Generating performance data and storing in database best practices

Good evening,

I was wondering, what is the best way to store website performance data? Like, booked appointments, daily income, expenses, etc.

So for example I have table booking app.

this is my migration

$table->increments('id');           
            $table->datetime('start');
            $table->datetime('end');
            $table->boolean('assistant_status')->nullable();
            $table->integer('table_id')->unsigned();
            $table->foreign('table_id')->references('id')->on('tables');            
            $table->integer('owner_id')->unsigned();
            $table->foreign('owner_id')->references('id')->on('restaurant');
            $table->integer('booker_id')->unsigned();
            $table->foreign('booker_id')->references('id')->on('users');
            $table->softDeletes();
            $table->timestamps();

So and I want to generate this week report (not past week, but current week daily report Monday, Tuesday, Wednesday, ... etc ) Because people are booking up front!

So I want to store, this data in for example performance table

$table->increments('id');
            $table->integer('owner_id')->unsigned();
            $table->foreign('owner_id')->references('id')->on('restaurant');           
            $table->date('report_date');
            $table->integer('need_assistant'); //stores how many reservations in current week's days needs assistants
//Example Today is Monday and restaurant can see how many users will need assistance on Monday, Tuesday, Thursday... etc.
            $table->integer('do_not_need_assistant'); //stores how many reservations did not needed assistants for their table's
            $table->integer('total_reservations'); //stores total reservations
//Example Today is Monday and restaurant can see how many reservations there are and will be this week - on Monday,  on Tuesday, on Thursday... etc till end of week.
            $table->timestamps();

So question is, how to generate this data?

With past data it is easy, because it will not change.

But how can I generate data for future and if exists update existing data daily?

Thanks!
