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.

Temporal system requirements

The requirements for temporal systems were first summarized in the book Managing Time in Relational Databases by Tom Johnston and Randall Weis. They presented the first two aspects – usability and performance. Based on our own research, we’ll extend the definition to the rest of the aspects. The main reason for the extension is to ensure complexity and describe in detail the temporal approach used:

  • Usability: This focuses on the ease of use of methods for users. The aim is to provide a robust and easy-to-use solution, regardless of whether we access currently valid records, historical data (images of objects that were valid in the past), or records that will become valid in the future, but information about these states is already stored in the database. This aspect also focuses on the possibility to monitor changes, perform statistical evaluation, and create a platform by providing input data for decision-making.
  • Performance:...
