      abstract = {Database technology is an important subject in Computer  Science. Every large company and nation needs a database to  store information. The technology has evolved from file  systems in the 60, to Hierarchical and Network databases in  the 70's, to relational databases in the 80's,  object-oriented databases in the 90's, and to XML documents  and NoSQL today. As a result, there is a need to reengineer  and update old databases into new databases. This book  presents solutions for this task. In this fourth edition,  Chapter 9 - Heterogeneous Database Connectivity (HDBC)  offers a database gateway platform for companies to  communicate with each other not only with their data, but  also via their database. The ability of sharing a database  can contribute to the applications of Big Data and surveys  for decision support systems. The HDBC gateway solution  collects input from the database, transfers the data into  its middleware storage, converts it into a common data  format such as XML documents, and then distributes them to  the users. HDBC transforms the common data into the target  database to meet the user's requirements, acting like a  voltage transformer hub. The voltage transformer converts  the voltage to a voltage required by the users. Similarly,  HDBC transforms the database to the target database  required by the users. This book covers reengineering for  data conversion, integration for combining databases and  merging databases and expert system rules, normalization  for eliminating duplicate data from the database, and above  all, HDBC connects all legacy databases to one target  database for the users. The authors provide a forum for  readers to ask questions and the answers are given by the  authors and the other readers on the Internet.},
