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.

Exploring NLS parameters and their impact

In order to be able to prepare a universal solution that can be deployed anywhere in the world, it is necessary to know the regional characteristics and formats and adapt the solution to your specific environment and customs. The aim of this section is to introduce you to individual NLS parameters and show you how to create a robust solution for various specific elements of date and time processing and representation.

We will look closely at parameters directly related to date and time processing. Toward the end of the chapter, we will see a summary of a few other parameters that are outside of the scope of this book.

We will start with NLS_DATE_FORMAT, followed by NLS_DATE_LANGUAGE, NLS_CALENDAR, and NLS_TERRITORY. By learning about them, you will be able to implement sophisticated solutions directly tailored to specific clients’ requirements in any region and on a global scale.
