4 1. Introduction and background The managers of Natura 2000 sites are currently confronted with changes to their areas due to anthropogenic as well climatic impacts. Habitat compositions are changing following a changing climate and modifications in land use. Nature conservation strategies have to understand those changes as in order to be able to react appropriately. In the HABIT-CHANGE the project consortium developed scenarios and indicators that help to describe this change, its drivers and effects. The aim of the project is to evaluate existing management strategies is to provide nature park managers with This technical documentation provides a step-by-step guide how we designed and set up the IT infrastructure for this Decision Support System. See: 2. User Requirements Open Source Software: >Apache Webserver >MySQL database >PHP scripting language It is the most widely used software for the development of Web applications. The Apache Friends project has bundled these software in a package called XAMPP, to make it more comfortable. Everything is pre-configured and ready to use, just download, install and start. There are also versions for several Linux distributions, a Mac OS X beta version first steps of development), as well as a smaller portable version, called XAMPP Portable Lite. up to this date just for Windows) With the Portable Lite configuration it runs from your removable media. You can use it on your USB flash drive or your external hard drive. You can download it here: [4]

5 After the installation is complete, you will find XAMPP under Start Programs XAMPP. Or when you decide to use the portable version, please go to the folder where you unzipped it. e.g. C:\xampplite\xampp-control.exe) You can use the XAMPP Control Panel to start/stop all server and also install/uninstall services. If the Apache Webserver is started green color), type localhost/xampp in a new browser tab. Firefox,Chrome are recommended) to see it online and the status of their components. This project is implemented through the CENTRAL EUROPE Programme co-financed by the ERDF [5]

6 3. Data sets The DSS web application communicates with database tables. As mentioned before a MySQL database is used and needs to be filled. Please download these 4 Excel csv) files Every file contains the data records of a specific database table. respective Habitat, Pressure, Impact and Response ) 4. Database Design and set up Now go to localhost/phpmyadmin. You will see the web database management tool of the MySQL database called phpmyadmin. Click on the Database tab in the main menu. Create a new database by typing habit_change_dss, also define the character encoding with utf8_general_ci. see attached picture) Press the Create button. [6]

7 Select the just created database by choosing habit_change_dss from the left menu. Now the tables of the database have to be generated and filled with the information of the downloaded excel files. important: this example assumes that all excel files are stored in C:\Test) Click on the SQL tab in the main menu: Copy the SQL statements below into the SQL query window see picture) Press the Go button. Do this procedure for every single table. CREATE TABLE habitat habitat_id int not null primary key auto_increment, habitat_level1 smallint, habitat_l1_desc varchar200), habitat_level2 smallint, habitat_l2_desc varchar200), habitat_type char5), habitat_type_desc varchar200) LOAD DATA LOCAL INFILE '/Test/habitat.csv' INTO TABLE habitat FIELDS TERMINATED BY ';' LINES TERMINATED BY '\n'; This project is implemented through the CENTRAL EUROPE Programme co-financed by the ERDF [7]

8 CREATE TABLE pressure pressure_id int not null primary key auto_increment, pressure_code smallint, pressure varchar200), pressure_type varchar50), pressure_subtype varchar50), habitat_level1 varchar50), created_by varchar50) LOAD DATA LOCAL INFILE '/Test/pressure.csv' INTO TABLE pressure FIELDS TERMINATED BY ';' LINES TERMINATED BY '\n'; CREATE TABLE impact impact_id int not null primary key auto_increment, impact_code smallint, impact text, impact_type varchar50), habitat_level1 varchar50), created_by varchar50) LOAD DATA LOCAL INFILE '/Test/impact.csv' INTO TABLE impact FIELDS TERMINATED BY ';' LINES TERMINATED BY '\n'; CREATE TABLE response response_id int not null primary key auto_increment, response_code smallint, response_option text, response_type varchar50), source varchar50), habitat_level1 varchar50), created_by varchar50) [8]

9 LOAD DATA LOCAL INFILE '/Test/response.csv' INTO TABLE response FIELDS TERMINATED BY ';' LINES TERMINATED BY '\n'; The table hpir_chains will be used to store the Habitat-Pressure-Impact-Response hpir-) chains created by the user with the DSS web application. CREATE TABLE hpir_chains hpir_id int not null primary key auto_increment, habitat_id integer, pressure_id integer, impact_id integer, response_id integer, created_by varchar50) With the table habit_members you can define which user will have full access to the database can create chains) and which user will have limited access, can just read the database. The predefined user guest, will automatically have this kind of limited reading role. CREATE TABLE habit_members user_id int not null primary key auto_increment, username varchar50), password varchar50) INSERT INTO habit_members username, password) VALUES 'guest', MD5'guest') INSERT INTO habit_members username, password) VALUES 'user1', MD5'pass1') This project is implemented through the CENTRAL EUROPE Programme co-financed by the ERDF [9]

10 When the table import is done, you will see a database structure like in the picture above. Now the database is ready. When you click browse, you can see the content of each table. 5. Web application The last step is to copy the program files into Apache s Hyper Text Documents" htdocs folder. It is located within your xampp main folder. [10]

11 Please download the program files: That s all, now you can start the DSS web application, and start creating chains: This project is implemented through the CENTRAL EUROPE Programme co-financed by the ERDF [11]
