Luna Modeler Solutions

Data modeling challenges Luna Modeler solves

Most data modeling problems are not about drawing boxes — they are about the database getting ahead of the design. Below are the jobs teams hire Luna Modeler for: documenting a database nobody understands, catching schema drift before a release, mapping where data comes from, and recording who owns it. Each one is solved inside a single ER diagram you keep on your own machine.

Data modeling vs ER diagram

Drawing an ERD is only the start. See how offline data modeling in a dedicated tool goes further than the quick ERD features built into IDE and database tools.

Database schema drift

Schema drift happens when your database stops matching its design. See what schema drift is, how it differs from schema evolution, and how Luna Modeler helps you spot it.

Database documentation

Inherited a database with no docs? Follow a clear plan to reverse engineer it, draw an ER diagram, add notes and produce database documentation with Luna Modeler.

Data lineage diagram

See where your data comes from and where it flows. Map source-to-target data lineage visually inside an ER diagram with Luna Modeler — no heavy platform. Free trial.

Data governance diagram

Show data owners, sensitive (PII) fields and retention rules right inside your ER diagram. A simple, visual way to document data governance in Luna Modeler.

Data model with flowchart and data flow elements

Add flowchart and data flow diagram elements straight to your database model. See how Luna Modeler makes a data model more informative, clear and useful.

Impact analysis

Impact analysis shows what depends on a table before you change it. See how Luna Modeler infers dependencies and adds referenced objects to map the blast radius.

Custom fields and templates

Add custom fields to your data model, show them on the diagram and in reports, then turn them into code with custom templates. See how Luna Modeler does it.

Data Model Types

Luna Modeler supports all three main data model types: Physical data model, Logical data model as well as Conceptual data model. In addition to database-specific visualizations, you can also enhance diagrams with Data Flow, Flowchart or Use Case diagramming elements or other predefined graphics.
