Some embodiments of a system and a method to use a separate process in an interactive computer programming environment as a database have been presented. For instance, both server and client may run in an interactive computer programming environment, such as Read-Eval-Print Loop (REPL) environment. The server may receive data manipulating instructions written in a generic programming language and data from the client. The server can execute the instructions to manipulate the data. The server may further act as a database for the client by maintaining persistence of the data.
