Analysis

^{(The purpose of the analysis is to give as much as possible of the needed information for designing and implementing the task.)}

Overview

There will be singleton class that will provide the connections and communications with the database. There will be entity classes that will correspond to tables in the database

Task requirements

We must decide how we will implement the persistence of the entities to the database. We must design and implement the IDatabaseManager using some of the following approaches or something else :

• Use reflection and the entities property names?
• The entities are dictionaries with appropriate getters and setters?
• Static strings for names?
• Every entity has it's own persist, update, insert, etc methods, that use IDatabaseManager? In that case the database manager will have methods like openConnection and closeConnection...

We must decide if we will have opened connection all the time or for every action to the database we will open a connection.

Task result

The end result will be interface for communication with the database.
