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 migration techniques

The critical parts of information technology are data management, data access, and an internal repository. Without data, no relevant decisions can be made. When we shift systems to the cloud, it is inevitable that we need to transfer data as well. However, how do we do that if the data source is large? This section deals with the various techniques for data migration, so let’s dive right in!

OCI Data Transfer Service

Databases can be really extensive, even in petabytes. Moving repositories from data centers to clouds can take weeks or even months. Moving data over the public internet can be expensive, maybe even impossible due to an unreliable network, low speed, or security aspects. OCI Data Transfer Service offers you the option to order the transfer, which is then managed directly by Oracle. It is operated by the Oracle Cloud console or the Command-Line Interface (CLI). The data to be imported is shipped to Oracle, commonly on encrypted...
