2007-10-06 Saturday

I'm doing some development this evening on a small Open Source project that I'm planning to release - and I'm comparing the implementation between a PostgreSQL and a MySQL implementation.

Whereas PostgreSQL supports the common RDBMS concept of a SEQUENCE - MySQL does not (at least for the version I'm running: mysql Ver 14.12 Distrib 5.0.24a). However, MySQL Forge has a suggested workaround.
"MySQL Forge is a place for the MySQL user and developer community to contribute content, suggestions, code, projects, and other MySQL-related goodies."


A better way to handle this would be as an abstraction layer - such as implemented by a library (e.g. ADOdb for PHP and Python).


"
* Designed for speed. It is probably the fastest open source database abstraction library available for PHP. See benchmarks.

* Provides extensive portability support such as date and type-handling and portable schema creation. See portable sql tips

* Support many enterprise features such as database backed sessions (with session expiry notification), SQL code generation, pivot tables, SELECT LIMIT emulation for all databases, performance monitoring.

* Easy to learn, especially if you have Window's programming experience, as it uses many ADO conventions.

* Extensive QA, every release is unit-tested on Access, MySQL, PostgreSQL, MS SQL, Oracle 9.

* Mature, continiously developed since August 2000. Has a large community of users.

* Very reasonable licensing terms (BSD). This means that you can incorporate (and even compile) it into your software applications royalty-free without asking the author's permission, provided you include license.txt in your release. Also dual-licensed (Lesser GPL).

I've made some decisions in the last week on adopting some new Open Source tools for a client engagement:

TikiWiki

Pros:

+ Wiki
+ Forums
+ Newsletters
+ Blogs
+ Articles
+ Link Directory
+ Community development of 200+ plugins

Cons:

- I liked MediaWiki's Wiki Syntax better




Flyspray: Task / Bug / Risk / Issue Tracking System

Pros:

+ Clean, Simple, Intuitive User Interface
+ Customizable (e.g. Status, Task, Category)
+ Support for multiple projects

Cons:

- Not yet integrated with webSVN
- Not yet integrated with Subversion
- Doesn't support explicit component association with a bug / task entry




Hudson: Extensible continuous integration engine

Pros:

+ Clean, Simple, Intuitive User Interface
+ Simple configuration
+ User Interface is a core component of the application
+ Supports Ant or Maven build processes
+ Supports execution of Unit Tests
+ Email notification on build failure
+ Scheduled builds - with Source Code Management integration with Subversion

Cons:

- TBD?

Apache JMeter is a 100% pure Java desktop application designed to load test functional behavior and measure performance.


FunkLoad is a functional and load Web tester whose main use cases are functional testing of Web projects (and thus regression testing as well), performance testing, load testing (such as volume testing or longevity testing), and stress testing. It can also be used to write Web agents to script any Web repetitive task, like checking whether a site is alive.

WebLOAD is a load and stress testing tool that is sponsored by RadView. It can load-test any Internet application, including applications that use Web 2.0 and AJAX. Screenshots

WAPT 4.0 is a load and stress testing tool for websites and web-based applications. It uses a fully customizable set of virtual users to simulate a real-life load.
