在我们目前的快节奏社会中，数据正在快速生成。在2020年，人类每天都会产生2.5千万千分之一的数据，并在年底44 Zettabytes将构成整个数字宇宙。但所有这些数据在哪里？如何存储它以及它如何使用？
什么是数据湖？
许多组织将它们的数据存储在一个数据湖, which is a central repository that houses large volumes of raw data, including structured, semistructured and unstructured data. Typically, an organization’s data lake stores data from multiple different sources across the enterprise. But a data lake can easily become a data swamp if it is not properly governed. And without a data catalog, it is impossible to easily find, understand and trust the data in your data lake, resulting in decreased productivity and increased cost.
The challenges of an ungoverned data lake
Without a governance foundation and a data catalog in place, you risk not getting the full value out of your data lake investment. In fact, according to anIDC研究, in some cases, organizations experienced a productivity loss of 25% when they did not implement a governed data catalog on top of their data lake. An ungoverned data lake can result in:
- Difficulty finding and understanding data.Without the business context around data, it is hard to know what data is in the lake, what the data means, who owns it and whether it’s relevant for use.
- Lack of trust in the data.There is no visibility into where data in the lake is coming from or if it is accurate or trustworthy to use.
- Inability to access the data.数据所有者无法控制数据湖中的数据是如何使用的，因此它们必须限制跨企业的访问，以确保符合数据的使用。
Ultimately, an ungoverned data lake can cost an organization millions of dollars due to time wasted trying to find the right data for analysis, which is a massive loss for any organization.
受管制数据湖的好处
数据湖泊为您的数据提供了基本存储，并且对于许多大型企业而言是必要的。但是，数据湖泊只有在与数据目录中受到管理时才有效。使用综合治理实现数据目录以管理数据湖是成为数据驱动组织的关键步骤。它可以帮助您的组织：
