sql - Is querying directly against tables somehow okay now? -

-

in past, database administrator worth salt have told never query against table directly. in fact, have prevented putting tables in 1 schema & cutting-off direct access schema...thereby forcing query or crud views & procedures etc. , further, protecting data security-layers made sense security perspective.

now enters entity framework...

we use entity framework work. iqueryable king! dbo schema. and, people going directly tables left-and-right because repository patterns , online examples seem encourage practice.

  • does entity framework under hood makes practice okay now?
  • if so, do?
  • why okay now?

help me understand.

  • does entity framework under hood makes practice okay now?

ef doesn't change dynamic. convenience of data access , rapid development, not better way data.

  • if so, do?

it not. does, think, @ least avoid constructing select * type queries.

  • why okay now?

it remains matter of opinion , culture. in general "strict" dba want hit exposed objects layered on top of tables crud. easier tune such queries , maintain control of performance if application using expose custom objects rather using orm or hand-coding direct queries.

imo, orm great rapid protyping , basic stuff, more complex logic or substantial performance should moved custom built objects.

where/when lines vary substantially based on number of things including:

  1. size/load of database
  2. availability of database professionals vs app developers
  3. maturity of company
