About the DataStax Enterprise 5.1 Developer Guide 

Information for developers about creating enterprise-level applications with DataStax Enterprise 5.1.

The Developer Guide provides information for creating enterprise-level applications that require real-time always available storage, search, and analytics. DataStax Enterprise seamlessly integrates your code, allowing applications to utilize a breadth of techniques to produce a mobile app or online applications.

Tip: Developing applications requires a basic understanding of how DataStax Enterprise works and how it differs from a relational database. In conjunction with this guide, you should refer to the Architecture Guide for background information. This will save you a lot of time when developing your data models, applications, and using the features in DataStax Enterprise. To get started, be sure to read the DataStax Enterprise 5.1 FAQ and Architecture in brief.

As a developer, you must be familiar with data modeling and CQL.

To ensure that you get the best experience in using this document, take a moment to look at the Tips for using DataStax documentation. This page provides information on search, navigational aids, and providing feedback.

DataStax supplies a number of drivers so that CQL statements and search commands can be passed from client to cluster and back. Other tasks can be accomplished using OpsCenter.

This guide includes documentation for:

Install methods
Types of installs generally used by developers.
DSE Analytics
DSE Analytics uses Apache Spark™ to perform analytic queries over large sets of data. Topics include starting, configuring, running commands against a remote cluster, accessing data, and a number of examples.
DSE Graph
A graph database for storing information about the relationships between entries. Topics include getting started, terminology, data modeling, anti-patterns, importing data, tools, and graph analytics.
DSE Search
DSE Search simplifies using search applications for data that is stored in a database. DSE Search integrates Apache Solr™ to manage search indexes with a persistent store.
DSEFS
DataStax Enterprise File System is distributed file system for storing very large sets of data and encapsulated that data across a DSE cluster. It can be stored for processing by DSE analytics and other tools. It's a replacement for CFS (Cassandra File System) and is roughly equivalent to HDFS.
DataStax Studio
An IDE for syntax validation, type checking, validations specific to the domain, and content assistance for CQL (Cassandra Query Language).
DataStax DevCenter
An IDE for creating and running statements against DataStax Enterprise.
