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.

Summary

The topics covered in this chapter are particularly important in the context of business expansion, in which it is necessary to synchronize events across multiple regions and, in general, the entire world. In this chapter, you learned about data types and synchronization techniques. You also learned about the complexity of the local and database date and time, focusing on time zone shift.

Additionally, in this chapter, the TIMESTAMP data type extensions were highlighted, preceded by the FROM_TZ and NEW_TIME functions. Time zone reflection and shift processing are critical. You probably wouldn’t like to arrive at an online meeting an hour after it ended, right? So, now, you are prepared to trade worldwide and offer your solutions anywhere, as well as organize webinars and meetings with participants from any region.

In this chapter, session and database date and time were discussed, dealing with the sysdate and current_date differences, as well as systimestamp and...
