Web 2.0 Access Control Best Practices – Part 1So - you are wrapping up development of yet another Web app. The database is in place, CRUD functions are working, user interface and reports have been signed off. Now your thoughts are turning to access control. Just enough time to splice in that trusty user authentication and roles module, make a few tweaks and move on to the next project. Wait! Do you really want to contribute yet another authorization stovepipe to the growing forest? We all curse the proliferation of authentication and authorization “solutions” on the Web. Yet we continue to treat access control as an after thought.
Developers accept the benefits of adopting third-party solutions for common functions such as data storage, cryptography, numerical analysis, parsing, etc., yet continue to roll their own application access control solutions. Why? The disadvantages of RYO are obvious: application-specific user accounts and passwords proliferate, each application reinvents how roles should be implemented -- perhaps even a language for specifying access constraints -- and, if integration with an external authentication framework is required, each application must implement interfaces to the drivers. This is irritating to our users, a headache for those who administer the applications, and costly to maintain.
In this article we develop a set of Web 2.0 best practices for “outsourcing” the access control problem. Following these practices produces applications that readily integrate into an organization’s existing access control infrastructure, and simplifies application development and maintenance.
Examples are based on DACS (http://dacs.dss.ca) – the Distributed Access Control System. DACS is a mature, lightweightEasy Track User GuideEasy Track is Micrograms’ new record keeping and assessment system. It is easy to set up, easy to maintain, and easy to use. It is designed for use in a network environment where its many features will be fully appreciated. But, it easily can be used to keep student records on a single stand-alone computer as well. Tech staff will notice Easy Track dramatically reduces annual setup time for Micrograms software. No more reentering student names annually or making multiple class files for a single teacher!
Teachers will appreciate that options for all Micrograms programs can be set with Easy Track, and that student data from all Micrograms programs can be viewed, graphed, analyzed, and printed from within Easy Track. Individual student performance and growth can be compared with those of the class, grade, or other student groupings.
Educators also will like Easy Track’s ability to compare group to group performance and growth, so they can analyze various groups’ experience with Micrograms programs from No Child Left Behind perspectives.
The basic idea of Easy Track is that all Micrograms programs use the same database, the Micrograms Data Folder. You enter a student’s name in Easy Track once when she/he enters kindergarten and take it out when the child is no longer a student at the school. Each year you use Easy Track to quickly assign students to their new class groups.
All Micrograms programs are pointed at the Micrograms Data Folder and pick up their class files from there.

GPS Pupils’ guide Introduction to the Global Positioning System Finding location If you look at a map of the world in an atlas, the planet will be covered with a series of grid lines. These grid lines measure latitude and longitude, which is a positioning system used to measure location. In the past, to calculate your location using these numbe was a long mathematical process. Today, however, the easiest way of calculating your latitude and longitude is to use a hand held GPS (Global Positioning System) unit. GPS data is crucial to the GLOBE Programme. You need to know your precise location when you collect data so that your position can be accurately pinpointed, wherever you are on the globe. However, the GPS is not entirely accurate: it has an in-built error which mea that if you were to take just one reading, there is a possibility that it would

As you work through it, you will create a sample database and some tables, and then interact with the database by adding, retrieving, deleting, and modifying information in the tables. During the process of working with the sample database, you will learn the following things:
• The basics of the SQL language that MySQL understands. (If you already know SQL from having used some other RDBMS, it would be a good idea to skim through this tutorial to see whether MySQL's version of SQL differs from the version with which you are familiar.)
• How to communicate with a MySQL server using a few of the standard MySQL client programs. As noted in the previous section, MySQL operates using a client/server architecture in which the server runs on the machine containing the databases and clients connect to the server over a network. This tutorial is based largely on the mysql client program, which reads SQL queries from you, sends them to the server to be executed, and displays the results so that you can see what happened. mysql runs on all platforms supported by MySQL and provides the most direct means of interacting with the server, so it's the logical client to begin with.
