SQL Anywhere® solutions aim to deliver enterprise-level data management and
synchronization capabilities. The solutions are designed to run in remote and
mobile environments on a wide range of small-footprint devices and in
real-world conditions.
Exasol is well suited for data warehousing, BI, ML, AI - all analytical queries. It has almost no operation cost, because it is selfmaintening the indexes etc.
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.
We have found Exasol to be very fast at summarizing large data sets. It has been a great backend for both reporting tools and data analytics/business intelligence. Combined with the fact that data import is also very fast it makes it ideal for a real-time ELT architecture.
Exasol is low maintenance. No indexes to maintain (The database auto-manages them) and very little tuning is required.
Query processing is optimized for high throughput and high parallelization. This means that even under high loads performance degrades gracefully as opposed to having "pile-ups" and "meltdowns". This has made it a very reliable database for us.
It queries large set of data and has a speedy run time.
With the rate at which data is going with Internet of All things, SQL Anywhere cuts across database applications outside of traditional data centers in which department data's are stored.
The amazing thing about SQL Anywhere is the relational standard it maintains as a structured language that works across any DB. Yes, you might need to adopt some changes within the environment DB you are working; however, its important to know SQL itself to help archive data goals.
I have had only positive experiences with their support. They are fast, knowledgeable, and courteous. Online support requests get picked up within hours. I've only once had to use their hotline and that was for an emergency. There was even one minor non-security bug report that I reported and which they fixed in the following week's minor release. I was quite impressed.
We looked at some others too, but was 5 yrs ago so I don't recall the list. Exasol had the best performance per cost, outstanding performance, and was easy to evaluate. Even their community addition running on my laptop was faster than our existing reporting solution.
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.
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
