, I'll need in 6 months, 12 months, etc.? It is more difficult than the creation of the actual application.

Thank you
Matt

Hmm,
It seems not so hard once that break it down you.
2 years of data = 2 * 52 weeks = 104 weeks of data
1500 documents per week * 102 weeks = 153000 documents you will need to have given to any point in time

Create your schema on its own tablespace and take note of its size. Then to adapt this code to your needs (add columns, change data types, etc.):

DECLARE
  x VARCHAR2( 255 );
BEGIN
  x := 'String that resembles you actual data';
  FOR i IN 1..153000 LOOP
    INSERT INTO T1 ( ID, COL1 ) VALUES ( i, x );
  END LOOP;
END;

Then, you'll have an estimate of the amount of space you need. You should, of course, account index.
Furthermore, I believe that this code could REALLY use bind variables.
Kind regards
