Chapter 3. A Logging Library

In this chapter, we will try to create a logging library that will enable an application developer to log information to a media (file, network, or database) during program execution. This would be a critical library that the developer would be able to use for audit trail (domain pre-requisite) and code instrumentation (from a debugging and verification stand-point). We will design and implement this library from scratch, and make it available as an API to the end developer for consumption.

During the course of this chapter, as a reader, you will learn to leverage strategy pattern, factory method pattern, template pattern, singleton and prototype patterns to do the following:

  • Writing data to a file stream
  • Creating a simple Data Access Layer (DAL) using ADO.NET
  • Writing data to an SQLite database
  • Writing data to a network stream using the System.Net API
  • Handling concurrency
  • Threads
