Data contracts
Enhance your organizations data foundation with reliable data exchange
The importance of data contracts
Data contracts provide a structured approach to managing data and ensuring that it meets predefined standards that are fit for its intended purpose. The importance of data contracts can be understood through several key aspects:
Standardization of data definitions
Data contracts standardize the definitions of data products, ensuring consistency across platforms and simplifying data sharing. This approach accelerates onboarding for both tenants and data products by providing a clear framework for data expectations, enabling smooth integration across data domains and with systems such as data quality tools and data governance platforms.
Linking business and technical metadata
Data contracts link business and technical metadata, ensuring that data definitions, purposes, and quality standards are consistently understood across both domains. This linkage aligns data assets with business objectives, making it easier for teams to navigate, govern, and use data effectively.
Data consistency and accuracy
Ensure reliable data by preventing errors and inconsistencies when your data moves between teams or systems and prevent the breakage of downstream systems by specifying rules around scheme changes and updates.
Improved collaboration and communication
By setting clear expectations between data producers and consumers, this creates alignment across your engineering, data science and business teams, fostering smoother collaboration and reducing misunderstanding and miscommunication.
Data quality and governance
Enforce data quality assurance and governance by establishing rules that ensure your data meets quality standards and complies with regulation and policies.
Operational efficiency
Automate validation checks to reduce the need for manual quality assurance processes and minimize the risk of errors or delays due to misaligned data through smooth system integration to reduce downtime.
Mitigating risks
Minimize the risk of data-related failures, such as schema mismatches, incomplete data, or unexpected changes, and prevent unintentional disruptions to dependent systems by implementing robust version control and clear communication. Data contracts also allow for explicit categorization of PII and data classification, strengthening data security and ensuring compliance with privacy regulations.
Scalability and futureproofing
Scale data pipelines efficiently without having to rewrite rules or redefine expectations constantly and drive innovation with a reliable data foundation.
Data contract principles
Implementing a robust and enforceable data contract requires adherence to a set of core principles. These principles act as best practices and guide development in a way that ensures the delivery of greater business insights and efficiency to allow business to achieve their objectives.
Schema definition and enforcement
Data contracts must define a clear and unambiguous schema to ensure that both data producers and consumers understand the data structure and enforce strict validation before the schema is entered into the system.
Versioning and compatibility
Updates and changes to the data contract should be versioned and communicated clearly to all parties to prevent disruption and the data contract should make sure that any changes to data structures do not break existing consumers and ensure backward and forward compatibility.
Data quality assurance
Data contracts must define acceptable thresholds for data accuracy, consistency, completeness, and how frequently the data should be updated or refreshed.
Ownership and accountability
Define the roles and responsibilities of data ownership at each stage to ensure the accountability and timely resolution of issues. When data does not meet the expected quality or structure, the data contract should outline the escalation process.
Automation and monitoring
To reduce the need for manual interventions and allow for the quick identification of discrepancies or breaches, data contracts should be enforced automatically through systems that validate the data before it enters the pipeline and include mechanisms for monitoring data quality and adherence to the contract in real time.
Flexibility with guardrails
While maintaining strict validation, data contracts should be flexible enough to accommodate evolving business needs without breaking existing workflows. In cases where the contract cannot be fully met, fallback mechanisms should ensure minimal disruption.
Governance and security
Comply with relevant regulations such as GDPR, HIPAA, or CCPA, and specify who can access, modify, or interact with the data, ensuring it is handled in accordance with governance and privacy policies.
Transparency and communication
By clearly documenting the terms of the data contract and making it easily accessible for all relevant stakeholders, this facilitates open and continuous communication channels between the data producers and consumers around expectations, changes, and potential issues.
Error handling and fail-safe mechanisms
Data contracts should include procedures for handling data errors, ensuring that systems fail gracefully rather than catastrophically. In cases where data does not meet contract expectations, retry mechanisms or error correction procedure should be in place to minimize any possible disruption.
Scalability and evolution
As organizations grow and their needs change, data contracts should be designed to be scalable and flexible, allowing new data sources and consumers to be added without requiring major rework or disrupting core data operations.
Single source of truth
Data contracts should serve as the single source of truth for data definitions, structures, and quality expectations, providing a unified reference for both data producers and consumers. By centralizing contract terms and standards, data contracts eliminate ambiguity and ensure that all teams work with consistent, accurate information throughout the data lifecycle.

Outlined below are the essential steps for implementing data contracts that align with the principles previously described, ensuring comprehensive management, optimization, and utilization of your data assets:
Phase 01
Identify stakeholders
Identify the data producers and consumers and involve data governance and legal/compliance teams to oversee data quality and privacy and ensure compliance with relevant regulations.
Phase 02
Define data contract objectives
Define the purpose of the data being shared, which datasets or fields will be covered, the scope of data sharing, and clarify the expected outcomes by implementing the data contract.
Phase 03
Design the data schema
Define the exact data fields and types, and whether they are mandatory or optional. Then specify any validation conditions or acceptable ranges and provide sample data to clarify stakeholder expectations. Open-source data contract schemas, like those in datacontract.com, can serve as a starting point to build robust schema definitions.
Phase 04
Establish data quality standards
Create a set of standards that clearly define expectations on accuracy, completeness, consistency and timeliness. Service Level Agreements (SLAs) can be used for data availability, delivery, schedules, and response times.
Phase 05
Define ownership and accountability
Establish the data owners and consumers and define a clear escalation path for resolving any issues, discrepancies, missing data or non-compliance that may arise.
Phase 06
Set versioning and change management policies
Implement a version control system for tracking data schema or contract changes and ensure that updates to the data schema will not break existing systems through backward compatibility. A change notification policy should also be set to notify relevant stakeholders.
Phase 07
Implement automation for data validation
Implement automated checks, monitoring tools and fail-safe mechanisms to validate the data before it is passed downstream and check for any breaches in data quality, availability, or contract compliance.
Phase 08
Document the data contract
Create a detailed document outlining the schema and data definitions, quality metrics, SLAs, change control process and access permissions.
Phase 09
Communicate the data contract
Ensure all stakeholders understand the data contract, its requirements and their responsibilities though onboarding and training and continuous feedback loops so users can report any issues, request enhancements, or seek further clarification.
Phase 10
Ensure compliance with regulatory standards
Verify that the data contract aligns with any relevant legal and regulatory requirements to ensure data privacy and security.
Phase 11
Continuous monitoring and improvement
Establish metrics and KPIs to measure the effectiveness of your data contracts and make ongoing improvements. This ensures that your data solutions continue to deliver value and evolve with changing business needs.
