Title:
SQL and Large Language Models: A Marriage Made in Heaven?

Abstract:
With the rise of pre-trained Large Language Models (LLMs), there is now an effective solution to store and use information extracted from massive corpora of documents. However, for data-intensive tasks over structured data, relational DBs and SQL queries are at the core of countless applications. While these two technologies may appear distant, in this talk we will see that they can interact effectively and with promising results. LLMs can help users express SQL queries (Semantic Parsing), but SQL queries can be used to evaluate LLMs (Benchmarking). Their combination can be further advanced, with opportunities to query with a unified SQL interface both LLMs and DBs. We present recent results on these topics and then conclude with an overview of the research challenges in effectively leveraging the combined power of SQL and LLMs.

Title:
Knowledge Graphs, ready to power intelligent systems?


Abstract:

As knowledge graphs become increasingly vital for managing and integrating heterogeneous data, they are also emerging as key components in supporting intelligent systems and enabling advanced data analysis. Their capacity to represent and connect vast amounts of information presents exciting opportunities but also brings significant challenges in ensuring data quality, interoperability, and efficient access at scale. This talk explores approaches to fully leverage the potential of knowledge graphs, positioning them as trustworthy, scalable tools ready to meet the demands of an increasingly data-driven world.

Title:
An Ode to Stateful Dataflow Graphs


Abstract:
Data stream processing is witnessing its prime time due to efforts by database researchers and numerous worldwide open-source communities. While stream processing in the early 2000s was used for computing simple windowed aggregates and joins, stream processors nowadays are used for real-time traffic predictions, fraud detection, event-driven microservices, and even serverless functions. In this talk, I will first outline how streaming systems have changed since the early days of stream processing, and pinpoint the main advances that have led to the widespread adoption of modern stream processors. I will then turn to the ability of stream processors to be “misused” in modern applications based on an important observation: multiple families of data-intensive applications can be modeled as stateful dataflow graphs, which can be automatically scaled and deployed in the Cloud. Are streaming dataflow engines the answer to the quest for a "universal execution engine”  for the Cloud?
