SQL (Structured Query Language) is a powerful domain-specific language designed for managing and manipulating relational databases. It allows users to define, query, and manipulate data in a relational database management system (RDBMS). SQL consists of various commands, such as SELECT, INSERT, UPDATE, and DELETE, enabling users to interact with databases efficiently.
PL/SQL (Procedural Language/SQL) is an extension of SQL developed by Oracle. It integrates procedural constructs with SQL, allowing for the creation of stored procedures, functions, and triggers. PL/SQL enhances the capabilities of SQL by providing procedural programming features like loops, conditional statements, and exception handling. This enables the development of more complex and dynamic database applications.
DBMS (Database Management System) is a software suite that facilitates the creation, management, and interaction with databases. It provides an interface for users and applications to interact with the database, ensuring data integrity, security, and efficient data retrieval. Popular relational database management systems include Oracle Database, MySQL, Microsoft SQL Server, and PostgreSQL.
In summary, SQL is the language used to communicate with databases, PL/SQL extends SQL by adding procedural programming capabilities, and a DBMS is the overarching software that manages databases, ensuring optimal organization and retrieval of data.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
