### The development view of PySD
To represent the architecture of the fragments which made up *PySD*is used a package diagram. In that diagram, it represented the hierarchical architecture of pysd packages excluding the relationship between its modules.
To represent the architecture of the fragments that make up *PySD* a package diagram is used, represented in [PySD development view]. In this diagram, the hierarchical architecture of pysd packages is represented, excluding the relationship between their modules. In [PySD relationships between modules] we can find the relationships between pysd modules.
![PySD development view]
**pysd** is the main package that includes all the others and all the system logic. It is necessary to differentiate between package called pysd and module called pysd. The latter allows the user to interact with the system and has adequate functions to be able to translate a Vensim or XMILE model, and, in addition, to execute the generated translation. However, the XMILE translation is not defined in this document.
**pysd** module interacts with modules in the **py_backend** package. This package has two sub-packages: **vensim** and **xmile**. Vensim package contains all the needed logic to translate Vensim models.
In [PySD relationships between modules] the relationships between the main modules are represented. For clarity, each module has been represented by with name package.
![PySD relationships between modules]
As previously discussed, users interact with **pysd** module. In turn, pysd takes care of translating the Vensim model to the Python model by interacting with vensim2py, which creates the correct Python translation. In this process, vensim2py interacts and uses the functions of the modules: external, utils and builder. To carry out the execution process, pysd uses the functions module.
