Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"The technical evaluation is very good.""The most valuable features are the counter features and the NoSQL schema. It also has good scalability. You can scale Cassandra to any finite level.""The solution's database capabilities are very good.""The time series data was one of the best features along with auto publishing.""Some of the valued features of this solution are it has good performance and failover."

More Cassandra Pros »

"It's easy to add and remove things in MongoDB. You can alter the tables. MongoDB is faster at reading, slower at writings.""We can define security rules at the database level or the cluster level to grant or deny access to particular users.""The community is great if you have problem.""MongoDB is extremely developer-friendly because when you are starting, there is very little time needed upfront in terms of planning.""I find the integration with other tools very easy.""The most valuable feature is the geometric information done with GeoJSON.""MongoDB has a simple data-loading interface.""The most valuable feature is that you can store unstructured data, which is helpful when you don't know what the best structure should be and you cannot use a relational database because of that."

Cons
"Interface is not user friendly.""Fine-tuning was a bit of a challenge.""The disc space is lacking. You need to free it up as you are working.""The solution doesn't have joins between tables so you need other tools for that.""The solution is not easy to use because it is a big database and you have to learn the interface. This is the case though in most of these solutions."

More Cassandra Cons »

"The transaction could use improvement. From MySQL, for example, you cannot create a transaction if you are reading and writing a document at the same time.""Data encryption is possible using third-party tools but they should have their own encryption capability built-in to this solution.""You need integration with other tools to run the query in MongoDB.""MongoDB should not be used for reporting, analytics, or number-crunching tasks.""Simplifying the aggregation framework would be an improvement.""There should be better integration with other databases.""The performance can be improved.""The on-premises version of the solution is still pretty expensive, especially compared to the cloud version."
