Information Systems Reengineering, Integration and Normalization : Heterogeneous Database Connectivity
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’s, 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.

How can one transition web development from a fake database to a real database using Vue?
To transition web development from a fake database to a real database using Vue, you can start by setting up a backend server that connects to your real database. This server can handle requests from your Vue application and interact with the database to retrieve or store data. You will need to update your Vue components to make API calls to the backend server instead of directly manipulating the fake database. By following this approach, you can seamlessly transition from using a fake database to a real database in your Vue application.

Why doesn't PHP have access to the database?
PHP doesn't have direct access to the database because it is a server-side scripting language, and allowing direct access to the database from the client-side could pose security risks. Instead, PHP interacts with the database through database management systems like MySQL, PostgreSQL, or SQLite using specific functions and extensions. This approach helps to maintain a secure connection between the server and the database while allowing PHP to perform database operations efficiently.
