I was thinking of implementing a file based persistent store in Java. I can write the contents of the Objects to a file on the disk. I can dump 100 objects (e.g., for 100 employees) to a file. However how do I read one of the object (for a particular employee) back?
For example if I want to change the data for an object, how can I retrieve the object and replace it in the file.
I hope my question makes sense. In terms of databse terms, Create is fine, but how do I perform Read/Update/Delete?
Couple of options that comes to my mind are:
- create a different file for each object
- retrieve the data for all objects, deserialize them and subsequently persist them again after performing the relevant operations
But both of them are not efficient and have drawbacks.
I hope my question makes sense. Will be thankful for any suggestions/pointers.

I don't feel so bad for myself, But for others who I feel I had provided a forum to say stuff and you took that all away in one swoop. Why Ulf, Why not?

No, I didn't. I might have seen the first one or two starring Roger Moore (although I don't remember), but nothing after that. All of them since might have been great movies for all I know, but for me, if it doesn't have Sean Connery, it ain't James Bond.

Nothing wrong with you at all. I read the first two and it didn't take me long to notice that the story of Harry Potter was also the story of Luke Skywalker and Frodo Baggins, in a different setting.
