So your concept is to move the ancient concept of a codebook into a
database? It is ECB with encryption replaced by a lookup.

The overall security is as strong as what I will call the chaining mode
within and between the messages. By this I mean that is "orcdriffle" always
translates to "telephone" the construct will leak and quickly fall apart.
You need some method of convolving the database even within the same
message. I would actually suggest having a look at RC4 to create a double
lookup method, it should be simple to create an effective chaining mode from
ther, but the security will be suspect. For stronger security you'll want to
look at the designs of strong stream ciphers.
