Nosql Nosql Vs Relational Databases Nosql database systems are often highly optimized for retrieval and appending operations and often offer little functionality beyond record storage (e.g. key value stores). the reduced run time flexibility compared to full sql systems is compensated by marked gains in scalability and performance for certain data models. @user2154283 i was thinking of using a fault tolerant database to reduce the risk of loosing my data. also we are planning to perform some sort of encryption on the images so they are accessible only through our application. i thought these both can be achieved by storing images in a nosql database. –.
Nosql Nosql Vs Relational Databases Secondly, nosql allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle. Nosql databases approach modelling from a different point of view generally. nosql modelling usually begins with asking questions on how the data in the database is going to be queried, so the main modelling is 'what are the list of questions that i want to ask of my database', whereas with sql databases, modelling usually is a function of what. And i came to the following conclusion: if nosql databases are generally schemaless, you don't actually have a 'schema' to illustrate in a diagram. thus, i think you should take a "by example" approach. you could draw some mindmaps exemplifying how your data would look like when stored in a nosql db such as mongodb. "nosql" is a buzzword describing a diverse collection of database systems that focus on "semi structured" data (that do not fit well into a tabular representation), sharding, and high concurrency at the expense of transactional integrity and consistency, the latter being among the basic tenets of relational database management systems (rdbms).

Data scaling sql works best when all the data fits on one server (up to a few tb). the reason a lot of nosql stores don't have join is that they were designed not to require all the objects to be on one server. performance scaling nosql stores do tend to be faster at handling high traffic, but not necessarily by enough to matter. I'm investigating the different types of nosql database types and i'm trying to wrap my head around the data model of column family stores, such as bigtable, hbase and cassandra. first model. some people describe a column family as a collection of rows, where each row contains columns , . an example of this model (column families are uppercased):.
