Fromandto

Fromandto is a compound term used in various technical contexts to indicate a relationship or mapping between a starting point and an ending point. It is not a single standardized concept, but rather a label that appears in different domains as either a descriptive idea or a fixed identifier.

In data processing and modeling, fromandto often describes a mapping from a source value or type to a destination value or type. In databases and data schemas, it can represent pairs such as origin and destination, or source and target, stored in a table or used in a join. In graph theory and network representations, an edge may be described by a from node and a to node, signaling directionality. In logistics, routing, and workflow design, fromandto captures the essential notion of where something starts and where it ends.

Naming and usage conventions for fromandto vary by language and project. Some implementations use a single identifier, while others employ two separate fields named from and to, or more explicit alternatives such as origin and destination, source and target, or start and end. When choosing names, consider potential conflicts with reserved keywords and strive for clarity within the given domain.

Because fromandto is not a formal standard, its exact meaning depends on context. It is best understood by examining domain-specific documentation or code comments that define what constitutes the source and destination in that particular setting.
