To create a custom design or customize an existing one:

Plan the new design or modifications to an existing one. See Planning your design.
Create or modify projections. See Design fundamentals and CREATE PROJECTION for more detail.
Deploy projections to a test environment. See Writing and deploying custom projections.
Test and modify projections as needed.
After you finalize the design, deploy projections to the production environment.

The syntax for creating a design is easy for anyone who is familiar with SQL. As with any successful project, however, a successful design requires some initial planning. Before you create your first design:

Become familiar with standard design requirements and plan your design to include them. See Design requirements.
Determine how many projections you need to include in the design. See Determining the number of projections to use.
Determine the type of compression and encoding to use for columns. See Architecture.
Determine whether or not you want the database to be K-safe. It is recommended that all production databases have a minimum K-safety of one (K=1). Valid K-safety values are 0, 1, and 2. See Designing for K-safety.

Although you can write custom projections from scratch, it is recommended that you use Database Designer to create a design to use as a starting point. This ensures that you have projections that meet basic requirements.
