1.) I am going to start by assuming that you have a bachelor’s degree in either Computer Science or Information Systems Management. Now that is not absolutely required or mandatory because some companies want you to have a degree in computer science and most would accept a degree in any industry. Even if you don't hav a degree, you cn still build a DBA career as you gather exeprience, so don't feel like you can't become a DVA without a degree.
2. When searching for companies, try to land an IT job at a company that utilizes the SQL Server Database software as the back-end.
Learn the Windows Server operating system and master SQL Server database design and development before you tackle SQL Server Administration.
Note that while becoming a DBA is your ultimate prestigious goal, it may be beneficial for you to start with learning or mastering Relational Database Design, Development, SQL Server Stored Procedures, Views, Indexes, Triggers and Advanced SQL Query Optimization.
These are just some of the things needed to learn on your way to mastering SQL Server Administration, Maintenance and startind your DBA career.
