I've always considered LLC's to be for small personal businesses such as software consultancies, design agencies and so on. But there are large companies I'd have thought would be full corporations but are not. For example, Kaiser Permanente is an LLC with 150,000 employees. Chrysler, the car company, is also an LLC.What benefit do they get from being LLCs?
There are many factors to consider when thinking about whether you choose a relational database (RDBMS) or NoSQL database. There are the obvious: Cost tradeoffs (NoSQL DBs are usually open source and free, e.g. MongoDB, Cassandra, etc) whereas RDBMSes are often pricey (Microsoft SQL Server, Oracle). Performance: NoSQL DBs are often much faster than relational DBs but they are also build targeting a single use-case. Using them outside this use-case can be extra challenging but not impossible. There are also less obvious tradeoffs such as does the team have experience (or desire to gain experience) with a given NoSQL DB? Here is a great overview video from Martin Fowler: https://www.youtube.com/watch?v=qI_g07C_Q5I And another intro talk (first half) I recently did at a conference in London: https://www.youtube.com/watch?v=_r7ozqiTN2k
