DbSchema includes a flexible reports designer for the Web. The designer can create dynamic HTML pages where you can combine charts, master-details tables and input fields. The sheets can be run on a stand-alone server. The DbSchema model holds its image of the schema, separate from the database.
Compare the schema model with any database, merge the differences in the model or commit them in the database, or generate SQL diff scripts. The engine allows to automate all kinds of processes, like schema reverse-engineer or schema deployment, generate HTML5 documentation, execute database queries, etc. If the database lacks foreign keys, you can create virtual foreign keys. They are used for the design and by the Data Explorer or Query Builder.
The virtual foreign keys are saved to the model file and not implemented in the database. DbSchema can visualize the MongoDB databases as diagrams, implement validation rules, write native MongoDB queries, and explore the data.
Creating new collections or fields using DbSchema will implement the schema validation rules in the database.
