What is the format of a flat file?
A flat file can be a plain text file (e.g. csv, txt or tsv), or a binary file. Relationships can be inferred from the data in the database, but the database format itself does not make those relationships explicit. The term has generally implied a small database, but very large databases can also be flat.
Is CSV better than XML?
CSV is useful when you just have a series of a values that relate to some piece of information and you know you will always store values for each field. XML has the benefit of having self-describing data (tags) and having hierarchy – which gives you a lot more flexibility in the way that you store the data.

Is CSV a flat file?
There are two common types of flat files: CSV (comma separated values) and delimited files. Both are file formats that represent relational data in a text file.
Why do we use flat file?
Data warehousing projects use flat files to import data. There is no data manipulation performed on the stored data, but they are the preferred option because of how easily they carry information from the server. Flat files are a bare means of storing table data but do not hold relations between the tables within them.
Is SQL a flat file?
Using a structured query language (SQL) instead of a collection of files in a file system, users or applications won’t need to understand the location and data layout. One of the most common flat files is a comma-separated value (CSV) file.
Which is better JSON or CSV?
CSV format is referred to as the most compact format from all the formats of a file. CSV format is about half the size of the JSON and another format file….JSON vs CSV Comparison Table.
| Basic Comparison | JSON | CSV |
|---|---|---|
| Versatile | JSON is much versatile. | CSV is very less versatile. |
Is XML heavy?
The primary appeal of XML is that it was ideal for transferring data between other formats. It required far fewer filters for data conversion to share data between different applications that might have their own proprietary format. Because it’s so “heavy,” XML is considered to be slow when working at Web speeds.
Which is better XML or JSON?
JSON is faster because it is designed specifically for data interchange. JSON encoding is terse, which requires less bytes for transit. JSON parsers are less complex, which requires less processing time and memory overhead. XML is slower, because it is designed for a lot more than just data interchange.
Is XML same with txt file?
XML file is organized and neat document while txt file is fairly organized file, somewhat TXT file neat because some statement in the plain text file and its content are organized with some commands like XML an organized textual file.
Is Notepad a flat file?

What is the difference between comma delimited file and XML?
Both a comma delimited file and a XML file are “human readable.” But in general, the comma delimited file is much easier on my eyes than a XML file; the tags typically take up as much if not more space than the data.
Is the cost of parsing XML less than developing a new extract?
The initial feeling was that the infrastructure cost of parsing XML was less than the cost of developing a new extract job. To make a long story short, the ETL batch processing maxed out all the server’s CPUs and remained as such till the job completion.
