First-rate PostgreSQL Coders, Professionals for Hire in Ukraine

PostgreSQL is a complete SQL database with a large list of features and a huge number of people around the world who use and develop this database. Unlike another free database: MySQL, the development of which was initially oriented on the Web, the development of PostgreSQL was oriented to use in complex applications. That’s why the emphasis has always been on reliability, availability of advanced functionality and compliance with standards. This can also be used in web applications where this DBMS shows consistently excellent results, with better scalability and customization. PostgreSQL is an object-relational database management system (ORDBMS) based on POSTGRES, Version 4.2, which was developed at the Berkeley Scientific Computer Department of the University of California. The word “object-relational” means the possibility of using some of the functionality associated with object-oriented programming, for example, such as inheritance.

Questions and Answers related to PostgreSQL Development

Why do developers like Postgres more than MySQL?

“In UI world there’s a thing called principle of least surprise / principle of least astonishment. Basically, things reasonably expected to work should work in reasonably expected way and avoid astonishing user. SQL can also be considered a UI of a peculiar sort. When I was shortly exposed to MySQL, I had to work with all sorts of legacy or otherwise surprising gotchas, quirks and limitations that simply should have been eliminated from MySQL, but weren’t. That was annoying.”

What are views in PostgreSQL?

“Views in SQL are a means of treating complex queries in the same way as “ordinary” tables. These are most commonly referred to as “views”. Most databases allow for declaring them using CREATE VIEW my_view as select. These stored views are then part of the catalog and can be referenced by name just like tables. Some databases (including PostgreSQL) even allow for updating them under certain circumstances…”

Can you save an actual JSON into PostgresSQL using Sequelize?

“Yes, you can use JSON and JSONB (the binary compressed form which is likely what you want) both with PostgresSQL and Sequelize. The docs lay out how to use each both for storing and for accessing data. Sequelizer is an ORM and as such if your json represents an entity or model, then you will save that entity by creating the entity with the properties contained in the json to be able to save it in the database.

Can a PostgreSQL database instance support petabytes of data?

“Not possible in practice. 1PB require 250 hard disks a 4 TN (I have no idea how big disks are nowadays) and that is without any redundancy. Connecting so many devices is difficult in itself. And you get a single point of failure and low performance and so on. Consider Greenplum, which is an open source scale-out transactional database build on Postgres…”
