| <h1 class="page">Cassandra Data Modeling Tools</h1> |
| <div class="paragraph"> |
| <p>There are several tools available to help you design and manage your |
| Cassandra schema and build queries.</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p><a href="https://hackolade.com/nosqldb.html#cassandra">Hackolade</a> is a data |
| modeling tool that supports schema design for Cassandra and many other |
| NoSQL databases. Hackolade supports the unique concepts of CQL such as |
| partition keys and clustering columns, as well as data types including |
| collections and UDTs. It also provides the ability to create Chebotko |
| diagrams.</p> |
| </li> |
| <li> |
| <p><a href="http://kdm.dataview.org/">Kashlev Data Modeler</a> is a Cassandra data |
| modeling tool that automates the data modeling methodology described in |
| this documentation, including identifying access patterns, conceptual, |
| logical, and physical data modeling, and schema generation. It also |
| includes model patterns that you can optionally leverage as a starting |
| point for your designs.</p> |
| </li> |
| <li> |
| <p>DataStax DevCenter is a tool for managing schema, executing queries |
| and viewing results. While the tool is no longer actively supported, it |
| is still popular with many developers and is available as a |
| <a href="https://academy.datastax.com/downloads">free download</a>. DevCenter |
| features syntax highlighting for CQL commands, types, and name literals. |
| DevCenter provides command completion as you type out CQL commands and |
| interprets the commands you type, highlighting any errors you make. The |
| tool provides panes for managing multiple CQL scripts and connections to |
| multiple clusters. The connections are used to run CQL commands against |
| live clusters and view the results. The tool also has a query trace |
| feature that is useful for gaining insight into the performance of your |
| queries.</p> |
| </li> |
| <li> |
| <p>IDE Plugins - There are CQL plugins available for several Integrated |
| Development Environments (IDEs), such as IntelliJ IDEA and Apache |
| NetBeans. These plugins typically provide features such as schema |
| management and query execution.</p> |
| </li> |
| </ul> |
| </div> |
| <div class="paragraph"> |
| <p>Some IDEs and tools that claim to support Cassandra do not actually |
| support CQL natively, but instead access Cassandra using a JDBC/ODBC |
| driver and interact with Cassandra as if it were a relational database |
| with SQL support. Wnen selecting tools for working with Cassandra you’ll |
| want to make sure they support CQL and reinforce Cassandra best |
| practices for data modeling as presented in this documentation.</p> |
