IBM Operational Decision Manager is presented as a comprehensive decision automation solution that helps users discover, capture, analyze, automate and govern rules-based business decisions, on premises or on cloud. It is formerly known as the IBM Websphere Operational Decision Management, and before that as the ILOG JRules Business Rules Management System (BRMS).

Presto is an open source SQL query engine designed to run queries on data stored in Hadoop or in traditional databases.
Teradata supported development of Presto followed the acquisition of Hadapt and Revelytix.
IBM Operational Decision Manager can be used to manage complex business processes with less use of IT infrastructure and more use of centralized decision making. Decision-making depends on a logical framework and the creation of commands for better futuristic decisions with less time consumption and more precision and accuracy. IBM's Operational decision manager application is well suited for such scenarios where complex processes have to be streamlined.

Presto is for interactive simple queries, where Hive is for reliable processing. If you have a fact-dim join, presto is great..however for fact-fact joins presto is not the solution.. Presto is a great replacement for proprietary technology like Vertica

Linking, embedding links and adding images is easy enough.
Once you have become familiar with the interface, Presto becomes very quick & easy to use (but, you have to practice & repeat to know what you are doing - it is not as intuitive as one would hope).
Organizing & design is fairly simple with click & drag parameters.

Presto was not designed for large fact fact joins. This is by design as presto does not leverage disk and used memory for processing which in turn makes it fast.. However, this is a tradeoff..in an ideal world, people would like to use one system for all their use cases, and presto should get exhaustive by solving this problem.
Resource allocation is not similar to YARN and presto has a priority queue based query resource allocation..so a query that takes long takes longer...this might be alleviated by giving some more control back to the user to define priority/override.
UDF Support is not available in presto. You will have to write your own functions..while this is good for performance, it comes at a huge overhead of building exclusively for presto and not being interoperable with other systems like Hive, SparkSQL etc.

Presto is good for a templated design appeal. You cannot be too creative via this interface - but, the layout and options make the finalized visual product appealing to customers. The other design products I use are for different purposes and not really comparable to Presto.

It has a positive impact as it provides a great way to define business rules, execute them, update them, manage different versions of rules.
Depending on the complexity of the applications, you can have thousands of rules.
It provides a nice way to test the rules, run simulations with different scenarios, different scales of requests and verify the decisions, performance, etc., and that helps a lot.
Since the decisions can be exposed through REST interface, it makes it very convenient to integrate with different applications, applications using different technologies.
The Business console makes it easy for business users to be able to define, modify rules and not have to depend on IT to do a lot of that work. This helps in bringing the time to change and use the rules to be very short as well as lets IT do more IT related tasks and provide better value to the organization.
