Feed: Planet PostgreSQL. TL;DR: keep your data-layer simple, you'll need the agility it offers when budgets get stretched.Over the past 12 years of helping people run databases for their businesses, I have discovered that there are only 2 financial phases in the lifecycle of a database: Phase 1: Absolute costs are low, thus marginal costs do not matter. Phase 2: Absolute costs are high, thus marginal costs are all that matter. I'm calling this difference between Phase 1 and Phase 2 the "database financial gap." The first hint there is a problem comes from questions about optimizations. Developers & DBAs ... Read More

Feed: Planet PostgreSQL. The one thing I like to do is challenge PostgreSQL - and readers - to the extreme. A while ago I posted about the Beer o'clock. Building Zoé was another interesting example. And at some point I blog about Dancing with the Stars as well. Today it's all about nothing. Empty. Where is all the data gone? A while ago I posted this screenshot on Twitter, and as far as I can tell no one found the correct answer. The screenshot looks like there's nothing. Empty names, schema name, role name, database name, even no data. And yet ... Read More

Feed: AWS Architecture Blog. Many organizations have applications that require Microsoft SQL Server to run relational database workloads: some applications can be proprietary software that the vendor mandates Microsoft SQL Server to run database service; the other applications can be long-standing, home-grown applications that included Microsoft SQL Server when they were initially developed. When organizations migrate applications to AWS, they often start with lift-and-shift approach and run Microsoft SQL database service on Amazon Elastic Compute Cloud (Amazon EC2). The reason could be this is what they are most familiar with. In this post, I share the architecture options to modernize ... Read More

Feed: Neo4j Graph Data Platform. Author: Neo4j Staff. Here is the actual point of a true, native graph database: Real solutions require visualization. When you can see the problem, you can find the solution. And when you can project the problem to your database manager as something it can see, it can find the solution without you having to massively transform your data first. Of course, what you really need to make this happen is the right graph. The right graph The right graph — and there truly is such a thing as “the right graph” — is never terrifically complex.  For ... Read More
