    Unanswered: post gres

    hi

    Im using post gres for my database.Now I have got a doubt .Im using three tables with 3 entities x,y,z these have attributes.So this is ok. Now I need to get another table say a where x,y,z are attributes. But these are not static they may be dynamic. That is one row of table a may contain all the three attributes or two or one. Now how to model this situation.


    Im thinking to go for linked list .But I need this data to be persisitent
    Any help

    bye

    questions

    i don't understand exactly your needs

    you have 3 tables x,y,z ...ok

    1 table where x,y,z are attributes


    "dynamic" what do you mean with this?

    one row containing all 3 attributes or 2 or 1

    be more specific please?

    my understanding
    1 table
    x text
    y text
    z text

    you can have data in x or y or z
    or am I wrong?

    I don't understand the problem?
