+Vantage is a type-safe, easy to use database toolkit for Rust that focuses on developer productivity
 without compromising performance. It allows you to work with your database using Rust's strong type

+system while abstracting away the complexity of SQL queries.
+
+Vantage enables use of Model Driven Architecture (DSL/DDD) patterns in your Rust applications. This
+approach separates business and application logic from underlying platform technology. Vantage uses
+native Rust syntax to define Entities, Attributes, Validations, Relations, Actions and mapping them
+to one or several persistence layers - such as SQL, NoSQL or APIs.
+
+The long-term goal for Vantage is to be a building block for configurable ERP/CRM/HR/Supply business
+management system rivaling Odoo or Salesforce written entirely in Rust.
