If you were creating a web app from scratch today, what database would you use? Probably the most frequent answer I see to this is Postgres, although there are a wide range of common answers: MySQL, MariaDB, Microsoft SQL Server, MongoDB, etc. Today I want you to consider: what if SQLite would do just fine?
Function pipelines allow you to analyze data by composing multiple functions in SQL and express complex logic in PostgreSQL in a cleaner way.
Looking for a research paper but can’t find a copy in your library’s catalog or popular search engines? Give Internet Archive Scholar a try! We might have a PDF from a “vanished” Open Access publisher in our web archive, an author’s pre-publication manuscript from their archived faculty webpage, or a digitized…
*Couple of weeks ago we have noticed the article getting attention around twitter. As it is using our WMS EOxMaps endpoint we have asked Erin Davis if we could host her idea here. At EOX we endorse brilliant and unique ideas that utilize our tools and data. Thank you for this most interesting contri ...
Notion’s data model enables the product’s most foundational component: blocks. Through blocks, we allow users more flexibility over their information.
The AFR for 2020 dropped below 1% down to 0.93%. In 2019, it stood at 1.89%. That’s over a 50% drop year over year.
A complete list of SQLite releases in a single page and a chronology are both also available. A detailed history of every check-in is available at SQLite version control site .
SQLite strives to be flexible regarding the datatype of the content that it stores. For example, if a table column has a type of "INTEGER", then SQLite tries to convert anything inserted into that column into an integer. So an attempt to insert the string '123' results in an integer 123 being inserted. But if the…

Which means, that to test it, we need some data for recursive queries. This time I took directory listing of my /etc, and loaded it to db:
A comprehensive overview of the best practices for securing access to PostgreSQL databases.
Let's say you have a web app with some database. In your database you have an Invoice model, where you store things you are charging your customers.
Haiying Tang takes you on a tour of LZ$ TOAST, the new column opton compression in PostgreSQL 14, and shows the speed and compression ratio gains.
We just raised a $40M Series B to bring our relational database for time-series to developers everywhere. Learn how we got started and what’s still yet to come.
Twenty years ago today, the first email on the postgis users mailing list (at that time hosted on yahoogroups.com) was sent, announcing the first numbered release of PostGIS. The early history of PostGIS was tightly bound to a consulting company I had started a few years prior, Refractions Research. My first contracts…
This is a bit of a rant but I really don't like software that invents its own query language. There's a trillion different ORMs out there. Another trillion databases with their own query language. Another trillion SaaS products where the only way to query is to learn some random query DSL they made up.
Welcome to acronym city! The Court of Appeal of Brussels has made an interesting ruling. A customer complained that their bank was spelling the customer's name incorrectly. The bank didn't have support for diacritical marks. Things like á, è, ô, ü, ç etc. Those accents are common in many languages. So it was a little…

I'm super enthusiastic about Julia after running this comparison of Julia vs Numpy vs Fortran, for performance and code simplicity.
PlanetScale is the first database designed for developer workflows on top of the technology of the hyperscalers.
Programmers often need to 'filter out' data. Suppose that you are given a database of users where only a small percentage are 'paying customers' (say 5% or less). You can write an SQL query to check whether a given user is indeed a paying customer, but it might require a round trip to your database … Continue reading…
