In today’s data-centric business environment, an organization’s information stores are one of its most important assets. Attaining a more complete understanding of the scope and organization of data resources can provide business intelligence and assist the decision-makers who are guiding the enterprise. One of the techniques used to obtain deeper knowledge related to the information contained in corporate databases is data modeling.
A data model is created by using a multi-step process. Generally, the creation of a data model uses the following framework.
A data model may need to be updated and modified as the elements and business requirements change. Relying on an outdated model can result in unreliable business intelligence and poor decisions based on the information it provides.
Data Modeling Versus Data Analysis
Data modeling is sometimes confused with the related technique of data analysis. Though both processes focus on maximizing the value of enterprise data resources, there are some important differences between modeling and analysis. This can be seen by looking at the main responsibilities involved with each discipline.
The primary tasks assigned to data modelers include:
Data analysts are primarily involved in these tasks:
Currently, both data modelers and data analysts are in demand in the business world. You can expect a slightly higher salary if you focus on the modeling aspects of enterprise data.
Developing Data Models That Get Used
One of the most important reasons that data models are developed is to assist non-technical decision-makers in understanding the complexities of the systems powering their business. Toward that end, it is necessary to make the model accessible to the associated stakeholders. Sometimes it is more beneficial to provide a simpler model that directly addresses the needs of the enterprise. The following are some points to keep in mind when developing a data model.
