While Visual Studio does come with a working version of Microsoft SQL Server for development use, it is sometimes necessary to implement another database solution.
MySQL is arguably the most popular alternative relational database solution, and has brought the power of database-driven software development for no cost.
While the windows installers are less complex than compiling MySQL from source on a Linux system, there are still some details to keep in mind.
In this video, I will show you how to install MySQL Server, MySQL Workbench as your administration tool, and how to run a simple query.

File Management refers to to terms of working with files, manipulating them, changing their names, locations etc. When creating iOS or MAC OS apps, we can use the C-style functions for working with files.
As Objective-C is an object oriented programming language, well use its way, and that will be the NSFileManager class, which has a bunch of utility methods.
[NSFileManager defaultManager] will return us a NSFileManager object that we can further use.
To check if a file exists at a specific path, we use the syntax:
if ([[NSFileManager defaultManager] fileExistsAtPath:filePath])
To change the files location, we use:
[fileManager moveItemAtPath:currentPath toPath:newPath error:nil];
We can provide a NSError object as the last parameter to this function, and then use that to check if the operation involving files got successfully executed. Introduction to File Management in Objective-C](https://i.ytimg.com/vi/ZR5fATD2tG4/mqdefault.jpg)

Now that we have correctly configured our SuspensionManager helper class, we can start populating data into the Application Data container.
We first need to create a variable, and then feed the appropriate container (in this case roaming data) into that variable.
After that, we can start putting key and value pair information into that container, using standard notation:
Container[Key] = Value;
In this video, I will show you how to access and write to the RoamingData object.
