## Background
TECHNICAL FIELD
The present invention relates generally to systems and methods for managing data replication processes on databases, including systems and methods for stopping and initiating data replication processes on databases.
BACKGROUND
Modern organizations rely on databases to store data. Generally, there are software tools that allow organizations to replicate, filter, and transform data from one database to another database. However, there are instances (e.g., maintenance activities) during which replication processes have to be stopped or halted manually, and reinitiated manually. Manually stopping and initiating replication processes can be especially cumbersome as the number of databases involved increases. Therefore, there is a need for a software tool that is able to automatically manage data replication processes across a number of databases.

It infers a function from labeled training data consisting of a set of training examples. Each example is a pair consisting of an input object and a desired output value. A supervised learning algorithm or machine learning algorithm analyzes the training data and produces an inferred function, which can be used for mapping new examples.
