What is a Maextro Data Model?

A Maextro Data Model explains the process, the views and the fields that each user can interact with as well as which rules are applied to data at the appropriate data steps.

In our methodology, the first objective of the model is to capture the process owners, data gatherers and approvers involved in the process. The second objective is to capture the fields required within each form that the user will populate (these are called views). The third objective is to capture relevant data rules for the fields (examples: make field x mandatory, conditional values and default values etc.).

As part of our methodology our services team are trained in data processes and their typical data models. We are here to help the client but also challenge existing data processes using a hybrid/agile style.

Data Modelling is one of those areas which can often go unexplored. As a result, a number of common question arise when we talk to our customers about modelling their data. Here are a selection which we've answered below.

A data model is an abstract representation that defines the structure, relationships, and constraints of data within a system or database. It serves as a blueprint, outlining data entities, attributes, and their interconnections, ensuring efficient data storage, retrieval, and manipulation for various applications.

Data modelling is the process of creating abstract representations, known as data models, to describe the structure, relationships, and constraints of data within a system or database. It involves identifying data entities, attributes, and their interconnections, providing a blueprint for efficient data storage, retrieval, and manipulation. Data modelling ensures data accuracy, consistency, and integrity, facilitating effective communication between stakeholders, developers, and database administrators during the software development life cycle. By defining the data's organisation and logic, data modelling helps in building robust and scalable systems that support business requirements and aid decision-making processes.
