A multidrop bus (MDB) is a computer bus able to connect three or more devices. A process of arbitration determines which device sends information at any point. The other devices listen for the data they are intended to receive.
MDB originated as a proprietary bus used by CoinCo for their coin-acceptors in the late 1980s and was deployed in high volume in vending machines for Coca-Cola.Coke forced CoinCo to open-source it in 1992 to increase competition, and NAMA released the first version of the standard in 1995, allowing other vendors to compete for the coin-acceptor portion of the vending machines (CoinCo and Mars ...
The MDB tools project is an open source effort to create a set of software libraries and utilities to manipulate files in the proprietary JET 3, 4 and 5 database formats (used by Microsoft Access.). Version 0.7 was released in June 2012.
Jet, being part of a relational database management system (RDBMS), allows the manipulation of relational databases. [1] It offers a single interface that other software can use to access Microsoft databases and provides support for security, referential integrity, transaction processing, indexing, record and page locking, and data replication.

The provision of a unique append-write mode (MDB_APPEND) [1] is implemented by allowing the new record to be added directly to the end of the B+ tree. This reduces the number of reads and writes page operations, resulting in greatly-increased performance but requiring the programmer to ensure keys are already in sorted order when storing in the DB.
