Snapshots,can become a nightmare to deal with because quite often data professionals need to query the data from a point in time. During this chapter, we will talk about the ways that dbt can help track row changes and maintain change history using snapshots. If you are familiar with dimensional data modeling

Jinja, Macros, and Packages,s. However, have you ever found yourself writing repetitive SQL code that you wish you could easily use throughout your transformations without needing to rewrite the same code every time? This is where Jinja in conjunction with dbt comes in and adds extensible programmatic capability to your SQL co

dbt in Production,ed many aspects of dbt ranging from utilizing seed files, building incremental models, and using Jinja and macros to fill in the gaps where SQL gets repetitive. So far, we have only run these transformations in a development environment, but once you are ready for data consumers to utilize the data

Book 2023testing. It explains how dbt is revolutionizing data transformation and the advantages that a command-line tool like dbt provides over and above the use of database stored procedures and other ETL and ELT tools that handle data transformations. You’ll see how to create custom-written transformations

Models,. One of the main reasons for this is that software engineering best practices, which are also applicable to data teams, are not used. For example, data transformations tend to not be modular, data quality testing is infrequently implemented, and version control is not used.

Snapshots,ical to a Type-2 SCD where a record is stored for both the current and changed rows in the same table and differentiated based on status and timestamp columns. In other data model designs, the concept exists, but may be referenced as a different name.
