PostgreSQL vs. SAP SQL Anywhere

PostgreSQL is best used for structured data, and best when following relational database design principles. I would not use PostgreSQL for large unstructured data such as video, images, sound files, xml documents, web-pages, especially if these files have their own highly variable, internal structure.

SAP SQL Anywhere is better than not using a database, let's be clear there! However, I wouldn't pick it as my first or even second or third choice. I'd recommend looking at other options. Largely, it appears less powerful both in terms of its robustness and general performance and in its implementation of SQL. The standard Sybase utilities provided are lacking in basic features, and the interactive SQL utility is quite horrendous. However, the great thing is it is an ODBC-compliant SQL-compliant relational database.

• It works well with external data sources and runs on platforms with stable performance.
• Clients can rest assured that their personal information will be safe and secure.
• Many forums discuss setup and usage, and most are free.
• Adding tooling applications to a computer is unlimited.
• PostgreSQL runs on many OS platforms and supports ANSI SQL, stored procedures, and triggers.

• Good performance with relatively large data sets - its cost-based query optimizer is particularly robust
• ANSI SQL compliant
• Supports T-SQL
• Scales well between the desktop (single user) and client/server installations supporting 50-1000 users

• Clearer indications on what is the query plan, to optimize the query
• More out of the box, Postgres specific, SQL functions
• It would be nice to have a more visual aid of the relationship between all tables, but possibly this depend more on the UI used

• I think it should be more user friendly for non-technical users.
• More functional functionalities should be added to the object explore when working with a table to transform data/manipulate data.

Postgresql is the best tool out there for relational data so I have to give it a high rating when it comes to analytics, data availability and consistency, so on and so forth. SQL is also a relatively consistent language so when it comes to building new tables and loading data in from the OLTP database, there are enough tools where we can perform ETL on a scalable basis.

PostgreSQL's availability is top notch. Apart from connection time-out for an idle user, the database is super reliable.

The data queries are relatively quick for a small to medium sized table. With complex joins, and a wide and deep table however, the performance of the query has room for improvement.

There are several companies that you can contract for technical support, like EnterpriseDB or Percona, both first level in expertise and commitment to the software.

But we do not have contracts with them, we have done all the way from googling to forums, and never have a problem that we cannot resolve or pass around. And for dozens of projects and more than 15 years now.

The online training is request based. Had there been recorded videos available online for potential users to benefit from, I could have rated it higher. The online documentation however is very helpful. The online documentation PDF is downloadable and allows users to pace their own learning. With examples and code snippets, the documentation is great starting point.

The online documentation of the PostgreSQL product is elaborate and takes users step by step.

Although the competition between the different databases is increasingly aggressive in the sense that they provide many improvements, new functionalities, compatibility with complementary components or environments, in some cases it requires that it be followed within the same family of applications that performs the company that develops it and that is not all bad, but being able to adapt or configure different programs, applications or other environments developed by third parties apart is what gives PostgreSQL a certain advantage and this diversification in the components that can be joined with it, is the reason why it is a great option to choose.

I worked with Oracle for years during my career. I wouldn't select SQL Anywhere to implement a global ATM system with tens of thousands of concurrent connections, but SQL Anywhere is much easier to use and deploy and works very well in workgroup settings. Query performance often exceeds some Oracle versions without having to rely on database tuning.

The DB is reliable, scalable, easy to use and resolves most DB needs

• Easy to administer so our DevOps team has only ever used minimal time to setup, tune, and maintain.
• Easy to interface with so our Engineering team has only ever used minimal time to query or modify the database. Getting the data is straightforward, what we do with it is the bigger concern.
• It's free. You can't beat that.

Incentivized

• Skilled/experienced resources are less prominent than Microsoft SQL Server or even Oracle, or MySQL, so finding solutions and assistance, if needed, takes more time than it would with other platforms
• You will need to find a good SQL query tool by yourself because the Sybase Central / Interactive SQL utilities are lacking in many basic features, and just generally have a bad user interface
