An <u>attribute</u> is the equivalent of a field in a file system.
In a computer, a file system or a filesystem refers to a system where you name the files and keep them logically in order to use or retrieve them later. Without this system, whatever information you store, it would not be isolated into individual files and it would then become difficult to identify and retrieve them.
A file management system in database management system, serves a similar purpose. It allows you to access single files or tables at a time. Here, the data is stored directly in files, which makes it easily accessible.

Porosity is a cavity-like discontinuity and occurs due to the entrapment of gases in the molten weld pool. These entrapped gases don't get a chance to escape from the molten weld pool and hence cause porosity.
<h3>Which discontinuities are caused during welding?</h3>
Weld discontinuities can be defined as "an interruption of the typical structure of a weld, such as a lack of homogeneity in the mechanical, metallurgical or physical characteristics of the weld." Porosity is considered to be the most critical discontinuity. Weld discontinuities include porosity, incomplete fusion, excessive melt.
