Hi all. It's been a while.Since I don't contribute to ojb for some time
I'm looking for advice on this.
I'm trying to implement a user (U name it) control system that uses a
variable number of attributes. The database mapping for this will be
something like this :
ATTRIBUTE_LIST_ID - ATTRIBUTE_ID - ATTRIBUTE_TYPE - ATTRIBUTE_VALUE
Example
user1 : Leandro,male
user2 : diogo,??
user3 : ??,female
ATTRIBUTE_LIST_ID - ATTRIBUTE_ID - ATTRIBUTE_TYPE - ATTRIBUTE_VALUE
1 1 NAME LEANDRO
1 2 GENDER MALE
2 3 NAME DIOGO
3 4 GENDER FEMALE
Using one database row per user attribute gives me the necessart
flexibility to add/remove attributes and search for users based on the
attributes they have.
Is the any support on OJB to easilly persist and object like this :
AttributeList {
int listId; // glues attributes together
Map attributes; // each attribute has one attribute type and a value
}
Any helpful advice ?
