Data Lakes and Data Lake Rescue

Optimizing data collection and centralization
with structured data lakes

Are Your Analytics Drowning in Data Lakes?

The foundational, crucial requirement for supporting analytical solutions is a rich, reliable source of data. Understandably, many data-related initiatives begin with the comprehensive collection and centralization of data. There are many collection strategies that are currently in use, including Data Lakes.

Swimming in treacherous waters

Data Lakes are general repositories in which data is stored in its natural format. Data objects within the “lake” may be text files, database tables, blobs, etc. Data may be structured (e.g. tabular, XML, etc.) or unstructured (e.g. images, PDF’s, emails, texts, etc.). 

The goal of the Data Lake is to offer a single storage location for all enterprise data to support analytics and data visualization. Often Data Lakes utilize non-database, “big data” solutions (e.g. Hadoop) to accommodate and ingest unstructured data at incredible speeds.

On its face, the construction of a Data Lake seems like an intuitive and practical first step.  However, many Data Lakes become dumping grounds and data graveyards, in which undocumented data is recklessly deposited with the hope of supporting some undefined, future use. The typical Data Lakes suffers from a variety of defects:

  • Limited concern for the validity, completeness, and understanding of the data being collected
  • Insignificant regard for the compliant and responsible treatment of personally identifiable information (e.g. customer contact details, addresses, tax identification numbers, etc.; “PII”)
  • Insufficient data mastering and history accumulation
  • Lackluster performance of Big Data query tools often require data lake content to be (redundantly) re-instantiated in a structured environment (i.e. database) to be truly usable

Our team can clean up your existing data lake or create a more effective one through the establishment of a Structured Data Lake.

Comprehensive data quality


Structured Data Lakes vs. Typical Data Lakes


  • Data is ingested in its natural form with little or no transformation
  • All data necessary to prepare a structured analysis is co-located within the Lake (rather than just selected structures or attributes)
  • Rapid implementation
  • Flexible accommodation of new and/or changed data structures


  • Pronounced emphasis on metadata
    (structure-level, attribute-level, domain-level, applicability conditions, etc.)
  • Responsible tracking and accumulation of historical performance
  • Responsible data mastering techniques
  • Structured data storage for optimized consumption by a broader collection of query tools
