In software development, when software has been forked or uses a chain of libraries/dependencies, upstream refers to an issue that occurs in software related to the chain. It is the direction that is toward the original authors or maintainers of software .
This database acts as a data warehouse for the organization and also stores information regarding the relationships among its assets. [2] The CMDB provides a means of understanding the organization's critical assets and their relationships, such as information systems, upstream sources or dependencies of assets, and the downstream targets of ...
For example, a patch sent downstream is offered to the developers or maintainers of a forked software project. If accepted, the developers or maintainers will include the patch in their software fork, either immediately or in a future release. For contrast, see Upstream (software development), code sent toward the original development team.
Dependency theory is a subfield of database theory which studies implication and optimization problems related to logical constraints, commonly called dependencies, on databases. The best known class of such dependencies are functional dependencies , which form the foundation of keys on database relations .
The actors act as vertices and the associations act as edges. Each actor T is linked to its upstream and downstream actors in the data flow. An upstream actor of T is one that produced the input of T, while a downstream actor is one that consumes the output of T. Containment relationships are always considered while creating the links.
The core of the challenge is due to the fact that data quality has no intrinsic value. It is an enabler of other processes and the true benefits of effective data management are systematic and intertwined with other processes. This makes it hard to quantify all the downstream implications or upstream improvements.

A data dependency in computer science is a situation in which a program statement (instruction) refers to the data of a preceding statement. In compiler theory , the technique used to discover data dependencies among statements (or instructions) is called dependence analysis .
