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.

Can you explain the terms database system, database, and database management system to me?
A database is a collection of organized data that can be easily accessed, managed, and updated. A database system is the software that manages and organizes the data within a database, allowing users to interact with the data in a structured manner. A database management system (DBMS) is the software that provides an interface for users to interact with the database system, allowing them to perform tasks such as querying, updating, and managing the data. In summary, a database is the collection of data, a database system is the software that manages the data, and a database management system is the software that allows users to interact with the data.

How does a Database Management System differ from database design and the use of a database?
A Database Management System (DBMS) is a software that provides an interface for users and applications to interact with the database. It manages the storage, retrieval, and organization of data in the database. On the other hand, database design involves the process of creating a blueprint for the structure and organization of the database, including defining tables, relationships, and constraints. The use of a database refers to the actual utilization of the database to store, retrieve, and manipulate data. In summary, the DBMS is the software that facilitates the management of the database, while database design is the process of creating the database structure, and the use of a database involves interacting with the database to store and retrieve data.

From when is a MySQL database connection automatically closed?
A MySQL database connection is automatically closed when the script or program that opened the connection finishes executing or when the connection is explicitly closed using the `close()` method in the programming language being used. It is important to properly close database connections to free up resources and prevent potential issues with the database server. Additionally, some programming languages and frameworks may have built-in mechanisms to automatically close database connections after a certain period of inactivity.

Spomenik Monument Database
The first ever spomenik guidebook, with over 75 examples alongside map references and information on why they exist and who built them. Spomenik’ the Serbo-Croat/Slovenian word for ‘monument’ – refers to a series of memorials built in Tito’s Republic of Yugoslavia from the 1960s-1990s, marking the horror of the occupation and the defeat of Axis forces during World War II.Hundreds were built across the country, from coastal resorts to remote mountains.Through these imaginative forms of concrete and steel, a classless, forward–looking, socialist society, free of ethnic tensions, was envisaged. Instead of looking to the ideologically aligned Soviet Union for artistic inspiration, Tito turned to the west and works of abstract expressionism and minimalism.As a result, Yugoslavia was able to develop its own distinct identity through these brutal monuments, which were used as political tools to articulate Tito’s personal vision of a new tomorrow.Today, following the breakup of the country and the subsequent Yugoslav Wars of the 1990s, some have been destroyed or abandoned.Many have suffered the consequences of ethnic tensions – once viewed as symbols of hope they are now the focus of resentment and anger. This book brings together the largest collection of spomeniks published to date. Each has been extensively photographed and researched by the author, to make this book the most comprehensive survey of this obscure and fascinating architectural phenomenon. A fold-out map on the reverse of the dust jacket shows the exact location of each spomenik using GPS coordinates.

How can an SQL database be properly normalized for database experts?
Database experts can properly normalize an SQL database by following the principles of database normalization. This involves organizing the data into multiple related tables to reduce redundancy and improve data integrity. The process typically involves breaking down large tables into smaller, more manageable ones, and establishing relationships between them using foreign keys. By adhering to the normalization rules (such as eliminating repeating groups and ensuring each table serves a single purpose), database experts can create a well-structured and efficient database design. Regularly reviewing and adjusting the database schema based on changing requirements can also help maintain proper normalization.
