Data Quality

Built to ensure data quality

Data Model Pack started from the wish to share the knowledge and the lessons learned from many database design projects. We focus on keeping the data models close to business use cases and flexible enough to anticipate new business requirements. We follow the best practices in database design to ensure data quality and to enable easy customization for future applications.

Data Model example

D/01

Database design best practices

We are implementing the best practices in database design through well-thought constraints definitions: PK, FK, NOT NULL, etc. All these directly contribute to ensure the overall data quality for the new application that will use the database schema.

D/02

Flexible rules for database logic

We have built the data models starting from the idea to make the database schema flexible and customizable. As an example, whenever possible, we have created dimension tables that store what we call list of values: Sales_Channels, Delivery_Type, Discount_Type, Payment_Method etc.
