Advanced SQL: Window Functions

By Ami Levin, Trainer, Consultant and Mentor

Window functions are a significant and fundamental enhancement to modern SQL, offering a host of powerful capabilities. They provide access to neighboring rows without the need for subqueries, making it easier to develop higher-performing, more concise solutions. 

In this course, your team will learn various constructs and advanced solution techniques using window functions, as well as how to harness the declarative and composable nature of SQL and its processing order. By the course's conclusion, learners will have gained a comprehensive understanding of the inherent advantages and disadvantages associated with each method.

Advanced SQL for Query Tuning and Performance Optimization

By Dan Sullivan, Data Architect, Data Engineer, Cloud Architect

Poor performance and long-running queries are commonplace, even for skilled SQL programmers. When teams understand fully how databases turn SQL queries into action, they will be better equipped to keep queries fast and efficient. 

In this course, Dan offers strategies to analyze how queries are executed. He also explains the different types of indexes and how to tune queries for each, offers several methods for more efficient joins, and covers how to use partitioning and materialized views for further gains.

Data science and analytics courses:

Advanced SQL for Data Scientists

By Dan Sullivan

SQL is the go-to language for data analysis, and many data scientists are familiar with its basics. But as data sizes grow, it's crucial to go beyond the basics and level up your team’s SQL skills. That's where this course comes in. 

Dan covers table design for large databases, takes a deep dive into indexes, including specialized indexes, and covers query optimization, too. 

The course also covers SQL extensions, like user-defined functions and specialized data types.  These extensions give the flexibility to apply custom business logic and enhance data analysis.

Advanced SQL for Data Science: Time Series

By Dan Sullivan

Time series data presents unique challenges for data scientists, as it encompasses various metrics, user interactions, and sensor-generated information collected over time. However, SQL provides features specifically designed to assist in analyzing time series data. This course teaches how to effectively standardize and model this type of dataset. 

Instructor Dan Sullivan covers essential topics such as windowing, the difference between sliding and tumbling window calculations, and the use of SQL constructs like OVER and PARTITION BY to simplify analysis. Learners will also explore optimization techniques such as indexing, and dig into time series analysis methods like previous time period comparisons, moving averages, exponential smoothing, and linear regression.

Advanced SQL: Logical Query Processing, Part 1

By Ami Levin

This course goes beyond the basics of syntax to unlock a whole new realm of knowledge, shedding light on how relational database management systems process SQL queries and its direct impact on coding practices.

In this course, learners gain the tools to avoid common pitfalls and overcome processing limitations. It also covers advanced JOIN techniques that will elevate query proficiency to new heights, and teaches how to handle missing data effectively, ensuring the integrity of your team’s analysis.

But that's not all. We'll unravel the subtleties of ternary logic, delve into SELECT expression evaluation, and demystify grouping logic. Plus, it will equip your team with the know-how to implement efficient paging and ordering, making it easier to navigate large datasets.

Programming and design courses:

Advanced SQL for Application Development

By Dan Sullivan

In application development, a well-designed relational database is a prerequisite for success. However, a poorly crafted data architecture and inadequately written SQL code can lead to lackluster performance, unreliable services, and scalability challenges. 

With a focus on practicality, this course offers a hands-on learning experience, complete with real-world examples and invaluable lessons. Your team can learn to master the art of building scalable and resilient databases that can seamlessly support any application.

Throughout the course, learners dive into the art of writing optimized SQL for transaction processing, a crucial skill for ensuring efficient data handling. They will:

  • Discover how to leverage the power of indexes to minimize read latency and maximize performance. 

  • Explore the concept of data partitioning and learn how it can revolutionize your application's scalability. 

  • Gain insights into object-relational mapping (ORM) and learn how to respond to common database errors like query timeouts and refused connections, ensuring the reliability and resilience of applications.
