SQL Server for Database Administrators

In this chapter, you'll create your very first database with a set of simple SQL commands. Next, you'll migrate data from existing flat tables into that database. You'll also learn how meta-information about a database can be queried.

Your first database

After building a simple database, it's now time to make use of the features. You'll specify data types in columns, enforce column uniqueness, and disallow NULL values in this chapter.

Enforce data consistency with attribute constraints

Now let’s get into the best practices of database engineering. It's time to add primary and foreign keys to the tables. These are two of the most important concepts in databases, and are the building blocks you’ll use to establish relationships between tables.

Uniquely identify records with key constraints

In the final chapter, you'll leverage foreign keys to connect tables and establish relationships that will greatly benefit your data quality. And you'll run ad hoc analyses on your new database.

Glue together tables with foreign keys

You’ve already used SQL to query data from databases. But did you know that there's a lot more you can do with databases? You can model different phenomena in your data, as well as the relationships between them. This gives your data structure and consistency, which results in better data quality. In this course, you'll experience this firsthand by working with a real-life dataset that was used to investigate questionable university affiliations. Column by column, table by table, you'll get to unlock and admire the full potential of databases. You'll learn how to create tables and specify their relationships, as well as how to enforce data integrity. You'll also discover other unique features of database systems, such as constraints.

A good database design is crucial for a high-performance application. Just like you wouldn't start building a house without the benefit of a blueprint, you need to think about how your data will be stored beforehand. Taking the time to design a database saves time and frustration later on, and a well-designed database ensures ease of access and retrieval of information. While choosing a design, a lot of considerations have to be accounted for. In this course, you'll learn how to process, store, and organize data in an efficient way. You'll see how to structure data through normalization and present your data with views. Finally, you'll learn how to manage your database and all of this will be done on a variety of datasets from book sales, car rentals, to music reviews.

In this chapter, you will deepen your knowledge of handling errors. You will learn how to raise errors using RAISERROR and THROW. Additionally, you will discover how to customize errors.

Raising, throwing and customizing your errors

In this chapter, you will be introduced to the concept of transactions. You will discover how to commit and rollback them. You will finish by learning how to return the number of transactions and their state.

Transactions in SQL Server

This chapter defines what concurrency is and how it can affect transactions. You will learn exciting concepts like dirty reads, repeatable reads, and phantom reads. To avoid or allow this reads, you will explore, one by one, the different transaction isolation levels.

Controlling the concurrency: Transaction isolation levels
