In the chapter "Data Contracts," we explore the critical role of data contracts within the data mesh framework, a concept vital for maintaining data integrity and facilitating seamless interactions between the source and consumer domains. Data contracts serve as a set of rules or agreements designed to ensure that any changes in data schema or format by one domain do not adversely affect another, thus preserving autonomy while mitigating the risk of disruptions. This chapter delves into various forms of data contracts—verbal, written, and automated—highlighting their importance in ensuring data quality and consistency across domains. Through a detailed examination of an exemplary data contract articulated in a YAML-like declarative syntax, we uncover the mechanisms for validating data sets, from ensuring email address validity to checking for data freshness and consistency in variable relationships. The discussion extends to the enforcement of these contracts, ensuring data compliance and integrity from creation to consumption. This concise exploration not only sheds light on the foundational principles of data contracts but also their pivotal role in the modern data ecosystem, underscoring the balance between independence and interdependence within organizations.
Machine learning models are only as good as the data they are trained on, which is why understanding data architecture is critical for data scientists building machine learning models.
This course will teach you:
The fundamentals of data architecture
A refresher on data types, including structured, unstructured, and semi-structured data
DataWarehouse Fundamentals
Data Lake Fundamentals
The differences between data warehouses and data lakes
DataLakehouse Fundamentals
Data Mesh fundamentals for decentralized governance of data including topics like data catalog, data contracts and data fabric.
The challenges of incorporating streaming data in data science
Some machine learning-specific data infrastructure, such as feature stores and vector databases
The course will help you:
Make informed decisions about the architecture of your data infrastructure to improve the accuracy and effectiveness of your models
Adopt modern technologies and practices to improve workflows
Develop a better understanding and empathy for data engineers
Improve your reputation as an all-around data scientist
Think of data architecture as the framework that supports the construction of a machine learning model. Just as a building needs a strong framework to support its structure, a machine learning model needs a solid data architecture to support its accuracy and effectiveness. Without a strong framework, the building is at risk of collapsing, and without a strong data architecture, machine learning models are at risk of producing inaccurate or biased results. By understanding the principles of data architecture, data scientists can ensure that their data infrastructure is robust, reliable, and capable of supporting the training and deployment of accurate and effective machine learning models.
By the end of this course, you'll have the knowledge to help guide your team and organization in creating the right data architecture for deploying data science use cases.
