CQL for client applications

by Amresh Singh | October 2013 | Open Source

In this article, by Amresh Singh, the author of Instant Cassandra Query Language discusses about how CQL can be used for client applications.

CQL 3 is being pushed as a standard for building applications over Cassandra. Running CQL queries on the shell is fine for viewing and modifying the data for testing purpose, but the actual use of CQL lies with building applications just the way SQL is used with JDBC.

Next, we are going to explain the three ways using which you can build Java applications over Cassandra (it's possible to build applications in other programming languages as well via appropriate drivers and clients).

Defining a Data Model for Spatial Data Storage

by Simon Greener Siva Ravada | October 2013 | Enterprise Articles Oracle

In this article by Simon Greener and Siva Ravada, the authors of Applying and Extending Oracle Spatial, we provide a SQL schema and functions that facilitate the storage, update, and query of collections of spatial features in an Oracle database.

Oracle Spatial and Graph provides a SQL schema and functions that facilitate the storage, update, and query of collections of spatial features in an Oracle database. Oracle Spatial and Graph is the new name for the feature formerly known as Oracle Spatial. In this article, we refer to this feature as Oracle Spatial for the sake of simplicity. We also focus exclusively on spatial feature of Oracle Spatial and Graph in this article. Oracle Spatial mainly consists of the following:

  • A schema (MDSYS derived from Multi-Dimensional System) that defines the storage, syntax, and semantics of the supported geometric (both vector and raster) data types
  • A spatial indexing mechanism for faster querying and retrieval
  • Operators, functions, and procedures for performing spatial analysis and query operations
  • A persistent topology data model for working with data about nodes, edges, and faces in a topology
  • A network data model for modeling and working with spatial networks
  • A GeoRaster data type and associated functions that let you store, index, query, analyze, and deliver raster data

Ninja Topics

by Matthew Robbins | October 2013 | Open Source

This article by Matthew Robbins, author of Application Testing with Capybara, helps us in using Capybara outside Cucumber in bespoke frameworks, within popular test frameworks such as RSpec and explores some alternatives to Capybara's built-in drivers.

It seems appropriate for us to look beyond the basic API and functionality that Capybara offers. You now have all the skills required to automate your application using Capybara, regardless of whether it is a Rails/Sinatra application or a web application written using any other framework.

This article will ensure that you are comfortable using Capybara outside of Cucumber. It will also show how you can access functionality in your chosen driver that is not mapped by Capybara's API and introduce you to some of the other drivers that you may not have encountered.

Specifically, we will cover:

  • Using Capybara outside of Cucumber
  • Advanced interactions and accessing the driver directly
  • Advanced driver configuration
  • The driver ecosystem—some alternative options

Using Events, Interceptors, and Logging Services

by Fabio Mazanatti Nunes William Markito Oliveira | October 2013 | Enterprise Articles Oracle

In this article written by Fabio Mazanatti Nunes and William Markito Oliveira authors of the book, Getting Started with Oracle WebLogic Server 12c: Developer's Guide, we are going to briefly introduce two concepts of Java EE development: interceptors and events. We will also see how to integrate these concepts with WebLogic services. It's a common misunderstanding that these technologies are complex and difficult to use, but after working with examples of this article, it will become clear that they are powerful yet easy to use. Along the way, we will cover WebLogic Server's logging services, which shows us how to configure the framework, how to write messages to it, and how to read them using the administration console.

Routes and model binding (Intermediate)

by Christian Horsdal | October 2013 | Open Source Web Development

This article by Christian Horsdal, author of Instant Nancy Web Development, we take a look at how to handle the other HTTP verbs apart from GET and how to work with dynamic routes such as /custumer/42, where 42 is the customer ID. We will also look at how to work with JSON data and how to do model binding.

In this recipe, we will see the Todo application, which is the running example of the article, take shape. In fact at the end of this recipe, you will have a backend—if hooked up correctly— that works with the canonical JavaScript library todo samples. The downloadable code for this recipe is attached with the backbone.js todo sample.
