I have a gps device that records data e.g. datetime, latitude, longitude

I have an sdk that reads the data from the device. The way the data is read:

A command packet (basically a combination of int values in a struct) is sent to the device. The device responds with the data in fixed size chunks e.g. 64bytes

Depending on the command issued I will get back differect data structs e.g. sending command 1 to the device returns a struct like

struct x
{
 id int,
 name char[20]
}

command 2 returns a collection of the following structs (basically it boils down to an array of the structs - y[12])

struct y
{
 date datetime,
 lat decimal,
 lon decimal
}

I would then want to convert the struct to a class and save the data to a database.

What would be the best way to encapsulate the entire process, preferably using some established design pattern?

Many thanks M
