Data Modelling and Database Design

Data modelling is about getting consistent data by having very clear definitions and structures, which means that it can be accessed and shared by different applications and different parts of the organisation rather than being trapped in a silo. It is about getting data into the state that ends the business being constrained by its own IT and forced to use workarounds due to software inflexibilities. It is about getting data into the state that when change occurs it does not spawn big IT migration projects. Data modelling is about enabling business to change because the data foundation has standards, consistency and is predictable.

Data is a valuable business resource, yet it is often locked away in databases obscured from decision makers. Data models need to be viewed as living things that will change, will grow, and will move away from their original purpose rather than something to become permanent and rigid. Getting this right early in a project not only brings the aforementioned flexibility to an organisation, but it reduces the lifetime of maintenance cost that poor data structuring induces. The right model means that data can be shared with other software, departments and with outside partners.

The Arc Software data team is very experienced in modelling data and can discuss the deepest theoretical concepts down to most granular level of detail with any technician, but we are a company that does, a company that builds, and we like to move from theorising to actually deploying solutions. Arc is by nature a very pragmatic group, perhaps with a dose of cynicism thrown in and we believe that it is important that the business receives the benefits of expert data modelling promptly. Data modelling can become very academic and theoretical to the point that it becomes very interesting to IT departments and no longer about finishing deliverables that can be used by the business.

Data belongs to the business and not to the software programmers or IT department. Data is a resource, a living process and it will change. If the modelling is done well then change is nothing to be feared.
