| 3 | Data Export |
|---|
| 4 | *********** |
|---|
| 5 | |
|---|
| 6 | Regular data exporters (1) collect objects from specific containers, |
|---|
| 7 | (2) iterate over the collected objects, (3) extract and mangle |
|---|
| 8 | information from each object, (4) write the information of each object |
|---|
| 9 | into a row of a CSV file and (5) finally provide the file for |
|---|
| 10 | download. The CSV file is neither stored in the database nor archived |
|---|
| 11 | in the filesystem. (3) and (4) means a flattening of the hierarchical |
|---|
| 12 | data structure, i.e. a mapping of objects to flat relational data to |
|---|
| 13 | be stored in a CSV table. The extracted information must not |
|---|
| 14 | necessarily be based only on static attributes of the collected |
|---|
| 15 | object. The data, finally stored in the CSV file, can also be derived |
|---|
| 16 | from parent or child objects, or dynamically computed by the object's |
|---|
| 17 | methods and property attributes. These methods and properties can |
|---|
| 18 | retrieve information from everywhere in the portal's database. In the |
|---|
| 19 | following we list all exporter classes including two attributes and a |
|---|
| 20 | method description. The `fields` attribute contain the column titles |
|---|
| 21 | of the export file. These are not necessarily only attributes of the |
|---|
| 22 | exported objects. |
|---|
| 23 | |
|---|
| 24 | .. note:: |
|---|
| 25 | |
|---|
| 26 | The list of exported columns usually underlies heavy customizations. |
|---|
| 27 | In the Kofa base package only very few columns are being exported. In |
|---|
| 28 | some Kofa custom packages tons of data are being gathered from |
|---|
| 29 | applicants and students and the number of columns increase accordingly. |
|---|
| 30 | |
|---|
| 31 | The `title` attribute unveils the name of the exporter under which |
|---|
| 32 | this exporter will be displayed in the user interface. The |
|---|
| 33 | `mangle_value()` method shows how some of fields are being dynamically |
|---|
| 34 | computed. |

| 146 | Student Data Exporters |
|---|
| 147 | ====================== |
|---|
| 148 | |
|---|
| 149 | When starting a Student Data Exporter in the Data Center all student |
|---|
| 150 | records will be taken into consideration, no matter what or where a |
|---|
| 151 | student is studying. The exporter can also be started 'locally' at |
|---|
| 152 | various levels in the academic section. Starting one of the exporters |
|---|
| 153 | e.g. at faculty or department level means that only the data of |
|---|
| 154 | students are exported who study in this faculty or department |
|---|
| 155 | respectively. The exporter can also be started at certificate level. |
|---|
| 156 | Then only the data of students, who are studying the named study |
|---|
| 157 | course, will be taken into account. At course level the data of those |
|---|
| 158 | students are being exported who have attended or taken this specific |
|---|
| 159 | course. |
|---|
| 160 | |
|---|
| 161 | Student Data Exporter can be further configured through a |
|---|
| 162 | configuration page. Search parameters like the student's current level, |
|---|
| 163 | current session and current study mode can be set to filter sets of |
|---|
| 164 | students in order to decrease the size of the export file. The set of |
|---|
| 165 | filter parameters varies and depends on the 'locatation' from where |
|---|
| 166 | the exporter is called. A completely different set of filter |
|---|
| 167 | parameters is provided for courses. In this case the session and level |
|---|
| 168 | can be selected when the course was taken by the student. |

| 229 | used for reimport, or more precisely for backing up and restoring |
|---|
| 230 | data. The following 'special' exporters are made on request of some |
