Projects in the cache database

The data transferred into the cache database are always transferred according to a project they belong to. If no projects were added so far the window will appear like shown below. For an introduction see a short tutorial .

To add a new project for the transfer into the cache database, click on the Add project button. In the area below a new entry as shown below will appear. The area on the right shows the number of datasets in the project in the source database together with the date of the last update. To ensure the separation of the data between the projects, DiversityCollection creates a separate schema for every project named Project_[name of the project] together with needed roles, tables etc..

In case there are projects where you do not have access to, this will be indicated as shown below.

In case a project has been renamed in the main database, a button will appear as shown below. The displayed name corresponds to the name in the main database. To see the original name, click on the button.


Before transferring data you have to update the project schema to the latest version, indicated by the appearance of an update button . Click on the button to open a window as shown below. Click on the Start update button to update the schema to the latest version.

After the update the database is ready to transfer data into. 

Besides the restrictions in the source database, you can set further restrictions for this transfer. Click on the button to edit the datawithholding reasons for the data of the project. Click on the button and choose the ranges of the data that should be transferred (see below).

To transfer the data you have 3 options as described in the Transfer chapter.

Afterwards the number and date of the transferred data are visible as shown below.

To inspect the transferred data use the View content button. A window as shown below will open where all tables containing the data of the project are listed.

Click on the button to filter the content. A window as shown below will open. Choose the column for the filter, the operator (e.g. = ) and the filter value (see below).

Now click on the button to add the filter criteria to the table filter. You may add as many criteria as needed (see below). With the button you can clear the filter..

Before you can transfer the data into the Postgres database, you have to connect to the Postgres database and click on the button to establish the project and run necessary updates . After the project is established and up to date, use the button to transfer the data in the Postgres area (see below).

If a project is exported into another Postgres database on the same server, these databases will be listed underneath the Postgres block (see image below). For an overview of all target Postgres databases click on the button.

If the target is placed on the current server, the text will appear in black (see image below). Packages will be listed for the other targets as well.


In the Postgres database you can install packages to adapt the data to any needed format.
