Is it faster to read from file or database?

Is it faster to read from file or database?

In general the speed at which you can open a file for reading will be better than the speed at which you can establish a network connection. So for very simple operations, the filesystem is definitely faster. Filesystems will probably beat an RDBMS for raw read throughput too since there is less overhead.

Why are databases better than text files?

A text file can work just fine for simple projects, but a database has many more features that can help you organize, backup, and query your data much more efficiently and robustly.

Is writing to a file faster than writing to a database?

Writes would, in general, be faster too, as the DB engine doesn’t have to wait for the file IO to complete before returning since they can take a “lazy write” approach. A poorly tuned database, on the other hand, will be orders of magnitude slower than any file based IO. DB tuning matters.

Is CSV faster than database?

If you always need all data from a single table (like for application settings ), CSV is faster, otherwise not.

Why is database faster?

Most people ask why is database so faster when compared to flat file entries of data. There are many reasons behind that, one of them is indexing. Of course the speed of the underlying disk subsystem’s also plays a major role in increasing database speed.

Why use a database over a CSV?

They’re faster; unless you’re loading the entire flat file into memory, a database will allow faster access in almost all cases. They’re safer; databases are easier to safely backup; they have mechanisms to check for file corruption, which flat files do not.

Can we use txt file as database?

Yes you can use a . txt file as a database but you should make it a lot easier on yourself in the long run and learn mySQL in a couple of hours so you are doing it more along the lines of industry standards.

Is append faster than write?

Writing to a file in place is fine and only takes microseconds for the open, write, and close. But if you append a file, closing the associated file handle is going to take a few milliseconds.

What makes SQL fast?

1. Use column names instead of SELECT * While using SELECT statements use only the columns you need in your result, instead of using SELECT * from … This will reduce the result size considerably and speed your SQL query.
