This means if you want transaction support you are out of luck. Until recently only MyISAM tables supported the spatial data type. Over the course of 5 years, we had several database corruptions issues, which could only be fixed by running myismachk on the index file, a process than can take well over 24 hours on a 450 million row table.Ģ). I have subsequently been involved with migrating our spatial data to Postgis and our corporate data (with spatial elements) to SQL Server. I subsequently was involved in MySQL, I attended/spoke at a couple of conferences and was heavily involved in the beta testing of the more GIS-compliant functions in MySQL that was finally released with version 5.5. I decided to try out MySQL and Postgis, at the time there was no spatial in SQL Server and we had a small startup atmosphere, so MySQL seemed a good fit. Ten years ago I was tasked with putting a largish - 450 million spatial objects - dataset from GML to a spatial database. I have worked with all three databases and done migrations between them, so hopefully I can still add something to an old post. I've already done some development using MySql, but I can change if necessary. It appears all 3 of these can talk with R using ODBC, so may not be an issue. I cannot find any noncommercial PostgreSQL equivalent, although I'm not opposed to paying $180 for Devart's dotConnect for PostgreSQL Professional Edition. Thanks to Connector/Net 6.3.4, MySql works well C# and. Despite the 10GB DB limit in SQL Server Express 2008 R2, I'm not sure I want to live with this and other limitations of the free version.

I'm weakest with PostgreSQL, but I am willing to learn if everything else checks out. What database is best for the underlying data store for all this data? Here's my desires: These records include data of at least three different types, and I will be trying to see if each set influences the other. ![]() I need to analyze a few million geocoded records, each of which will have latitude and longitude. Additionally, many third-party tools like phpMyAdmin and DBeaver are available to onboard any newbie quickly.EDIT: I have been using Postgres with PostGIS for a few months now, and I am satisfied. Moreover, it has plenty of documentation, both online and offline, to guide on installation and running a MySQL database. ![]() And, there are already a lot of people, majorly DBAs who have realtime experience in using MySQL. MySQL is one of the world’s most widely used database systems. On the contrary, PostgreSQL has a thriving set of people who voluntarily contribute to its documentation, wiki, and discussion forums. PostgreSQL uses a FOSS (Free and Open-source) license, which is also GPL compatible.Īfter the Oracle took over the MySQL, the developer community lost control which slowed down the new feature addition. ![]() ![]() It means you can use PostgreSQL without paying a penny. It is also an open-source software under the PostgreSQL Global Development Group. He used pure C programming language for development. It was Michael Stonebraker who created PostgreSQL in 1996 at the University of California, Berkeley.
