disadvantages of a data repository?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">While centralizing specific data in a data repository brings benefits, it also leads to a number of potential challenges:<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><b>Data consistency<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Data comes from multiple different systems and sources, meaning it might vary in its structure, format and level of quality. This can require lengthy quality and governance processes to ensure consistency.\u00a0<\/span><\/p>\n<p><b>Single point of failure<\/b><\/p>\n<p><span style=\"font-weight: 400;\">If all relevant data is stored in a single system, issues such as IT crashes could prevent the data repository being used effectively, with data unavailable and inaccessible.<\/span><\/p>\n<p><b>Performance<\/b><\/p>\n<p><span style=\"font-weight: 400;\">As data within the data repository grows, and the number of users increases, performance can deteriorate, slowing down query response times and causing users to become frustrated.<\/span><\/p>\n<p><b>Security and governance<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Strong governance and access management capabilities are required to protect data as it is shared more widely through a data repository. As data is centralized it is more vulnerable to both security breaches by hackers and unauthorized access by employees. On the governance side it can be difficult to map ownership of data and enforce corporate governance policies and processes, risking non-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><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><b>Focus on technical users<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The biggest issue with data repositories is that they are designed solely to be used by technical experts. They are specialist tools and are not intuitive or seamless enough for business users. This limits data sharing and consumption, and is one of the major differences between a data repository and a <\/span><a href=\"https:\/\/www.huwise.com\/en\/glossary\/data-marketplace\/\"><span style=\"font-weight: 400;\">data marketplace<\/span><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><b>Do not provide access to all data<\/b><b><br \/>\n<\/b><span style=\"font-weight: 400;\">As well as not democratizing data access, data repositories only contain a subset of a company\u2019s data. While this may meet the needs of some technical users, it does not enable business users to easily discover and consume the data they require in their daily working lives.<\/span><\/p>\n","protected":false},"featured_media":0,"parent":0,"template":"","meta":{"_acf_changed":false,"inline_featured_image":false},"tags":[],"letter":[351],"class_list":["post-34091","glossary","type-glossary","status-publish","hentry","letter-d"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 -
