| [[Technology]]: [[VbzCart]]
| | ==About== |
| | [[VbzCart]] is {{l/htyp|free/open-source}} software for running an {{l/htyp|online retail}} operation. |
|
| |
|
| Having evaluated [[osCommerce]] and found that, although it had many features I would like to have on vbz.net, it also lacked some crucial features currently needed (many of which are provided by the existing shopping cart system, and some of which would be needed in order to effectively manage porting the data from the existing system).
| | * '''[[/install]]''' has deployment instructions |
| | * '''[[/status]]''' critical pieces still need to be (re)written, though most of it is working well (2017-06-25) |
| | ==Purpose== |
| | The immediate purpose is to handle the more data-intensive aspects of managing a small online retail operation that offers a wide variety of products in a wide variety of choices. This [[/pieces|includes]] tracking orders, tracking packages sent to fill those orders, stock and inventory, which items need to be reordered from suppliers, what is currently expected from suppliers, what suppliers have sent in the past, etc. |
|
| |
|
| So I'm writing a new system, in PHP, based on the data design of the existing VBZ cart system and adding new pieces as needed.
| | Once that is up and running, I'll begin work on additional functionality: |
| | | * "marketplace" ability -- 3rd parties can sell their items through the same site, and VbzCart will provide most of the same functionality to them |
| I will be taking notes on this page and gradually refining them into something resembling documentation, with the ultimate goal of producing a system which could be released under an [[htwiki:FOSS|open source]] license.
| | * distributed catalog search and other {{l/igov|federated retail}} functionality |

| ===Administration===
| | | |
| ====Main data tables====
| | * [[/ui]]: help pages |
| *'''admin_users''' -- users with access to the admin system
| | * [[/pieces]]: features and concepts |
| **'''ID'''#@ - int(4)
| | * [[/coding]]: technical documentation |
| **'''Name''' - varchar(32)
| | | |
| **'''Email''' - varchar(128)
| | * [[/history]]: how we got here |
| *'''admin_groups''' -- each group has a role to play, and each role requires a particular set of privileges
| | * [[/archive]]: obsolete pages |

| | * [[/meta]]: how to document |
| **'''Name''' - varchar(32)
| | |} |
| **'''Descr''' - text -- text describing the purpose of this group
| |
| *'''admin_privs''' -- particular privileges; meaning is defined in code | |
| **'''ID'''#@ - int(4)
| |
| **'''Name''' - varchar(32)

| **'''Descr''' - text -- text describing this permission
| |
| ====Collection/link tables==== | |
| *'''admin_user_groups''' -- users in each group / groups to which each user belongs
| |
| **'''ID_User'''# - int(4)
| |
| **'''ID_Group'''# - int(4)
| |
| *'''admin_group_privs''' -- privileges each group has / groups having a particular privilege | |
| **'''ID_Group'''# - int(4) | |
| **'''ID_Priv'''# - int(4)
| |
| ===Catalog===
| |
| | |
| A "Title" is a group of items with a common description, e.g. different sizes or styles of a shirt, different media (CD, cassette) for an audio recording.
| |
| | |
| In the previous version of the cart software, we had to have items of somewhat different appearance (e.g. longsleeve and shortsleeve shirts) sharing a single title, so as to remove the necessity to ''always'' have pictures for each. In this version, a title can point to another title for its picture, thus keeping it clear whether the picture is truly representative or just an approximation.
| |
| | |
| *'''cat_titles''' -- catalog titles | |
| **'''ID'''#@ - int(4) (autonumber)
| |
| **'''ID_Supplier''' - int(4) -- cat_suppliers.ID
| |
| **'''ID_Similar''' - int(4) -- cat_titles.ID of a similar title whose image can be used, if this title lacks one
| |
| **'''Name''' - varchar(128) -- name of title, usually according to supplier (not strict)
| |
| **'''CatKey''' - varchar(32) -- must be unique within supplier
| |
| **'''Descr''' - text -- descriptive text (also may be included in search)
| |
| | |
| *'''cat_items''' -- catalog items
| |
| **'''ID'''#@ - int(4) (autonumber)
| |
| **'''CatNum''' - varchar(32) -- catalog number: must be unique, but may change
| |
| **'''ID_Title''' - int(4) -- cat_titles.ID
| |
| **'''ID_IType''' - int(4) -- type of item | |
| **'''ID_IOpt''' - int(4) -- item option (usually size)
| |
| **'''ID_ShipCode''' - int(4) -- shipping cost code
| |
| **'''Price''' - currency -- price to customer
| |
| | |
| ===Shopping===
| |
| | |
| The items a customer wants to order are saved in a cart. The cart also saves session information, e.g. customer's IP/domain, but not the customer's shipping or payment data. Later on, we'll allow customers to make changes to carts after the cart has already been assigned to an order, so will need session info stored separately, which is why it's in a separate table.
