Rakenne is a database modeling tool.
|
|
|
|
Its goal is:
|
|
|
|
* to provide a DSL for modeling database
|
|
* to describe entity-relationship diagrams (ERD) using MERISE notation
|
|
* to describe physical diagrams (PD)
|
|
* to provide a command-line tool for all operations
|
|
* to render models into diagrams
|
|
* ERD to MERISE MCD diagrams
|
|
* ERD to Chen notation diagrams
|
|
* PD to MERISE MLD diagrams
|
|
* to validate model
|
|
* to 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
|
|
* to support multiple physical models
|
|
* sql
|
|
* nosql
|
|
* to support multiple SQL and NoSQL languages
|
|
* SQL: postgresql
|
|
* SQL: mariadb
|
|
* NoSQL: redis
|
|
* NoSQL: mongodb
|
|
* NoSQL: cassandra CQL
