Entity relationship modelling, analysis class modelling and normalisation of data. They’re the three key approaches to analysing and modelling data, and they’re all covered on our course on Data Analysis.

You’ll also learn about approaches that reflect the business users’ needs and priorities, and gain an overview of the more mechanistic approach offered by normalisation. And finally we’ll explore the techniques used to validate data against stated requirements.

Presented to you by one of the expert training consultants pictured below, each member of our Data Analysis training team bring their substantial data analysis and data modelling experience to the programme.

За кого е курсът
Business analysts, project managers and solution developers who require a practical approach to analysing and modelling data. Data Analysis is also an Analytical Skills module on the BCS (ISEB) Advanced Diploma in Business Analysis.
