Download a database or datasets (preferably from http://nexus.openlca.org/).
Option 1 (for databases only) - Open openLCA and richt-click into the navigation bar and select restore database (works only with *.zolca files). Each databse restore will result in a seperate database in the openLCA navigation window. For *. zolca files, this option 1 is quicker than option 2.
Option 2 - Open openLCA and richt-click into the navigation bar and select new database. Insert a database name and select a database type as well as database content and finish. Right-click on the database and click on import. Navigate through the import dialogue.
Validate a database
Upon importing a database (or datasets) you may want to validate your database to assure that all interlinkages within a database are set correctly: https://ask.openlca.org/18/how-to-validate-a-database-in-openlca
Please note that databases can be quite large (several GB). Depending on the configuration of your PC you may want to change the location of your openLCA databases https://ask.openlca.org/20/how-to-change-the-folder-in-which-openlca-saves-databases
