Data curation is important in today’s world of data sharing and self-service analytics, but I think it is a frequently misused term. When speaking and consulting, I often hear people refer to data in their data lakes and datawarehouses as curated data, believing that it is curated because it is stored as shareable data.
JSON (JavaScript Object Notation) is a popular data format for exchanging information between servers and web applications. Its lightweight and readable structure makes it a preferred choice for many developers and dataanalysts. Instead, JSON files must be stored in your datawarehouse (e.g., Snowflake).
Cloud datawarehouses provide various advantages, including the ability to be more scalable and elastic than conventional warehouses. Can’t get to the data. All of this data might be overwhelming for engineers who struggle to pull in data sets quickly enough. However, there are ways to get around this.
But, on the back end, data lakes give businesses a common repository to collect and store data, streamlined usage from a single source, and access to the raw data necessary for today’s advanced analytics and artificial intelligence (AI) needs.
They are responsible for designing, building, and maintaining the infrastructure and tools needed to manage and process large volumes of data effectively. This involves working closely with dataanalysts and data scientists to ensure that data is stored, processed, and analyzed efficiently to derive insights that inform decision-making.
Instead of spending most of their time leveraging their unique skillsets and algorithmic knowledge, data scientists are stuck sorting through data sets, trying to determine what’s trustworthy and how best to use that data for their own goals. The Data Science Workflow. Closing Thoughts.
