At no time does the user connecting to the database require direct property carried in their databases. Such concerns may include specifically the metadata (table structures and relationships, stored procedures and triggers) but may also include specific data carried questions on the Firebird lists along the lines of: “I want to…” “…protect my database design (table structures, stored procedures, triggers etc.) from all users of the database at a remote installation.

repeating characters is reduced to a control byte that determines the repeat count followed by the actual byte to be repeated. Where data cannot be compressed, the control byte indicates that "the next 'n' 'n' characters are to be output unchanged". The usage of a control byte is as follows: Positive n the next 'n' bytes are stored 'verbatim'. Negative n the next byte is repeated 'n' times, but stored decompression code needs to be able to know which bytes in the data are control bytes. This is done by making the first byte a control byte. Knowing this, the decompression code is easily able to convert
