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.

Date and Time Standardization Principles

Currently, businesses focus on intelligent information systems supported by machine learning techniques, decision support systems, and prognosis management. Conventional principles are not suitable. The reference path over time needs to be covered. To cover the evolution over time, each state needs to be extended by the validity frames, represented by the date and time values, and even extended with multiple time zones and synchronization across regions. Unfortunately, there were no common standards and rules applicable in the first phases of development. Therefore, individual database system vendors decided to solve the problem in their own ways without creating a complex solution that would be generally applicable. Nevertheless, although individual systems do not apply the rules of international standard (ISO) standardization that were accepted later, we think it is very important to get a comprehensive overview of standardization, focusing...
