Data modelling services involve the creation of conceptual, logical, and physical data models that represent an organisation's data in a structured and organised manner. Basically, we look at how your data sources and entities relate to each other and whether there is a need for different approaches which could improve your data assets. We can also create these from scratch.
Some of the key activities involved in data architecture services are:
Conceptual data modelling
This involves creating a high-level data model that represents the overall structure of the data and the relationships between data entities.
Logical data modelling
This involves creating a more detailed data model that defines the tables/entities, their attributes, and the relationships between them.

Physical data modelling
This involves creating a data model that maps the logical data model to the physical data storage structures, such as databases, tables, and fields.
Database design
This involves designing the schema and table structures that will be used to store data in the organisation's databases.
Data dictionary creation
This involves documenting the data elements, their definitions, and their relationships in a data dictionary, which serves as a reference guide for all users of the data.
Data Modelling
Data modelling services are critical for ensuring that an organisation's data is accurate, consistent, and organised in a way that enables efficient data management and supports effective decision-making.
