Creating and deleting object hierarchies

let's assume you want to create grandfather, father and grandchild in a "person" entity to fill the "father" property for the grandchild, you need the dataid of the father record you can now first save the father using a save, use the returned guid to create the father with the next save call, and so on in one step , you do this using a saveall if no entry with the dataid passed in as a parameter exists yet, a new record is created! this also works to create a dependent record in this one query! example entity "person" with the entityid ff5f6566 d02c 4040 9016 cd222aaff0ee has a property custom 001 name and a property custom 002 father for the sake of clarity, we store the relationship as text in the names we use random, newly generated values ​​as dataids this works in various programming languages, for example, like this c# guid newguid(); java uuid newguid = java util uuid randomuuid(); php $newguid = uniqid(); typescript const newguid = uuidv4(); { 	"items" \[ 	 { 	 "entityid" "ff5f6566 d02c 4040 9016 cd222aaff0ee", "dataid" "af92a7a0 e6a2 4237 a33c 5a87dd444fad" "custom 001" "großvater" 	 } ,{ 	 "entityid" "ff5f6566 d02c 4040 9016 cd222aaff0ee", "dataid" "4e609b9b 37c4 43aa 86ce 67e8377e8afa" "custom 001" "vater", "custom 002" "af92a7a0 e6a2 4237 a33c 5a87dd444fad", 	 	 } 	 ,{ 	 "entityid" "ff5f6566 d02c 4040 9016 cd222aaff0ee", "dataid" "af92a7a0 e6a2 4237 a33c 5a87dd444fad" 	 "custom 001" "enkel", "custom 002" "4e609b9b 37c4 43aa 86ce 67e8377e8afa" 	 } 	] } this entire hierarchy can also be deleted using a saveall, in which all entries are set to " isactive" = 0 the presence of a "child" may prevent the deletion of a "father" in this case, the order of the records must be reversed the child is at the top, the grandfather at the bottom { 	"items" \[ 	 { 	 "entityid" "ff5f6566 d02c 4040 9016 cd222aaff0ee", "dataid" "af92a7a0 e6a2 4237 a33c 5a87dd444fad" 	 "isactive" 0, 	 }, 	 { 	 "entityid" "ff5f6566 d02c 4040 9016 cd222aaff0ee", "dataid" "4e609b9b 37c4 43aa 86ce 67e8377e8afa" "isactive" 0, 	 }, 	 { 	 "entityid" "ff5f6566 d02c 4040 9016 cd222aaff0ee", "dataid" "af92a7a0 e6a2 4237 a33c 5a87dd444fad" "isactive" 0, 	 } 	] }
