I'm looking for a NoSQL database that allows queries that return records that fall in the specified range. I'm not very good with the NoSQL nomenclature (as I'm still only researching whatever they will be viable) so I'll explain it how I would do it in SQL. What I'll need to do, is search for records (let's say forum posts), that are ...

I want to have a schema-free database, with as little maintenance as possible. What do you guys think is the best choice right now, a real no-sql database system like MongoDB, or an API like Friendly, a schema-free library on top of MySQL? I'm not worried right now with scalability nor performance, they're "nice to have". ...
I need to go over a huge amount of text (> 2 Tb, a Wikipedia full dump) and keep two counters for each seen token (each counter is incremented depending on the current event). The only operation that I will need for these counters is increase. On a second phase, I should calculate two floats based on these counters and store them. It sh...
Other folks have asked about using SQL and NoSQL together, and subsequently whether there's a clean way of defining the access objects in a clean, generic way. My question is somewhat related -- which parts of java.sql and javax.sql can be re-used, and is there any plan for Oracle* to get into the NoSQL space and hopefully provide an AP...

I have a few large databases, greater than 100 million records. They consist of the following: A unique key. An integer value, not unique, but used for sorting the query. A VARCHAR(200).

Hey guys, I'm trying to do some tricks with a graph (node/edges) dataset. In this case a set of data where person x follows person y (direct relation). I want to load this data (from a mysql table) into redis (have it running). I've chosen to use Rediska because I use PHP and it seems stable. Rediska has very limited documentation an...
Hi all, I have a long history with relational databases, but I'm new to MongoDB and MapReduce, so I'm almost positive I must be doing something wrong. I'll jump right into the question. Sorry if it's long. I have a database table in MySQL that tracks the number of member profile views for each day. For testing it has 10,000,000 rows. C...
