Interchange Database Operation
NOTE: In the following descriptions, we will use the following terms somewhat interchangeably:
key, code
Either one is a reference to the key for the database. In Interchange this is often the product code or SKU, which is the part number for the product.
Other key values may be used to generate relationships to other database tables.
It is required that the key be the first column of an ASCII source file for GDBM, Berkeley DB, or in-memory built-in database formats. It is also strongly
suggested that you keep that practice for SQL databases, since Interchange's import, export, and search facilities will work much better with that practice.
field, column
This is a column of the database. One of the columns is always the key -- Interchange prefers that the key be the first column. Field is an
interchangeable reference.
table, database
A table in the database. Because of the evolution of Interchange from a single-table database to an access method for an unlimited number of tables (and
databases, for that matter), we will sometimes refer to a table as a database. The only time database refers to something different is when describing that
concept as it relates to SQL -- where a database contains a series of tables. Interchange cannot create SQL databases, but given the proper
permissions it may drop and create tables within that database.
If necessary, Interchange reads the data to place in tables from standard ASCII-delimited files. All of these ASCII source files are kept in the products directory,
normally products in the catalog directory (where catalog.cfg is).
The ASCII files can have ^M (carriage return) characters if desired, but must have a newline character at the end of the line to work -- Mac users uploading
files must use ASCII mode, not binary mode!
Interchange's default ASCII delimiter is TAB.
IMPORTANT NOTE: The items must be separated by a single delimiter. The items are lined up for your reading convenience.
TAB
Fields separated by ^I characters. No whitespace should be at the beginning of the line.
code description price image
SH543 Men's fine cotton shirt 14.95 shirts.jpg
PIPE
Fields separated by | characters. No whitespace should be at the beginning of the line.
code|description|price|image
SH543|Men's fine cotton shirt|14.95|shirts.jpg
CSV
Fields enclosed in quotes, separated by commas. No whitespace should be at the beginning of the line.
"code","description","price","image"
"SH543","Men's fine cotton shirt","14.95","shirts.jpg"
NOTE: Using the default TAB delimiter is highly recommended if you are planning on searching the ASCII source file of the database. PIPE works fairly well, but
CSV delimiter schemes cause problems with searching.
