Book 1 : Are you thinking about learning SQL, but not sure where to start? Big data is prevalent now, with more data than we ever dreamed possible being made available . And all that data needs to be stored in such a way it can be easily accessed. That's where databases and SQL come in, providing the means to manage and interpret data easily. SQL is the go-to language for database management, the most reliable and widely used, and it's showing no signs of losing its popularity. This SQL guide for beginners covers all the basics you need to know about working with data and databases. The book is divided into six parts and includes instructions on downloading a sample database to work with throughout. If you are interested in learning SQL, this is the best place to begin and set yourself on course to become a master SQL programmer. Book 2 : Do you use SQL at work or at home, and want to learn how to use the right functions and queries to extract the relevant details in the database? Do you want to learn how to generate the right views and more? If you answered yes, then you are in the right place. Many companies collect information from different sources, and use that information to improve their revenue. It is difficult to work with large volumes of data, but companies have to learn how to collect that information in data warehouses or databases. Only when the data is stored can it be analyzed and used to improve business decisions. Book 3 : Many companies worldwide suffer from one fundamental problem, and that is the inefficient functioning of their databases. While many know of database tuning and work to cover that aspect, professional database developers, managers, and administrators always miss one thing: optimizing their queries to save maximum time and cost and provide the query efficiently.
