| | 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. | | 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.

| | + | ====future==== |
| | + | It may be that Departments and Suppliers should be handled by the Topics tree, but this involves creating some infrastructure which is going to take some doing. (Specifically, we need to be able to assign named values – like "catkey" – to any topic, so that each Department topic and Supplier topic can refer to the proper catalog number.) |
| | | | |
| − | '''Note''': other contact data should probably be wiki-based. We'll have a namespace for vbz catalog data, probably "vbzcat:", and supplier information will be stored in pages named something like "vbzcat:lb.page", "vbzcat:lb.address", "vbzcat:lb.phone", and so on. (MediaWiki 1.5 will, if I understand right, allow regular non-template pages to be used as templates -- so we can have one page showing all the contact info together without having to enter it twice.)

| + | The [[/cat_depts]] table is seeming increasingly useless and an obstacle to good data design. Suppliers are prone to assigning items to different departments every year as their offerings change, and few or none of them use departments as part of their catalog key. In cases where they do, the amount of time saved by not having to key in 2-4 extra characters per catalog number simply isn't worth the extra maintenance and coding to make this work reliably. |

| |
| | | | |
| | + | The function of the cat_depts table can be replaced by the [[/brs_topics]] table (which should be renamed '''cat_topics'''). |
| | | | |
| | + | Once you start thinking about life after cat_depts, however, one has to ask whether [[/cat_supp]] should also be rolled into brs_topics. Obviously suppliers do, unlike departments, have some data significance: suppliers have catalogs, catalog groups, price functions, restock history... most of which data goes in other tables, not cat_supp itself, so it wouldn't be hard to use topics for suppliers too. |
| | | | |
| − | ==Future Changes==
| + | That would make it easier to allow the same item to be purchasable from multiple suppliers -- but how do you handle catalog numbers then? The same item can have different catalog numbers depending on where it was ordered from? Possibly this makes sense, but it still would cause trouble: each item still only has one item record, and that record needs a catalog number. Do you then move catalog numbers into a separate table that records item-to-supplier relationships? |
| − | ''This is probably obsolete, and may have been partially implemented. Review later.''
| |
| | | | |
| − | Shipping code should be tied to the item Option (i.e. no ID_ShipCode field in cat_items), which would include size and other variants (i.e. cat_itypes and cat_iopts will be combined). Each Supplier should have its own list of item types, to allow for different variation (e.g. LB tie-dye shirts of a given size weigh more than ZR shirts of the same size because they use thicker cloth). I'm using the schema as it is because converting the existing data will be a complicated task and we need to get this thing working ASAP, but I picture something like this in the near future:
| + | Is there any stopping point, short of "going all the way", that seems sensible? Can't we just eliminate departments for now, and worry about further enhancements later after mopping up all the code changes that that alone will require? That's probably a sensible compromise. |

| |
| − | **'''ID'''#@ - int(4)
| |
| − | **'''Name''' - text
| |
| − | **'''ID_Parent''' - int(4) -- cat_itypes.ID of parent type, if any
| |
| − | *'''cat_ioptns''' - catalog item options
| |
| − | **'''ID'''#@ - int(4)
| |
| − | **'''Key''' - string(8) -- Supplier.CatKey-Title.CatKey[-Key] = complete catalog number (Key can be blank)
| |
| − | **'''Descr''' - string(64) -- description of this option (e.g. "eXtra Large")
| |

| |
| − | **'''Descr''' - string(128) -- description of this option/type combination (e.g. "eXtra Large shortsleeve t-shirt")
| |
| − | We would then remove the ID_IType and ID_ShipType fields from cat_items; ID_IOpt would point to cat_itype_ioptns instead of cat_ioptns... or we could rename it ID_ITypeOptn, but that's... a bit ugly. I'll have to talk myself into it. Also, I think I used a scheme something like this in an earlier revision of the MS Access version of VbzCart and ended up changing it to what it is now; that may have been for a good reason, or it may have been because it seemed too unwieldy... I think I was generating a cat_itype_ioptns entry for ''every possible combination'' of IType and IOptn, and that doesn't make sense. You just need a tool to help manage them, and to copy existing sets for tweaking. It also didn't have an ID_Supplier key.
