Duration 4.375 Days 26.25 CPD hours This course is intended for The target audience for this course is all Oracle professionals. Among the specific groups for whom this course will be helpful are: Application designers and database developers Database administrators Web server administrators Overview This eTextbook begins with an explanation of the intent and usage of the PL/SQL programming language for database applications. Important reasons why one should incorporate PL/SQL modules within the application architecture right from the initial design and planning phase are presented. Next one learns how to begin building executable PL/SQL program units. One learns about each of the major segments of a working program and how these interact with each other during program execution, including the important error or exception handling capabilities of the language. The final section goes beyond the basics and begins to explore advanced topics that will be useful later in the Sideris Oracle PL/SQL developer textbook series. One learns techniques and features that allow modular and reusable programs to be developed, increasing productivity and maintainability of database applications. his eTextbook introduces one to Oracle database programming using the PL/SQL programming language. One will learn the syntax, structure and features of the language. This textbook will also lay the foundation for the entire Sideris Oracle PL/SQL programming series, allowing one to progress from introductory topics to advanced application design and programming and finally onto writing complex high-performance applications. his eTextbook introduces one to Oracle database programming using the PL/SQL programming language.

This course covers general allergies, food allergies and food intolerances and explains the differences between them. It covers the 14 allergens controlled by legislation along with food additives and how they can trigger allergic reactions. It takes a detailed look at the symptoms of food allergies and takes in the wider picture discussing the current theories of why rates are increasing. It then finishes off by covering practical steps that can be taken to reduce the risk from allergens and also what steps can be taken both internally and externally to monitor the control measures.

As well as informing you about the risks of working with asbestos, the course will deliver a lot more information about: Recognising asbestos, where it’s used, minimising the risks and the legislation about working with asbestos.

This awareness course covers the core concepts of the regulations and details the various roles that are required for a construction project along with the key documents that need to be produced. It starts with an introduction to CDM, then covers some of the parameters that need to be checked when a project is being planned. It finishes by detailing a number of example projects that illustrate how the regulations can be applied.

As well as informing you about the risks of working with asbestos, the course will deliver a lot more information about: Recognising asbestos, where it’s used, minimising the risks and the legislation about working with asbestos. This course is a variation on the Asbestos Awareness course that contains specific information for designers and architects.
