This is first time I realized it is Mongo and Mango. D'Oh! | :doh:

I think they are trying to replace flat file data with this DB.

MongoDB is not a database it is a document suppository!

What do you get when you cross a joke with a rhetorical question?

It helps to think of it as a file system full of spreadsheets rather than a database...

Despite the DB in it it's name is not a database as we used to know. It is from the family of document-base (http://en.wikipedia.org/wiki/Document-oriented_database[^]). However I found it very useful for log. The fast (and somehow careless) insert, and the ability to filter log records by any of the properties fit me there...

I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

Don't think from a RDBMS perspective. It is meant for a different use. There are few advantages of MondoDB over Traditional RDBMS.

- Really flexible data structures and data types
- Meta data, you can attach any type of information to any records/rows (using traditional db, this is a nightmare, now imagine all those custom fields you need for a CRM application)
- Unmatched Read and Write Performance
- Scalability, you can store really 'big' data
- HDD Storage is cheaper than RDBMS, specially when you need tens of terabytes of storage.
- No need for ORM, you can store your Code side Classes in Database without any extra efforts

So you cannot replace your RDBMS with NoSQL Database, but when you need to store some scientific data, or you want to implement custom caching, or when you want some intermediate space to perform a complex computing, there is no better option. Smile | :)

This is a curious one, I suppose it is horses for courses. We use Couchbase (which I'm lead to understand is similar). We use an in-memory couchbase instance as a cache repository- this works quite well. We also have a disk based instance to store some application information that would normally be held in web.config - this last saves us a re-deploy when version numbers change for example. I dare say NOSql would be good for logging.

Some people rave about NOSql DBs, but I wouldn't want to use one as a main backing store - I saw one company fail as it bought a system that effectively used SQL Sever without referential integrity. [Repair] jobs were lost in the system an the insurer we did the jobs for sacked the company off due to lack of reliability. The company at the time claimed their software handled the integrity and this was more efficient than letting the database do it. A miracle given how many man-years companies like Oracle & MS spend doing the same thing.

I don't get the point

I think the second follows the first: to make an SQL database work properly you have to know what you are doing and this is skilled work. Most companies get devs to do their database work, and this leads to poor database design resulting in rigid structures, poor performance and when really bad a lack of integrity. So the devs fall back on on the idea that I mentioned about the company I worked for that failed - that they'll be easily able to code integrity where needed. My view is this is the point where you should be looking at a relational DB. This link[^] lists relational DB anti-patterns that indicate a NOSql DB might be better, I suspect there is call for the "opposite" set of slides which show signs you'd be better of not using NOSql for certain tasks.

Thanks Keith - this made some question marks vanish.

I will never again mention that Dalek Dave was the poster of the One Millionth Lounge Post, nor that it was complete drivel.

After a decades of adeventure, I am hanging my boots as a consultant. No more yearly contract extesnion pangs or search of the next job.
I have decided to accept the permanent job from my present consulting Jig.Starting Mid of May, I would be their full time emplyoee.

Its kind a reverse thing for most people, but with a kid and a family, I have decided to take a safe bet now.

I hope, this will turn up good.

Yay.. Smile | :)

cheers,
Super

Congrats and Good Luck!! Thumbs Up | :thumbsup:

Unless you take responsibility for the code you write rather than getting paid the contract hours you are a contractor - very different from a consultant. I know, I was a consultant in the 90s and have been a contractor for the last decade, contracting is simple compared to consulting.

And yeah kids cause a completely new risk profile. The wife will feel one hell of a lot more secure for the next couple of years (which can have it's own benefits Big Grin | :-D

) and at least you won't be going through a probationary period - congrats.

Best of Luck!

Since you already work there it should not be too big of a jolt. I hope the compensation is about the same. I once took a full time from consultant (hey, I like permanent) and took quite a hit.

Yes, They were nice enough to match it as close as possible .
Yes Im taking a hit but its under 5% and I am ok with it.

cheers,
Super

Congratulations! I went to work officially as an employee for my best consulting client at one time. They knew me, I knew them, we agreed on terms, etc. ahead of time and it was a good choice. After 12 years, I left on good terms - actually gave them a 1 year notice.

I hope your situation works out as well as mine did. There's something to be said for the security and not having to work double to find clients!

What do you get when you cross a joke with a rhetorical question?

You know those "fish" stickers some people attach to advertise "I'm a christian!" on the back of their car?
(Don't know why they bother - makes no difference to me what religion you are, particularly when you are driving. I just want to know you are competent to drive).

Today I saw one - until we got to the traffic lights: Darwin Fish[^]

If you cut them up they have to forgive you.

Some men are born mediocre, some men achieve mediocrity, and some men have mediocrity thrust upon them.

Actually, they are not afraid of dying, since they then go to heaven. I would stay away from their car.
