Developing Robust Date and Time Oriented Applications in Oracle Cloud

By: Michal Kvet

Overview of this book

Proper date and time management is critical for the development and reliability of Oracle Databases and cloud environments, which are among the most rapidly expanding technologies today. This knowledge can be applied to cloud technology, on premises, application development, and integration to emphasize regional settings, UTC coordination, or different time zones. This practical book focuses on code snippets and discusses the existing functionalities and limitations, along with covering data migration to the cloud by emphasizing the importance of proper date and time management. This book helps you understand the historical background and evolution of ANSI standards. You’ll get to grips with data types, constructor principles, and existing functionalities, and focus on the limitations of regional parameters and time zones, which help in expanding business to other parts of the world. You’ll also explore SQL injection threats, temporal database architecture, using Flashback Technology to reconstruct valid database images from the past, time zone management, and UTC synchronization across regions. By the end of this book, you’ll be able to create and manage temporal systems, prevent SQL injection attacks, use existing functionalities and define your own robust solutions for date management, and apply time zone and region rules.

Timestamp Enhancements

One could say that life would be better and more secure if we had everything under control. In the past, businesses were entirely managed locally. Servers were placed in a local server room directly in the company, supervised by the system and database administrators. Employees knew administrators and technicians personally, mostly through filing complaints if something was not working as expected. Individual systems were locally managed and people were able to meet physically, with meetings coordinated by the locally defined time. Simply put, there was no need to deal with date and time synchronization.

With the globalization of business, multiple branch offices began to be created, opened, and managed, resulting in sharing systems and responsibilities. Customers started to spread across the world. This resulted in the necessity to coordinate activities by date and time. To ensure correctness and robustness, data needed to be managed not just locally in one...
