Translating ERD diagrams into SQL DDL statements - Database Administrators Stack Exchange


i establishing database students , courses using erd. style of erd using similar diagram below erd diagram question:

enter image description here

note: picture above not erd, style of erd using.

a simple create statment used attributes of each entity, other ddl statements enforce relationships, weak entities, , multi-way relationships?

the way can enforce relationships between tables creating foreign key referencing primary key other table. both keys defined either creating or modifying table using create statement or alter statement, respectively.

sqlite - Unique combination of values - Database Administrators Stack Exchange

i want create database program. use sqlite, although others option. i have columns a , b , c , d . a unique , primary key. b , c , d allowed contain duplicate value. however, don't want combinations of b , c , d repeat. instance, sample valid db: a b c d 0 18 n kiwi 1 12 v kiwi 2 15 t orange 3 12 j kiwi 4 12 t banana 5 31 f apple 6 10 h kiwi 7 15 y orange 8 20 b apple 9 1 m grapefruit 10 7 s apple 11 4 h banana 12 31 t egg sample invalid db (rows 2 , 7 ): a b c d 0 18 n kiwi 1 12 v kiwi 2 15 y orange 3 12 j kiwi 4 12 t banana 5 31 f apple 6 10 h kiwi 7 15 y orange 8 20 b apple 9 1 m grapefruit 10 7 s apple 11 4 h banana 12 31 t egg is there standard database rule or concept applies this? i can of course validation in code, manually querying db. believe construct fifth bcd column, concatenates other three, , required un...

linear algebra - Matrix Columns VS Rows - Mathematics Stack Exchange

i confused on geometric meaning of columns , rows in matrix. understanding 3blue1brown's linear algebra series elements of matrix column coordinates tip of single basis vector lands on @ end of linear transformation, while elements of matrix row coefficients of equation (if matrix augmented) or expression (if matrix not augmented). however, studying matrix subspaces, , appears both columns , rows can treated vector tip coordinates solve different subspaces. is there second vector geometric interpretation of matrix elements of row coordinates on tip of single basis vector lands (which presumably identical applying original geometric interpretation matrix's transpose)? if so, geometric or conceptual difference between matrix columns , rows, justifies differences in how operate on them, , how relate them linear systems of equations? actually, 3blue1brown gives interpretation well, though doesn't go deep enough particular aspect. in chapter 7, discusses dualit...
