Data model design: what and how are you going to record data in your database? Although the term data model is commonly used by software developers to describe data structure in computational coding, the conceptual approach to data modelling stresses the importance of design, planification, and anticipating needs or probable issues to solve. The data model is an abstraction that describes how data is organised in your database. Designing the structure of our data system requires understanding the type of objects you are going to describe and how are they related to each other. Addressing the data model design consciously as a first stage will save you time and effort. We strongly invite you to illustrate the data structure before starting to record or migrate your data. The data model is conditioned by: analysis needs, type of data, volume of data, frequency of use and updates, relationships between data and the type of tool used to store and process data, among others. 6
