Naming rules for databases
Database names are subject to the standard Cypher restrictions on valid identifiers. See Cypher Manual → Naming rules and recommendations.
Naming rules for databases are as follows:
Length must be between 3 and 63 characters.
The first character of a name must be an ASCII alphabetic character.
Subsequent characters must be ASCII alphabetic or numeric characters, dots or dashes;
Names cannot end with dots or dashes.
Names are case-insensitive and normalized to lowercase.
Names that begin with an underscore and with the prefix
systemare reserved for internal use.
It is possible to create an alias to refer to an existing database to avoid these restrictions. For more information, see Creating database aliases.
