AI Thread Summary
The discussion clarifies the term "database schema," emphasizing its role as a blueprint for organizing database elements. It includes details about tables, fields, data types, constraints, references, indexes, and security access. Participants agree that a loose definition could be "a schematic of the database." Visual representations, such as those found in Google Images, can help illustrate these concepts. The conversation concludes with an acknowledgment of the initial confusion and a newfound understanding of the topic.

What I guess (based on experience) is it's asking about this.

Table student-:
Name
Roll
Grades

Table Teacher-:
Salary
Experience
Subjects Taught

This is database schema according to my guess. Is this the context used here?
A rather loose definition could be a "schematic of database". Would it be appropriate here?

yes and yes. If you do a google search of "database schema" and clik on images. This will become very clear.
Database schemas will contain:
-list of tables, and what fields they contain
-list of fields, and what kind of data they contain. (numeric, text, etc..)
-constraints on the data (uniqueness, range, list of values to select from)
-fields that are a reference to a record of another table.
-indexes to make looking up data easier.
-security access and user information
-often a way to add code to a database (user defined functions, stored procedures).

and you should be able to find that in an elasticsearch index in some form

thanks for the quick heads up. i actually got it after asking the question, i was stuck in it like 6 hrs(new level of dumbness achieved lol), then i read the next few lines, it became evident.

Thread 'Have I solved this structural engineering equation correctly?'
Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
