EO Extension question?

Question

Hello,
I am pretty new to the OA Framework extensions, and have a task of extending one of the self service pages on eBusiness suite. Could anybody please suggest a good approach for this one.
Requirement is to extend a self-service page to add more user enterable fields on the page. (** These fields are not on the base table EO/VO**)
This is what I have done so far:
I have altered the base table to add new attribute columns (attribute1 - attribute15) and attribute_category.
These attribute columns (attribute1-attribute15 and attribute_category) need to be added to the EO and VO
Since, this is a custom DFF, can I just personalize the page to add these attributes as DFF on the page?
Where to put the logic to insert data into these additional attribute columns?Could anyone please list me the steps to do this EO extension?
Thanks for all the help.

Thanks Tapash,
Based on your comments, I have created a custom table to hold the additional information with a key to join with the seeded table.
Could you please verify if these detailed step is OK? ** I am pretty new to OA Framework extensions and JDeveloper ** (I have done a VO extension before but long time back though!) ** So my questions might be basic/silly **
Using the Jdeveloper,
1. Create a OA workspace and OA Project.
2. Create a new OA business component. (Create a new EO and VO for the custom table) -- Should these extend the original EO and VO ?
3. Import all the related server.xml
4. Where should the code be? to insert the additional information (EOImpl?)
5. Substitutie
6. Using Personalization, create new items on the page ??? (Or should the Page be customized using the JDeveloper?)
And I would appreciate if you could share code snippet to insert into table.
Thanks for you help.
