I tried dropping the property before adding it again as a link, it was fine
on DB level I could find it created as required but when populating the
data it shows the season for all Competition records like "#55:-50
<http://localhost:2480/studio/index.html#/database/sport/browse/edit/55:-50>"
which is a dummy record "not found".
Through the documentation it mentions this to have a link created in the
record. But in my case it is so much java process to go through all classes
and properties to fill their values this way. In 1.7.10 version that was
done automatically.
1-1 and N-1 embedded relationships
1-1 and N-1 embedded relationships are expressed using the *EMBEDDED* type.
OClass address = database.getMetadata().getSchema().createClass("Address");
OClass account = database.getMetadata().getSchema().createClass("Account");
account.createProperty("id", OType.INTEGER);
account.createProperty("birthDate", OType.DATE);
account.createProperty("address", OType.EMBEDDED, address);
