As customers modernize their data estate to Databricks, they are consolidating various data marts and EDWs into a single scalable lakehouse architecture which supports ETL, BI and AI. Usually one of the first steps of this journey starts with taking stock of the existing data models of the legacy systems and rationalizing and converting them into Bronze, Silver and Gold zones of the Databricks Lakehouse architecture. A robust data modeling tool that can visualize, design, deploy and standardize the lakehouse data assets greatly simplifies the lakehouse design and migration journey as well as accelerates the data governance aspects.
We are pleased to announce our partnership and integration of erwin Data Modeler by Quest with the Databricks Lakehouse Platform to serve these needs. Data modelers can now model and visualize lakehouse data structures with erwin Data Modeler to build Logical and Physical data models to fast-track migration to Databricks. Data Modelers and architects can quickly re-engineer or reconstruct databases and their underlying tables and views on Databricks. You can now easily access erwin Data Modeler from Databricks Partner Connect!
A Data Model reverse engineering is creating a data model from an existing database or script. The modeling tool creates a graphical representation of the selected database objects and the relationships between the objects. This graphical representation can be a logical or a physical model.
Overall, reverse engineering is valuable and a foundational step for data modeling. Reverse engineering enables a deeper understanding of an existing system and its components, controlled access to the enterprise design process, full transparency through modeling lifecycle, improvements in efficiency, time and cost savings, and better documentation which leads to better governance objectives.
The above scenarios assume you are working with a single data source, but most enterprises have different data marts and EDWs to support their reporting needs. Imagine your enterprise fits this description and is now embarking on creating a Databricks Lakehouse to consolidate its data platforms in the cloud in one unified platform for BI and AI. In that situation, it will be easy to utilize erwin Data Modeler to convert your existing data models from a legacy EDW to a Databricks data model. In the example below, a data model built for an EDW like SQL Server, Oracle or Teradata can now be implemented in Databricks by altering the target database to Databricks.
As you can see in the marked circle area, this model is built for SQL Server. Now we will convert this model and migrate its deployment to Databricks by changing the target server. This kind of easy conversion of your data models helps organizations quickly and safely migrate data models from legacy or on-prem databases to the cloud and govern those data sets throughout their lifecycle.
Above picture, we tried to convert a legacy SQL server-based data model to Databricks with a few simple steps. This kind of easy migration path allows and helps organizations to quickly and safely migrate their data and assets to Databricks, encourages remote collaboration, and enhances security.
Now let's move on to our final part; once ER Model is ready and approved by the data architecture team, you can quickly generate a .sql file from erwin DM or connect to Databricks and forward engineer this model to Databricks directly.
erwin Data Modeler Mart also supports GitHub. This support enables your DevOps team's requirement to control your scripts to your choice of enterprise source control repositories. Now with Git support, you can easily collaborate with developers and follow version control workflows.
In this blog, we demonstrated how easy it is to create, reverse engineer or forward engineer data models using erwin Data Modeler and create visual data models for migrating your table definitions to Databricks and reverse engineer data models for Data Governance and Semantic layer creation.
