matlab - Indexing over all values in nested struct -

-

i have nested struct contains values , defined as:

mystruct.level1.a = 1; mystruct.level1.b = 2; mystruct.level2.a = 8; mystruct.level2.b = 9;

i want perform operations on elements in level1 , level2. want access values in level1 , level2, put them in vector, without referencing nested field names.

e.g. i'd like:

level1_vector = [mystruct.level1]

which output:

level1_vector = [1 2]

how can that?

use combination of 2 functions below:

cell2mat(struct2cell(mystruct.level1))

What is the difference between data design and data model(ERD) -

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
