You will see how a different view can solve complex problems.

This course focuses on teaching you how to leverage SQL Server's key functions to manipulate data effectively. By utilizing these functions, you will gain the ability to transform and process data in order to achieve desired results. The course covers a wide range of topics, including importing databases into SQL Server, understanding different data types in SQL, and exploring various SQL features. Additionally, you will learn how to work with data on the server, as well as explore the functionalities of SQL functions. The course is designed for individuals interested in data science and those looking to enhance their SQL skills for data science purposes. Whether you are a beginner or have some prior experience with SQL, this course offers valuable insights and knowledge to help you master SQL Server's functions for manipulating data effectively.

A database is essential for high-performance applications. Before you begin building a house, it is important to think about where your data will be stored. This will save you time and reduce frustration later. It is easy to find and retrieve information from a well-designed database. When choosing a design, there are many factors to consider. This course will show you how to efficiently store, process, organize, and present data. This course will show you how to use normalization to organize data and how to present data using views. Learn how to manage your data. This knowledge can be applied to many datasets such as book sales, music reviews, car rentals, and car rentals.

Programming SQL scripts requires the ability to handle errors and transactions. Unhandled errors can be very dangerous and cause unexpected situations, such as inconsistency or other problems that could lead to bad business decisions.

This course will help you deal with errors and manage transactions in the case of an error. It will also show you what happens when multiple users interact with the same data. These concepts will be tested using two datasets. The first is based upon bank accounts and the second on an electric bike store.

Learn SQL Server programming at the highest level. First, we will show you how to manipulate datetime data by using temporal exploratory analysis with the Washington DC BikeShare transactional database. Next, we'll show you how to create and update user-definable functions. You will learn the context and best practices of each modular programming tool. In the final chapter, you will learn how to apply your new skills in solving real-world problems. This will include determining the pickup points for each driver's shift and identifying the New York City yellow taxi usage per borough.

This course is designed to help DBAs and database developers overcome challenges in auditing SQL Server databases and maintaining data integrity.
