About Oracle NoSQL Database Oracle NoSQL Database is a robust solution offering a blend of SQL-like interfaces for working with NoSQL data models. This database system enables developers to handle various data types without impedance mismatch issues, including flat relational data, hierarchical typed data, and schema-less JSON data. Impedance mismatch occurs when differences between the database and the programming language models create data handling challenges. Still, Oracle NoSQL eliminates this by providing a seamless experience across multiple data structures. Oracle…

Welcome to the lesson of our “SQL Interview Preparation Series: Mastering Questions and Answers Quickly!” Throughout this series, we aim to assist you in getting ready, for SQL interviews by delving into different topics. Today we’re delving into the core variances between SQL and NoSQL databases, a subject for any data focused job interview. Understanding SQL and NoSQL Relational databases, commonly referred to as SQL databases, are crafted to handle data. They adhere to a predefined schema, which makes them…

Polymorphism, a fundamental concept in object-oriented programming, allows objects of different types to be treated as instances of a common superclass. This flexibility is essential for creating systems that can be easily extended and maintained. While traditional SQL databases in combination with Jakarta Persistence (JPA) can handle polymorphic data, NoSQL databases offer distinct advantages. Unlike SQL databases, which require strict schema definitions, NoSQL databases take a schema-less approach, inherently supporting dynamic and flexible data structures. This flexibility becomes especially appealing…

In most financial firms, online transaction processing (OLTP) often relies on static or infrequently updated data, also called reference data. Reference data sources don’t always require ACID transaction capabilities, rather need support for fast read queries often based on simple data access patterns, and event-driven architecture to ensure the target systems remain up-to-date. NoSQL databases emerge as ideal candidates to meet these requirements, and cloud platforms such as AWS offer managed and highly resilient data ecosystems. In this article, I…

In this hands-on lab from ScyllaDB University, you will learn how to use the ScyllaDB CDC source connector to push the row-level changes events in the tables of a ScyllaDB cluster to a Kafka server. What Is ScyllaDB CDC? To recap, Change Data Capture (CDC) is a feature that allows you to not only query the current state of a database’s table but also query the history of all changes made to the table. CDC is production-ready (GA) starting from…
