That's one way Tyreman, and it will absolutely get the job done.
However, in woodworking there are always alternatives! Here are a few worth considering,
The dovetail in the rail that sits above the drawer shouldn't, IMO, be full depth because it risks exposing the edge of the mortice which looks really tacky. Likewise on those double tenons that joint the lower drawer rail into the legs, leave a shoulder so there's no risk that the mortice is visible.
One little thing worth pointing out, I normally secure the top above the drawer with screws straight through the rail. Make sure you drill those holes
before assembly (as you can see in the above photo), because if you drill
after assembly you won't have access to countersink them.
I secure the top on the other three sides with buttons. In the video the buttons are fairly crude and basic. Nothing wrong with that because they're invisible inside the drawer. But if there's no drawer, then on really high class work you might want to make the buttons a little tidier as the client will see them if the table is ever moved and flipped upside down. I use shaped buttons like these,
if you gang cut them they don't take much longer to make than basic buttons, but they add that fractional bit of extra quality to a project.
The drawer in the video is the simplest form of dovetailed drawer. That's okay, it does the job. However, in order to accommodate the groove the drawer sides have to be that bit thicker, say around 12mm. There's something a little more elegant about a drawer with
thinner drawer sides, say around 8mm or even less on a smaller drawer. But with thinner drawer sides there's no room for an adequate groove, so you have to add drawer slips. Unfortunately that one tiny change adds a lot of complexity to drawer making, so it's probably something left for a later effort, but in first class work drawer slips are pretty much mandatory.
This what the underside of a drawer with slips looks like,
But to do the job properly the groove in the slips is then offset from the groove in the drawer front,
Which then requires the drawer bottom to have matching offset tongues,
Like I said, this does start to get a bit complex, but once you've done a few it becomes second nature. One big advantage of this form of drawer construction, besides thinner and more elegant drawer sides, is that for wider drawers you can easily incorporate muntins, the central divider that supports the bottom on wider drawers,
