IBM WebSphere Commerce 中的关于catalog 的表设计

在学习IBM WebSphere Commerce的时候，看到关于catalog的表设计，觉得非常灵活强大。
一个store可以对应多个目录，一个目录可以属于多个store，不同子目录在不同store中可以显示，也可以不显示。
Commerce是做大型B2B,B2C网站，基本概念包括：
store  -- 具体的一个网站，实际网站下可以有多个子网站，参考连锁店之类的经营模式。
catalog -- store的主目录
catalog group -- 分组，子目录
catalog entry -- 一类产品，或一个产品，或一个产品包。

one store can have multiple catalogs, on catalog can belong to multiple stores.

TABLES
1. catalog(CATALOG)
PK:catalog_id
(identifier + member_id) 组成index

next: catalog catalog group relation objects

2. catalogdsc(CATALOGDSC)
if catalog without catalogdsc , maybe cannot be viewed in browser, but can ve viewed in accelerator.
for catalogdsc has language_id, so it contains language-dependent imformation.

3. catalog group(CATGROUP)
Used to organize a catalog and help the shopper navigate to the products.

catalog catalog group relation object - links the foremost catalog groups to a catalog
catalog group relation object - links child category groups with their parent group
catalog group catalog entry relation object - links catalog entries with their parent catalog group

4. catalog group attribute(CATGRPATTR)
catagrpattr_id(PK),
language_id(PK),
catgroup_id,
...

It present a view that the shopper uses to compare similar catalog groups.
It includes a sequence column to be used to order the attribute names.

5. Catalog group description(CATGRPDESC)
It contains language-dependent information and an image suitable for viewing.
and a required column: published is important!

thumbnail for gif  -- path?
fullimage for gif  -- path?

6. Catalog catalog group relation(CATTOGRP)
Used catalog_id to find the root categories.
catalog_id(PK),
catgroup_id(PK),
sequence,
catalog_id_link
...
here there is a catalog_id_link bigInt nullable, what purpose?

7. Catalog group relation(CATGRPREL)
relation about group to group
catgroup_id_parent(PK)
catgroup_id_child(PK)
catalog_id(PK)
rule
sequence
catalog_id_link
...
here there is a catalog_id_link bigInt nullable, what purpose?

8. Catalog entry(CATENTRY)
four types:
Item - a tangible unit of merchandise that can be purchased and be shipped.
Product - represents a collection of items that have identical attributes but can be distinguished by their attribute values.
Package - is a collection of items that must be purchased as a single atomic unit, even if its items can be ordered separately.
Bundle - is a collection of items that can be added to the shopping cart with a single selection while its items can be ordered separately.

catentry_id(PK)
member_id
itemspc_id
catenttype_id
mfpartnumber
mfname
markfordelete

baseitem_id
...

9. Catalog entry attribute(CATENTATTR)
contains descriptive attributes for catalog entries.
catentattr_id(PK)
language_id
catentry_id
name
value
....

10. Catalog entry description(CATENTDESC)
A catalog entry description object contains language-dependent information and an image suitable for viewing by a shopper.
