A system and method for creating a graphical program which accesses data from/to one or more of a data source or a data target. The present invention greatly simplifies the task of creating or configuring a graphical program to exchange data with a data source and/or data target. When a user is creating or configuring a graphical program, the user may cause various nodes or icons to be displayed on the display and may connect the various nodes or icons together. If the user desires the graphical program to access data from/to one or more of a data source or a data target, the user may cause to be displayed a data access node in the graphical program. The user may then configure the data access node with location information of one or more of a data source or a data target. For example, the user may provide a URL specifying a location of the data source or the data target. The computer system may then construct execution instructions in response to the graphical program, wherein the execution instructions are executable to access data from/to the one or more of the data source or the data target as indicated by the data access node. The execution instructions may then be executed, wherein the data access node accesses data from/to the one or more of the data source or the data target during execution.
