Data PDX: Kùzu Graph Database Management System
Online via Google Meet

Bio: Semih Salihoğlu is an Associate Professor and a David R. Cheriton Faculty Fellow at University of Waterloo. His research focuses on developing systems for managing, querying, or doing analytics on graph-structured data. His main on-going systems project is Kùzu, which is a new graph database management system that integrates novel storage, indexing and query processing techniques. He holds a PhD from Stanford University and is a recipient of the VLDB 2018 Best Paper and the VLDB 2022 Best Experiments and Analysis Paper awards.

Abstract: In this talk, I will present the Kùzu graph database management system (GDBMS) that we are developing at University of Waterloo. Datasets and workloads of popular applications that use GDBMSs require a set of storage and query processing features that relational DBMSs (RDBMSs) do not traditionally optimize for. These include optimizations for: (i) many-to-many (m-n) joins; (ii) cyclic joins; (iii) recursive joins; (iv) semi-structured data storage; and (v) support for universal resource identifiers. Kùzu aims to integrate state-of-art storage, indexing, and query processing techniques to highly optimize for this feature set. I will start by presenting the overall vision of Kùzu and then talk about the novel join operators in the system that performs joins using compressed factorized representations of intermediate tables. Kùzu is actively being developed to be a fully functional open-source DBMS with the goal of wide user adoption and under a permissible license.

@DAMAPDX Nov. Chapter Meeting "Data Management Maturity" with Melanie Mecca

Presented by Melanie Mecca Director, Data Management Product and Services, CMMI Institute

Data Management Maturity – Why We Need It and How It Can Propel You to DM Leadership

Our industry is continually building capabilities based on its considerable accomplishments over the past decades. Some of the (roughly) sequential milestone markers that most organization share include: data design, data administration, data architecture / warehousing, data quality and governance, MDM, and predictive analytics using both structured and unstructured data.

So why haven’t organizations attained DM perfection? As we know, the data layer in the vast majority of organizations grew project by project, typically to meet specific needs of a line of business. Best practices were not usually shared, useful work products languished in project repositories, etc. – and above all, there was no universal mandate to manage data as a critical corporate asset.

The Data Management Maturity (DMM)SM Model’s primary goals are to accelerate organization-wide DM programs by: providing a sound reference model to quickly evaluate capabilities, strengths and gaps; accelerating business engagement; launching a collaborative vision / strategy; and identifying key initiatives to extend existing capabilities while building new ones – leading to efficiency, cost savings, creativity, and improved data quality.

In this seminar, we’ll address:

An organization’s ability to effectively serve its customers hinges on the availability of current, accurate, and relevant information. The National Information Exchange Model (NIEM) is a community-driven, standards-based approach to exchanging information. Diverse communities can collectively leverage NIEM to increase efficiencies and improve decision-making.

NIEM is a common vocabulary that enables efficient information exchange across diverse public and private organizations. NIEM can save time and money by providing consistent, reusable data definitions and reusable processes. NIEM is available to everyone, including both public and private organizations.

NIEM includes a data model, governance, training, tools, technical support services, and an active community to assist users in adopting a standards-based approach to exchanging data.

What You Will Learn

This session will provide you with a NIEM overview and some practical applications.
