1. Data discovery and ingestion
Integrating various data sources into the catalog can be time-consuming and complex. You must ensure that the catalog can discover and ingest data from all relevant sources for your organization, including databases, data lakes, and third-party applications.
In addition to ingestion, data discovery is a significant challenge in data catalog projects. Making assets searchable isn’t enough, but leveraging metadata to map their relationships is essential.
Prukalpa Sankar, co-founder at Atlan, echoes this sentiment when she says that a fundamental data cataloging challenge isn’t the search algorithm:
“*The real challenge lies in building relevancy into data discovery — i.e. being able to curate and tag datasets and metadata so that we could build meaningful relationships between data assets and our search algorithms could understand what data was actually relevant to a user.*”
2. Data quality and accuracy
Ensuring that the information in the catalog is accurate and up-to-date is critical. This may require automating certain aspects of data validation processes and auto-updating metadata, schemas, and other data catalog components.
3. Scalability and performance
Despite the growing volume and complexity of your data, your data catalog should be able to scale operations. This requires automating several aspects of data and metadata management, such as identifying unused assets, accelerating metadata documentation, and propagating classifications across sensitive data assets.
4. Data security and privacy
Safeguarding sensitive data is essential to ensure data integrity and privacy, while complying with data protection laws and regulations. Your catalog should have robust security measures in place, such as data encryption, hashing and masking policies, access control, policy propagation via lineage, and auditing capabilities.
5. User adoption and training
Your team must be comfortable using the data catalog, which may require training and ongoing support. Encourage adoption by choosing a catalog that integrates into your existing workflows and enables cross-team collaboration.
6. Data governance and compliance
According to Lisa Ehrlinger, a Data Management and Data Quality Senior Researcher at Software Competence Center Hagenberg (SCCH):
“It is of utmost importance to build a comprehensive data governance strategy around the deployment of a data catalog to support organizations in finding and understanding all their data.”
Your catalog should support data governance policies and help maintain regulatory compliance. This may involve implementing processes for data lineage, data classification, and data retention.
7. Integration with other tools
Your data catalog should integrate well with your existing data ecosystem, including data analytics platforms, visualization tools, data storage solutions, and homegrown data products.
8. Vendor lock-in
Be cautious of vendor lock-in when procuring a data catalog solution. Ensure that the chosen solution allows for flexibility, doesn’t come with archaic licensing fees, and can evolve with your organization’s needs.
The best way is to look for partners rather than vendors, offering solutions that are open by default and with a pay-as-you-go pricing.
9. Maintenance and support
A data catalog requires ongoing maintenance to ensure that it remains useful and relevant. This may involve updating metadata, fixing bugs, and enhancing functionality. Choose a solution provider that offers round-the-clock support to help address any issues that arise.
10. Cost management
The costs of procuring, deploying, and maintaining a data catalog can be significant. Be sure to budget for these expenses and monitor them closely to ensure that you are receiving a good return on your investment.
By being aware of these challenges and proactively addressing them, you can help ensure the success of your data catalog implementation and maximize its benefits for your organization.
So, what’s the best way to deal with these data catalog challenges? We’ve put together an action plan to help you out.
