Mongo has had a few problems that have surfaced recently that really justify the name.
NoSQL isn't bad, it's just good for some circumstances, SQL is good for other, and graph DBs good for others. I work in fintech, as does @Zak, and SQL is pretty common in that industry
This is some serious spaghetti code. Once you get this working, I would strongly recommend to post the working code at codereview.stackexchange.com. There is a lot of things you need to learn. — Lundin14 secs ago
Try this to get a good job: 1. Attend a conference related the languages / technologies you like, and where many related companies host their booths. Go wearing your Code Review T-shirt 2. Talk to the interesting companies, most importantly the developers. Find out what it's like to work there. If sounds good, find out if they are hiring, and how to take their test 3. Prepare well for the tests, for example by solving problems and writing clean code as much as possible
Code review: every line of the input file is checked to see if $. == 1. It is faster and more concise and readable to just my @arr1 = split /\t/, <FH> before the loop — Borodin38 secs ago
It's so good when you have to push out a fix and you can follow a check list to make sure everything is done right (better yet would be automating but eh)
input : 1000 23 100 26 32
output : 23 26 32 100 1000
since 23 has '2' factors and 26 has '4' factors and 32 has '6' factors.. and so on....

Also, @JeroenVannevel your analyser looks seriously amazing from the usage gif, but I just can't understand the code - there's a lot you'd need to know before reading it, if that makes sense. Any resources I could look at? Something simpler perhaps?

As title says, this piece of code migrates files (binary and metadata) from a database to another one with different structure.

You don't have any performance metrics, so there is no telling whether this will have a significant effect, but one of the things you could do is combine your queries.

Welcome to Code Review! Unfortunately, this is not a review of the given code. Note that this question is likely to be closed soon and actually shouldn't be answered. Welcome anyway, feel free to join us in The 2nd Monitor if you got any questions. — Mast8 secs ago
I'd need more context so please consider some suggestions as implicit questions.
In PipeLineStep class StepName property is a read-only property. If you just return a constant value you may want to make it a constructor parameter instead (where you may also include some sort of validation):

It realllly annoys me on SO how answerers just give the user the answer instead of trying to explain what is wrong. Even worse when they say "Just try this" and have a code dump...
int main(void) {
int n,a[2][25],i,j;
printf("Enter the no. of items\n");
scanf("%d",&n);
printf("Enter the items\n");
for(j=0; j<n; j++)
{
scanf("%d",&a[0][j]);
}
for(j=0; j<n; j++)
{
a[1][j] = facts(a[i][j]); // here i is undefined
}
I don't think this is grounds for closing. It's a good code review answer to point out the OP that he should initialize variables, and also keep an eye on compiler warnings, because any decent compiler will warn for this
To be honoust, I pointed the coder to a link of factorization algorithms, and he promptly asked me how to improve his factorization algorithm. I also want all the answers on a plate
coder is probably like all the other c#, js, c++, c, cobol, fortran, sql, mysql, mongo, perl, lisp, python, matlab, .... coders. Doesn't bother doing any research, and refuses to participate in any code reviews, or use branching. What can I say. I'm off to lunch at Pret. Yes. to play on my broken 2 core 1.4MHz 8 year old laptop.
not everyone has drive to do research, they just want to get the job done. most people in 2nd will use those languages but do care about researching it, reviewing and branching etc.

Before I assign anything to num, is the value of num indeterminate?
