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.
