The primary purpose of your data warehouse is to serve as a centralized repository for historical data that can be quickly queried for BI reporting and analysis. Data modeling — which defines the database schema — is the heart of your data warehouse Learn more about designing Dimensional Data Models here. After designing your data model, the next step is to generate a physical schema, which synchronizes your model with the target database. This process is called forward engineering. Now generating a new schema for the database is a complex task. You need to execute all the physical changes, e.g., adding, removing, or altering entities, indexes, names, and relationship types, in the destination data warehouse. On top of that, you need to align the model with native requirements of different databases. And all this demands long, complicated scripts of coding. But where there is a complicated way, there’s also the Astera’s way.
Develop And Deploy High-Volume Data Warehouses TRY IT NOW! Automated Forward Engineering—The Astera Way Astera DW Builder is an end-to-end data warehouse automation tools that comes with an intuitive, no-code platform to cut down manual data warehousing tasks by almost 80%. This includes forward engineering as well. After you have designed your data model in Astera’s versatile data modeler, all Antigua and Barbuda Email List you need to do is generate its physical schema in the desired database prior to deployment. With Astera, you get different options to forward engineer the model. Let’s see how this is done. This is our sample dimensional data model—designed with Astera DW Builder—based on the fictitious World Wide Importers database. Sample Dimensional Model in Astera DW Builder Fig 1. Sample Dimensional Model in Astera DW Builder Step 1: Pick a Database of Your Choice First, you’d select the database where you want to generate your data model schema. You treat this as your data warehouse destination where you will deploy and populate designed models. Astera provides in-built, native support for some of the most popular data warehouse destinations and cloud providers. Simply click on the ‘Change Database Connection Info’ icon in the toolbar and select the desired provider and database.
Selecting the desired database connection Here, we have selected SQL server and added database details, including server and database names. Now you can automatically generate the physical schema and forward engineer your model onto the desired database. Step 2: Verify Your Model for Forward Engineering It’s important to verify your data model prior to forward engineering. Astera has an in-built data model verification system that automatically scans the model for any errors that can affect forward engineering or deployment. Select ‘Verify for Forward Engineering’ option from the toolbar and see if any common errors need to be fixed in the model. Data Model Verification Fig 3. Data Model Verification For example, two of our entities—Stock Items and Invoices—don’t have primary keys marked in their layout builders. The verification tool identifies these errors so they can be fixed prior to forward engineering and deployment. Verification Errors for Forward Engineering Fig 4. Verification Errors for Forward Engineering Mark the right column as primary key in the layout builder of both entities to get an error-free data model. Step 3: Select Preferred Method for Forward Engineering Astera gives you four different ways of generating a database schema. You can pick one from the forward engineering dropdown menu.
