This manual describes the process of setting up continuous backups for PostgreSQL databases to safeguard your data from accidental loss in an efficient way.
During past couple of years I have worked on few projects written in GO. I noticed that the biggest challenge developers are facing is lack of constraints or standards when it comes to project layout. I'd like to share some findings and patterns that have worked best for me and my team. For better understanding I'll go through steps of creating a simple REST API.
Hi guys, I’m a Front-End developer. Before there was a time 2 years working CMS Magento, I like CMS Magento because system clean, and architecture database EAV (Entity — Attribute — Value) but I don’t understand why present I’m dev front-end (I don’t know) in the 2-year current. And present I chance comeback working position Back-End that I like.
What are medical databases?Medical Databases serve as an essential part in medical care, which includes the disciplines of research, documentation, patient care and treatment. The medical industry is constantly on the lookout for new medical applications, which would help improve their services. These endeavors are usually done through databases, which store data regarding diseases, diagnosis, treatments, medication, medical devices, medical practices and other pertinent details about medical professionals. With the constant advancements made in technology, these databases have also grown to be more technologically advanced and complex.
I spent the better part of a day moving a project completely off of the ORM we were using (TypeORM). Ever since I started doing web development, I’ve been using some kind of heavy abstraction on top of my database. Whether it’s Mongoose when I used MongoDB, or TypeORM when I decided to move to TypeScript and PostgreSQL. However, it turns out that ORMs and query builders aren’t so great. I used to be that person that thought ORMs and query builders did the job for me, and I used it as an excuse to not learn SQL (which is what everyone tells you NOT to do). Given the tools that exist today, I would wholeheartedly recommend doing it the opposite of how I did if you’re starting off new to these things — write your SQL stuff by hand, or with help from the tools I mention later in the post. It’ll feel really slow at first, but you’ll thank yourself later 😄
Many developers still install a database on their computer and work on it.
It may be a preferable method, but using Docker takes only seconds to set up a database. I used PostgreSQL and Docker in my latest project. As a result, I have achieved efficiency and convenience. I will give you my experience with PostgreSQL and Docker.
Back in the days when MySQL was the undisputed open source database champion, there was a sense that people who took their databases seriously would choose PostgreSQL instead. Everyone else chose MySQL; it was fast and it was easy.
Normal development flow requires continuous patching the production database with local changes normally made automatically by the orm software, this method is not perect but deceptively simple, all we'll use is standard Unix commands, and is good enough for us.
Partitioning is a powerful way to boost your PostgreSQL performance, but it's not a one-size-fits-all. Learn if PostgreSQL partitioning is a solution for you.
In this post, learn how to run a Java Spring Boot application on Azure Kubernetes Service (AKS) and connects to Azure PostgreSQL using Azure AD Pod identity.
PostgreSQL is the jack of all trades when it comes to databases. It brings you all the features you've come to love about SQL plus a bunch of features from Non-SQL databases. Some of these Non-SQL features like the JSONB data type are wonderful and you don't even have to dare flirt with another database. Others are good but not as robust and featureful as other databases.
Docker might be an easy solution as an all-in-one tool for setting up a Local Development Environment. But on the other hand, it eats up a huge portion of your system resources to get up and running, and we hate it when our computer becomes lagging and clumsy.

The OLTP/OLAP split no longer fits how developers build today. Postgres and the lakehouse are now used side-by-side – but stitched together with brittle
Wondering which databases are trending in 2019? We asked hundreds of developers, engineers, software architects, dev teams, and IT leaders at DeveloperWeek to discover the current NoSQL vs. SQL usage, most popular databases, important metrics to track, and their most time-consuming database management tasks. Get the latest insights on MySQL, MongoDB, PostgreSQL, Redis, and many others to see which database management systems are most favored this year.

PostgreSQL is an open-source, object-relational database management
system (ORDBMS) available for all major platforms including Linux, UNIX,
Windows, and OS X. It allows you to add custom functions developed using different programming languages such as C/C++, Java, etc. It is designed to handle a range of workloads, from single machines to data warehouses or Web services with many concurrent users. It is the default database for macOS Server.
Auto-increment is a database feature that generates unique IDs for new rows. It's supported by most RDBMS and can be implemented using different syntax.
What comes to a Python developer’s mind when he needs to write an I/O bound application? Of course async. Why? Usually, because it’s a trend. And I’ve seen this
We use different Continuous Integration tools in our projects. One of them is TeamCity software. A pipeline for TeamCity can be configured easily and has two steps, such as run tests and build a docker image for further deployment. However, I needed to run Postgres before running tests. I made a research, I read the documentation and this article may be useful to close a gap for team city’s documentation.
SQL is very important and many programmers realize this, however, I have found that many more programmers just don't spend much time improving their SQL skills.
