Knowledge policy refers to a set of guidelines, principles, and practices that govern the creation, dissemination, and utilization of knowledge within an organization, community, or society. These policies are designed to ensure that knowledge is effectively managed and leveraged to enhance decision-making, innovation, and overall organizational performance. Below are some key components and considerations related to knowledge policy: 1. **Knowledge Management**: This involves strategies for capturing, storing, sharing, and utilizing knowledge assets.

nodejs/sequelize/raw/parallel_update_async.js by
Ciro Santilli 37 Updated 2025-06-17 +Created 1970-01-01
nodejs/sequelize/raw/parallel_update_worker_threads.js contains a base example that can be used to test what can happen when queries are being run in parallel. But it is broken due to a
sqlite3
Node.js package bug: github.com/mapbox/node-sqlite3/issues/1381...nodejs/sequelize/raw/parallel_update_async.js is an
async
version of it. It should be just parallel enough to allow observing the same effects.This is an example of a transaction where the SQL READ COMMITTED isolation level if sufficient.
These examples run queries of type:
UPDATE "MyInt" SET i = i + 1
Sample execution:which does:
node --unhandled-rejections=strict ./parallel_update_async.js p 10 100
- PostgreSQL, see other databases options at SQL example
- 10 threads
- 100 increments on each thread
The fear then is that of a classic read-modify-write failure.
But as www.postgresql.org/docs/14/transaction-iso.html page makes very clear, including with an explicit example of type
UPDATE accounts SET balance = balance + 100.00 WHERE acctnum = 12345;
, that the default isolation level, SQL READ COMMITTED isolation level, already prevents any problems with this, as the update always re-reads selected rows in case they were previously modified.Since in PostgreSQL "Read uncommitted" appears to be effectively the same as "Read committed", we won't be able to observe any failures on that database system for this example.
nodejs/sequelize/raw/parallel_create_delete_empty_tag.js contains an example where things can actually blow up in read committed.
It seems there might be a misunderstanding or typo, as "Albert Marque" does not refer to any widely recognized individual or concept in popular knowledge up until October 2023. If you meant "Albert Marques," it could refer to various people, or you may be referring to a specific context (like literature, film, etc.).
Alberto O. Mendelzon was a prominent figure in the field of computer science, particularly known for his contributions to database theory and relational databases. He was a professor at the University of Toronto and made significant advancements in areas such as query languages and data modeling. Mendelzon is also known for his work on the foundations of databases, particularly involving the relational model and its applications. His research helped shape our understanding of how data can be structured, queried, and manipulated in databases.
Albert Schweitzer (1875–1965) was a German-French theologian, philosopher, physician, and Nobel Peace Prize laureate. He is best known for his work in several fields including theology, music, and medicine, as well as his philosophy of "Reverence for Life," which promotes an ethical approach to living that emphasizes respect for all living beings.
The Aleutian Ridge is a geological feature that is part of the Aleutian Islands in Alaska, USA. It is a part of the Pacific Ring of Fire, characterized by a chain of volcanic islands and underwater mountains formed by tectonic activity. The Aleutian Ridge is essentially a long, arc-shaped structure that stretches from the Kamchatka Peninsula in Russia to the southern coast of Alaska, forming a significant part of the boundary between the North American and Pacific tectonic plates.
Alexander Aitken (1895–1967) was a notable Scottish mathematician known for his work in various areas, particularly in numerical analysis and statistics. He made significant contributions to interpolation, approximation theory, and the theory of numerical methods. Aitken is also recognized for developing the Aitken's delta-squared process, which is a method used to accelerate the convergence of sequences.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
