Hello.
I need some help. Assuming I have three tables/objects: forum, forum
category, forum group.
Forum - stores all topics posted by user. This object/table relates to other
tables including the aforementioned tables.
Forum category - stores the category whether science, technology, etc.
forumcategoryid is the primary key
Forum group - stores the group e.g. Adult, Teens, etc forumgroupid is the
primary key.
In my Forum data model:
//all necessary imports plus declarations
I'm storing forumcategoryid and forumgroupid in the table Forum so that I
can link Forum Category & Forum Group. When user post a new topic, the user
select the category and group from the dropdown box which are pulled from
Forum category and Forum Group. Do I need to do something like this in the
Forum entity class:
..
private ForumCategory forumCategory;
private ForumGroup forumGroup;
//getter and setters for these two; category & group
public Forum (list of all fields)
{
...
}
I'm all confused. When user post a topic, it needs to be in one of those
existing category and group. User is not allowed to create new category or
group. So embedding the forum category & group in Forum entity is pointless?
Another solution that I can think of, since the value of forumcategoryid and
forumgroupid are pulled from other table, i just might use these values and
save it into data store as part of Forum properties (so in the forum entity
I will have two additional fields named private String forumCategoryID,
private String forumGroupID).. Can someone help me or point me in right
direction? I'm a total beginner on this.
