![]() ![]() This is where data modeling comes in, and if you are building a stack with a data warehouse at the center, it needs to be addressed. How do you actually transform data from many different sources into a set of clean, well tested data sets?ĮLT introduces a new problem, you end up with a data warehouse full of messy datasets from your newly set up data integration tools and no idea how to use them. ![]() We’ve written about this change if you’d like more information on why we think the shift towards SQL based warehousing is the right one and how it can help you move quickly, especially as a startup! Data modeling Additionally with the rise of engineering inspired data modeling tools (such as Dataform), it’s possible to manipulate data via SQL in a well tested, reproducible way. Warehouses and SQL have many benefits and the scalability limits are (mostly) gone. Before Snowflake and BigQuery, organizations with truly massive data would have avoided them due to limited scale, and instead opt for solutions such as Apache Spark, Dataflow, or Hadoop MapReduce like systems. Where you move all your data to so you can query it together.Ī lot about data warehousing has changed over the last 10 years, data warehouses now scale to unprecedented levels. Data integration to other SaaS products.Event collection > Data warehouse / SaaS tools / CRMsįor the rest of the article we’ll consider these as two different data integration problems:.Typically you need to move data between various places such as: How do you move data between databases and services? There is some overlap with collection here. Tracking everything that you want to use for analytics in events avoids needing to join in other data sources at analysis time and lends itself well to product analytics where ordering of events is important to consider. How do you collect event data from across all of your different applications, web, app, backend services and send them to other systems or your data warehouse.Ĭonceptually straightforward, so not much to say here! Event based analytics is usually the easiest place to start and most off the shelf solutions are built around this. This is an ELT architecture (extract, load, transform) as opposed to a more traditional ETL architecture, and can support companies of all sizes (perhaps with the exception of extremely large enterprises). ![]() There is a prevailing model of a data stack that we consistently see the world moving toward, that’s probably best summed up by this diagram. Similarly in one or two cases I’ve shared my reasons for not recommending them. Where I have significant experience with a product, I’ll let you know and provide more detail on why.
