Welcome! Hello and welcome. My name is Marius, and I am very, very happy that you decided to join me. MTA, Windows Seven Administration Fundamentals I am again very, very happy and excited that we are going to talk about service. In this lecture, I’ll go over three major aspects of COVID. What is this training all about? Who am I? certificates in it. The first point is: what is this training all about? We are going to talk about Windows 7. We will COVID Windows Seven 2008 and 2012….

How to use Windows Server 2012 as a Back up server (NAS) Hi. Windows Server 2012 essentials I am really impressed by this application, and I want to show you how I set it up here in my network and what you can achieve with it. I was looking for another solution. I wanted to have something that could back up my files and send them to the cloud as well. I was looking at, of course, the Nas service. There are numerous options available. I’m a Microsoft guy. Really?…

Permissions – lab Let’s share some drives and folders. Let’s start on the server. What we want to achieve is, let’s say, Mike, right? That’s the name we gave it. Let’s say he has a lot of files, and he asks the administrator, “Can I have a place on your server, please?” And he said, “Yeah, whatever. I can do that for you.” So you go into the reword. In most cases, you would have a dedicated hard drive. We will use the C drive for a small company, and…

What to expect in this section This section is really important. We are going to talk about Active Directory, something that you really need to know if you want to work with Microsoft services. We will set it up from scratch. Add a PC to the domain, discuss group permissions, and go over everything you need to know if you want to work with Active Directory. Active Directory Infrastructure Windows Server. Active Directory, if you ask me. Can you name one topic that is really important? If I want to…

Tables Welcome back. In this video, we’re going to start with the creation of tables. But first, we’re going to create a new database. There are two ways we can create a database in SQL Server Management Studio. We can use the graphical user interface or we can write the Transact SQL script ourselves. So, in the Object Explorer, right-click on Databases and select New Database. The following window opens. The first thing we need to specify is a name for the database. We’re going to name this database fundamental….

Normalization Normalization is the process of structuring a relational database in order to improve data integrity and reduce data redundancy. So there are basically two main reasons why we would want to normalise a database. The first one is to improve data integrity by creating rules for our data and enforcing these rules. The second one is to reduce data redundancy by splitting tables into smaller logical units and creating relationships between them. Imagine you have a customer table storing the name, date of birth, email, and address information of…

Querying Databases – Joins Hi, welcome back. In this video, we’re going to combine data from multiple tables using joins. Earlier in this course, we covered the process of normalising a relational database. We saw that this process involves breaking down tables into smaller logical units or entities. As a result of this, the data no longer resides within one table. So in order to get all the data, we have to combine it by relying on the relationships that are formed during the normalisation process. These relationships are formed…

Querying Databases – Ordering Welcome back. In this video, we’re going to look at ordering data using Transact-SQL. Data within a table can be physically sorted and stored in one specific way, and that completely depends on the clustered index key columns. These are, by default, the primary key columns. The problem is, we don’t always want to retrieve data in that specific way. Say we have a student’s table in which the student ID is the primary key column. This means that the data is physically sorted and stored…

Querying Databases Welcome back. In this video, we’re going to start with querying databases, which means we’re going to request information from the database using Transact-SQL. If we head over to the Object Explorer, expand the Databases node, select the North Wind database, and expand it, you’ll see all the objects that are in this database. For now, we’ll focus only on tables; as you can see, the alt table name starts with DBO, which stands for Database Owner. This is the default database schema. A schema is basically a…

Introduction to T-SQL DQL is used for querying or selecting data from a database. This involves the famous select command; with which we can get data or a subset of data from a database. Secondly, we have the data manipulation language, or DML. This is a subset of transact-SQL commands that are used for manipulating data in a database. The most common DML commands are Insert, which is used for inserting new rows into a table or view. Update, which is used for updating columns in a table or view….
