 ## Roadmap
 
-* define a DSL for modeling database
-  * describe entity-relationship diagrams (ERD) using MERISE notation
-  * describe physical diagrams (PD)
-* provide a command-line tool for all operations
-* render models into diagrams
-  * ERD to MERISE MCD diagrams
-  * ERD to Chen notation diagrams
-  * PD to MERISE MLD diagrams
-* validate model
-* convert across different database reprentations
-  * to convert ERD to PD
-  * to convert PD to database specific SQL
-  * to reverse-engineer database-specific SQL to PD
-  * to reverse-engineer PD to ERD
-* support multiple physical models
-  * sql
-  * nosql
-* support multiple SQL and NoSQL languages
-  * SQL: postgresql
-  * SQL: mariadb
-  * NoSQL: redis
-  * NoSQL: mongodb
-  * NoSQL: cassandra CQL
