loading, by the second descendant loader into the execution environment, a second plugin and a second set of one or more libraries needed to complete a second operation;

wherein a first type comprised within the first set of one or more libraries and a second type comprised within the second set of one or more libraries (a) cannot be loaded by a same loader into the execution environment and (b) can be loaded into the execution environment using different loaders;

invoking a first method of the first plugin, the first method comprising instructions for completing the first operation; and

invoking a second method of the second plugin, the second method comprising instructions for completing the second operation.

11 . The one or more non-transitory computer-readable media of claim 10 , wherein the operations further comprise:

loading, by the ancestor loader, a plugin interface,

wherein the plugin interface is implemented by at least one of (a) the first plugin or (b) the second plugin.

12 . The one or more non-transitory computer-readable media of claim 11 :

wherein the plugin interface declares an abstract method;

wherein the first method (a) implements the abstract method and (b) is invoked through the plugin interface; and

wherein the second method (a) implements the abstract method and (b) is invoked through the plugin interface.

13 . The one or more non-transitory computer-readable media of claim 10 , wherein the first method comprises instructions for extracting a first data set from a first data source, and wherein the second method comprises instructions for extracting a second data set from a second data source.

14 . The one or more non-transitory computer-readable media of claim 13 , wherein the operations further comprise:

loading, by the ancestor loader into the execution environment, a standard data model, wherein the standard data model is a generic data model;

invoking, a third method of the first plugin, the third method comprising instructions for converting the first data set from a first data model into the standard data model; and

invoking, a fourth method of the second plugin, the fourth method comprising instructions for converting the second data set from a second data model into the standard data model.

15 . The one or more non-transitory computer-readable media of claim 10 , wherein the first descendant loader is a sibling of the second descendant loader.

16 . A system comprising:

at least one device comprising one or more hardware processors;

the system being configured to perform operations comprising:

instantiating a loader type to create a first descendant loader that is a first descendant of an ancestor loader;

instantiating the loader type to create a second descendant loader that is a second descendant of the ancestor loader;
