successfully reading and writing to database
move all db code to data access layer

Data access layer (DAL) contains
1. A database class, for encapsulating connection creation,
2. Simple data transfer object (DTO) classes, e.g., Patient.cs, for
working with real objects in the logic layers, and
3. Data access object (DAO) classes, e.g., PatientDAO.cs, for running
queries. DAOs take in DTOs for performing updates to the database, and
return DTOs or collections of DTOs as results of queries.
