When more data becomes accessible on a second-by-second basis, industry-leading organisations are increasingly relying on data analytics to gain a competitive advantage and strategic insights. For instance, a business can serve a geo-targeted ad to a potential customer at the point of purchase if it incorporates in-store shopper data, purchase history and cell phone data.

The buyer is then more likely to purchase the top-of-mind brand over a rival who might be on the same shelf, but that time-sensitive nudge has not been delivered. Data catalog tools can assist data teams to extract these insights, which can then guide buying decisions for digital ads; therefore, in essence, the data catalogue allows for more effective and efficient ad purchases that retrieve greater returns.


1. Customized Treatment

Patient data from a range of systems, including diagnostic instruments, doctor reports, billing systems and, increasingly, wearable devices, are overwhelmed with healthcare systems, all of which are obtained and handled differently.

A data catalog empowers data scientists to provide the hospital with innovative services and explains how it encourages new procedures to comply with data protection and security regulations.

In order to develop customized medicine data catalog use scenarios, Velez is collaborating with different medical providers. One initiative includes improving the identification of the risk of breast cancer in a woman. In this initiative, for current patient records, as well as new data sets, a data catalog provides a single point of reference across the hospital. The resulting data collection for risk prediction is also cataloged, categorized and given data lineage.

2. Reforms of the Database System

Many companies store data in raw form in a data lake from various sources around the business with only the minimal level of metadata needed for data governance. Papudesu said this can delay enterprise-wide data adoption because it may be difficult for users to discover, comprehend and access data from the data lake.

Business analysts and data scientists are able to quickly access data when they need it by adding a managed data catalog on top of the data. They can also see where it originated and how it transforms as it passes through various applications. This will increase the use of the data lake, decrease duplicate data sets and minimize risks of compliance.

3. Minimizing repetitive spending on data

For advertisement, marketing and credit risk management purposes, many large companies constantly buy large quantities of third-party data.

However, due to organizational silos and decentralized data procurement systems, different lines of business end up buying the same data.

For third-party data, a data catalog may include a central repository and a structured acquisition process that makes it easier to do a comparative analysis to find redundancies across all external data sets. It may also assist data administrators to encode and automatically execute these data policies and agreements for data sharing.

4. Reforms of the Cloud

In the wake of COVID-19, companies are accelerating their cloud migration. One difficulty is that many cloud providers are optimized for any cloud or service with their own metadata management software. Another problem is that companies need to be aware of how and where physically processed are certain kinds of sensitive data sets.

In order to increase data visibility through on-site, cloud and hybrid environments, many companies turn to data catalogs. This case for the use of the data catalog also makes it easier to classify high-value data sets that should be prioritized based on use and lineage for speed and reuse. In order to ensure it is intact and stable, a data catalog can also help trace the technological lineage of data and ensure that no data is lost during a transfer.

5. Analytics on self-service

Democratizing knowledge through the organization is among the significant cases of data catalog use. Data is distributed through divisions of many organizations and processed in different systems. As a consequence, organizations fail to effectively and efficiently manage, retain and use their data.

A central portal to locate and access data through these data silos can be created by the data catalog. This makes it simple for users to know what information is available, where it comes from, how it is used and if it’s worthy of confidence.

Without waiting in the IT queue, a data catalog will also allow users to find the trustworthy, predefined and preapproved data they need to do their jobs. This will improve performance and speed up time for insights as users spend less time looking for information and more time working on analytics and sharing results.

6. Discovering confidential details

The most fascinating case of data catalog use, LaRock said, is the discovery of confidential data that an organization did not know existed. In systems that people have forgotten, client data, payment information, and passwords stored in plain text are often discovered.

The last thing you want is to be slapped with a fine from the GDPR because you have no idea what information you stored.

7. Management of Cloud Usage

IT departments are struggling to evaluate and appreciate user patterns and trends of cloud services as companies migrate to the cloud.

For this information, there can be dozens to hundreds of data sources, making it extremely difficult to put together and classify someone for consumption.

A data catalog can make it easier to stitch this information together so it can be accessed and analyzed for business cost analysis. A data catalog can also set up a translation layer for the source data so users can make appropriate comparisons of costs across different cloud providers and services.

What is a Data Catalog Doing?

Organizations depend on an average of 28 different sources for data and measurements, according to Deloitte. Multiply those 28 sources by the thousands of data sets in each one, and it is easy to understand why a data catalogue is required by companies. Data catalogue tools allow data teams and other data users to find, interpret and use data more easily and effectively by integrating data from different sources through a searchable, unified platform.
