A data catalog is a library of metadata that allows you to find the right information. It enables you to easily discover data, whether it’s from a public database or a private one. Typically, metadata is a structured document that is stored in a separate file.
It can be stored in a human-readable format or a binary form. The human-readable format is easier to read and understand.
Data catalogs are essential tools that allow you to find the right data and to understand its relationship with other data. They also provide you with a centralized view of your entire data stack.
You can use a data catalog for all kinds of data, from financial information to weather reports. For example, you could use a library catalog to discover all books in a country. Or, you could use it to find all records about a business.
A data catalog identifies relationships between data, terms, and physical assets. This lets you identify connections that you may not have previously known about. As a result, you can find the best data for your needs.
Data catalogs also help you find the right information, even if you don’t know where it’s located. For example, if you’re working with a customer’s database, you might not know where to start. But a data catalog can tell you where your data is located, how it’s related to other data, and what data is available to you.
A data catalog can be maintained on your premises or in the cloud. A data catalog may include your own business information, as well as data from your customers. In fact, it may be able to connect to your customers’ databases to help you find their information.
