| <h1>Cassandra Data Modeling Tools<a class="headerlink" href="#cassandra-data-modeling-tools" title="Permalink to this headline">¶</a></h1> |
| <p>There are several tools available to help you design and |
| manage your Cassandra schema and build queries.</p> |
| <ul class="simple"> |
| <li><p><a class="reference external" 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 class="reference external" 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 class="reference external" 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> |
| <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> |
