Referral Page
- A
webpage which links to your
website and sends traffic. The
URL
will appear in your website's
server logs, or in The Counter's analysis of your traffic. A good
referral page can be worth more than a good
search engine ranking, since it is likely to last longer.
Relational Database (RDBMS)
- A
database based on the relational model developed by E.F. Codd. A
relational database allows the definition of
data structures, storage and retrieval operations and integrity
constraints. In such a database the data and relations between them are
organised in tables. A table is a collection of rows or records and each row
in a table contains the same fields. Certain fields may be designated as
keys, which means that searches for specific values of that field will use
indexing to speed them up.
Where fields in two different tables take values from the same set, a join
operation can be performed to select related records in the two tables by
matching values in those fields. Often, but not always, the fields will have
the same name in both tables. For example, an "orders" table might contain (customer_id,
product_code) pairs and a "products" table might contain (product_code,
price) pairs so to calculate a given customer's bill you would sum the
prices of all products ordered by that customer by joining on the
product-code fields of the two tables. This can be extended to joining
multiple tables on multiple fields. Because these relationships are only
specified at retreival time, relational databases are classed as dynamic
database management system.
The first commercial RDBMS was the Multics Relational Data Store, first sold
in 1978.
INGRES, Oracle, Sybase, Inc., Microsoft Access, and Microsoft SQL Server are
well-known database products and companies. Others include PostgreSQL,
SQL/DS, and RDB.

RSS (Rich Site Summary)
- A family of document types (generally based on RDF) for listing updates
to a site. RSS documents (generally called "RSS feeds") are readable with
RSS readers (generally called "aggregators") like BottomFeeder, although, in
2003, it is anticipated that aggregator functions will be incorporated into
web
browsers and/or NNTP newsreaders.
