| Accessing the database. The Swiss Feed Database
is run under PostgreSQL open source database management system. The parameters to
access the database are the following:
|
|
| host name: | talis.ifi.uzh.ch |
| port: | 5432 |
| database name: | tfdb |
|
|
| The login name and password are assigned
by the request to Andrej Taliun or Francesco Cafagna. The database can be accessed from multiple
environments. The easiest approach is to use
pgAdmin that provides a highly developed graphical user interface and is run
on the most of the operating systems. One can also connect to the database from
a command line with 'psql -d tfdb -h talis.ifi.uzh.ch -p 5432 -U your_login_name -W',
using PhP as described in the example
or with Java using the JDBC driver. All connection to the database are via ssl protocol.
The following example illustrates how it can be achieved in Java:
|
| ... |
|
Class.forName("org.postgresql.Driver"); |
|
|
Properties prop = new Properties(); |
|
prop.put("user",your_login); |
|
prop.put("password", your_password); |
|
prop.put("ssl", "true"); |
|
prop.put("sslfactory", "org.postgresql.ssl.NonValidatingFactory"); |
|
Connection conn = DriverManager.getConnection("jdbc:postgresql://" + "talis.ifi.uzh.ch:5432/" +"tfdb", prop); |
| ... |
| Extending the web interface. The first step
is to install Apache2 web server with support of PostgreSQL via php5.
On Ubuntu this is done with the following five commands:
|
| sudo apt-get install apache2 |
| sudo apt-get install php5 |
| sudo apt-get install libapache2-mod-php5 |
| sudo apt-get install sudo apt-get install php5-pgsql |
| sudo /etc/init.d/apache2 restart |
| and, then, all your future web files are found in /var/www/.
The last step is to download and extract the latest
of the application.
