I understand the workings of OO Programming but have little practical experience in actually using for more than one or two classes. When it comes to practically using it I struggle with the OO Design part. I've come to the following case which could benefit from OO:
I have a few sets of data from different sources, some from file, others from the internet through an API and others of even a different source. Some of them are quite alike when it comes to the data they contain and some of them are really different. I want to visualize this data, and since almost all of the data is based on a location I plan on doing this on a map (using Folium in python to create a leafletjs based map) with markers of some sort (with a little bit of information in a popup). In some cases I also want to create a pdf with an overview of data and save it to disk.
I came up with the following (start of an) idea for the classes (written in python to show the idea):
class locationData(object):
# for all the location based data, will implement coordinates and a name
# for example
class fileData(locationData):
# for the data that is loaded from disk
class measurementData(fileData):
# measurements loaded from disk
class modelData(fileData):
# model results loaded from disk
class VehicleData(locationData):
# vehicle data loaded from a database
class terrainData(locationData):
# Some information about for example a mountain
class dataToPdf(object):
# for writing data to pdf's
class dataFactory(object):
# for creating the objects
class fileDataReader(object):
# for loading the data that is on disk
class vehicleDatabaseReader(object):
# to read the vehicle data from the DB
class terrainDataReader(object):
# reads terrain data
class Data2HTML(object):
# puts the data in Folium objects.
Considering the data to output I figured that each data class render its own data (since it knows what information it has) in for example a render() method. The output of the render method (maybe a dict) would than be used in data2pdf or data2html although I'm not exactly sure how to do this yet.
Would this be a good start for OO design? Does anybody have suggestion or improvements?
