It outlines the structure, format, semantics, quality, and terms of use for exchanging data between a <\/span><a href=\"https:\/\/www.huwise.com\/en\/glossary\/data-producer\/\"><span style=\"font-weight: 400;\">data producer <\/span><\/a><span style=\"font-weight: 400;\">and data consumers, providing a Service Level Agreement (SLA) and ensuring and enforcing data consistency, reliability, and compliance.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While a data contract can cover data exchange between any parts of a distributed data ecosystem, it is particularly vital for the delivery of <\/span><a href=\"https:\/\/www.huwise.com\/en\/glossary\/data-product\/\"><span style=\"font-weight: 400;\">data products<\/span><\/a><span style=\"font-weight: 400;\">, ensuring that data producers and consumers are clearly aligned in their expectations, building trust and increasing data consumption by both humans and AI.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Effectively it acts in the same way as any other contract between a buyer and a seller. Data contracts provide end users with a precise agreement regarding what the data product owner intends to deliver and how the data product should then be used, building trust between all parties.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Data contracts are both machine and human-readable and are implemented by a data product\u2019s output port or other means, and are published along with the data product on a data product marketplace. They can also be stored within data catalogs.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\"><br \/>\nWhat does a data contract contain?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">A data contract normally covers these key areas:<\/span><\/p>\n<ul class=\"list-tick-item\">\n<li><b>Data schema<\/b><span style=\"font-weight: 400;\">: how the data is structured, organized and formatted<\/span><\/li>\n<li><b>Data semantics<\/b><span style=\"font-weight: 400;\">: what the data means and how it should be interpreted\u00a0<\/span><\/li>\n<li><a href=\"https:\/\/www.huwise.com\/en\/glossary\/data-quality\/\"><b>Data quality<\/b><\/a><span style=\"font-weight: 400;\">: how accurate, complete and consistent the supplied data will be<\/span><\/li>\n<li><b>Terms of Use:<\/b><span style=\"font-weight: 400;\"> how the data can be used, accessed or shared, and who has access to it, supporting <\/span><a href=\"https:\/\/www.huwise.com\/en\/glossary\/data-governance\/\"><span style=\"font-weight: 400;\">data governance<\/span><\/a><span style=\"font-weight: 400;\">, security and compliance with regulations such as the <\/span><a href=\"https:\/\/www.huwise.com\/en\/glossary\/gdpr-general-data-protection-regulation\/\"><span style=\"font-weight: 400;\">GDPR<\/span><\/a><\/li>\n<li><b>Service Level Agreements (SLAs)<\/b><span style=\"font-weight: 400;\">: clear guarantees related to how frequently data will be delivered, data freshness and interface quality\u00a0<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">While they cover technical specifications it is vital that data contracts are easily understandable to business users in order to build trust in the data products they are accessing and consuming.\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400;\"><br \/>\nWhen is a data contract used?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Data contracts are used in multiple scenarios:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In real-time systems where data is exchanged automatically and feeds into and impacts other solutions. Examples include financial services\/trading solutions, healthcare and supply chain applications.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In data pipelines to define the structure, format and quality of automated data flows.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In event processing applications where information is shared within specific parameters, providing a clear guarantee of what will be delivered.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In the consumption of data products, defining quality requirements, format, and how data can be used, either within the organization or with business partners.\u00a0<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400;\"><br \/>\nWhy are the benefits of a data contract?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Data contracts essentially enable the sharing of distributed data at scale, increasing consumption, streamlining integration, improving compliance, and enabling smooth collaboration across teams. Thanks to this they provide seven key benefits:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Greater trust and usage as users understand exactly what data covers, quality levels and how it can be used.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Improved data quality by putting in place strict expectations in areas such as data accuracy, validation methods, frequency of updates and data freshness.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Lower integration costs and increased efficiency as there is a common understanding of data and integration and sharing is automated.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reduced data silos, with data sharing leading to effective communication and collaboration between data producers and data consumers.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Stronger data governance, enforcing policies around how data can be shared and consumed, and by whom, ensuring compliance with organizational and regulatory compliance requirements.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Fewer errors or disputes as expectations and responsibilities are clearly set out and agreed upon by both data producers and data consumers.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">They contribute to the creation of a data-driven culture, where data is democratized, shared and consumed across the business, leading to organizational benefits around more informed decision-making, greater efficiency, and lower risk.<\/span><\/li>\n<\/ul>\n","protected":false},"featured_media":0,"parent":0,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false},"tags":[],"letter":[351],"class_list":["post-34061","glossary","type-glossary","status-publish","hentry","letter-d"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 -
