Server Configuration Tuning in PostgreSQL

by Gregory Smith | October 2010 | Open Source

The main tunable settings for PostgreSQL are in a plain text file named postgresql.conf that's located at the base of the database directory structure. This will often be where $PGDATA is set to on UNIX-like systems, making the file $PGDATA/postgresql.conf on those platforms.

This article by Gregory Smith, author of PostgreSQL 9.0 High Performance, mirrors the general format of the official documentation's look at these parameters at http://www.postgresql.org/docs/current/static/runtime-config.html. However, it is more focused on guidelines for setting the most important values, from the perspective of someone interested in performance tuning, rather than describing the meaning of every parameter. This should be considered a supplement to rather than a complete replacement for the extensive material in the manual.

Displaying Data with Grids in Ext JS

by Colin Ramsay Shea Frederick Steve 'Cutter' Blades | October 2010 | AJAX Open Source

The grid is, without doubt, one of the most widely-used components of Ext JS. We all have data, and this needs to be presented to the end user in an easy-to-understand manner. The spreadsheet (a.k.a. grid) is the perfect way to do this—the concept has been around for quite a while because it works. Ext JS takes that concept and makes it flexible and downright amazing!

In this article by Shea Frederick, Colin Ramsay, Steve 'Cutter' Blades, and Nigel White, authors of the book Learning Ext JS 3.2, we will be:

  • Using a GridPanel to display structured data in a user-friendly manner
  • Reading data from the server (which provides the data from a database) to display in the grid

NHibernate 3.0: Working with the Data Access Layer

by Jason Dentler | October 2010 | .NET Cookbooks Open Source Web Development

This article series by Jason Dentler, author of NHibernate 3.0 Cookbook, shows how to build a flexible, extensible data access layer based on NHibernate and its many query APIs. There are two styles of data access layer common in today's applications. The first recipe shows the beginnings of a typical data access object. The remaining recipes show how to set up a repository-based data access layer with NHibernate's various APIs.

In these articles we will cover the following topics:

  • Transaction Auto-wrapping for the data access layer
  • Setting up an NHibernate repository
  • Using Named Queries in the data access layer
  • Using ICriteria in the data access layer
  • Using Paged Queries in the data access layer
  • Using LINQ specifications in the data access layer

Of these the first two are dealt with in this article.
