18. The system of claim 17 , wherein operations of inserting the sequence of tokens comprise: allocating a body block associated with the token; writing the sequence of tokens to the body block of the token; test generating a second execution tree based on the sequence of tokens, the second execution tree including a second plurality of nodes; and linking the body block to a head block associated with the token based on a successful test generation of the second execution tree.
17. The system of claim 7 , wherein the operations further comprise executing one or more nodes of the execution tree associated with inserting a sequence of tokens into a token of the token database, the token being one of a cluster token and a derived token, the cluster token referencing one or more instance tokens that conform to one or more conditions associated with the cluster token, the derived token referencing one or more instance tokens that are derived or calculated according to code associated with the derived token.
