How to retrieve, values, names and group names in one SQL query - mysql

Question

I used to have an EAV shema with 4 tables in MySQl 5.7:
articles
article attributes
attribute names
attribute group names
After running into huge complexity, I learned from another question that this is not a good shema. So I got rid of table 2 where all the attributes have been stored and saved them either with values or value_ids directly into table one, as the STI model suggests.
Now I ended up with 3 tables:
articles
attribute names
attribute group names
At first it looked like it made my live easier, but while trying to replace a simple query that was getting all attribute group names and attribute names of a specific article I figured that this is also not ideal.
My previous query looked like this:
SELECT
cag.name_de,
cag.attr_group_id,
attr.attr_de,
attr.attr_id
FROM
articles_attr aa,
cat_attr attr,
cat_attr_groups cag
WHERE
aa.article_id = '181206'
AND aa.attr_id = attr.attr_id
AND cag.attr_group_id = attr.attr_group_id
Now with the new schema, I would need at least this:
Get all group names like e.g. "color"
SELECT
name_de,
attr_group_id
FROM
cat_attr_groups
Get all indirect values which have an ID like e.g. "green"
SELECT
attr.attr_group_id,
attr.attr_de
FROM
articles a,
cat_attr attr
WHERE
a.article_id = '181206'
AND (
(a.dial_c_id = attr.attr_id)
OR (a.dial_n_id = attr.attr_id)
OR (a.bracelet_color_id = attr.attr_id)
)
// pseudo code
$attr[$row->attr_group_id] = $row->attr_de;
Get all direct values:
SELECT
jewels,
vibrations
FROM
articles a
WHERE
a.article_id = '181206'
// pseudo code
$attr[4] = $row->jewels;
Map group names with group ids
foreach($attr AS $key => $value){
// somehow
}
This does not seem to be very elegant. How could I design my shema better or how could those queries be rewritten to retrieve the values in an acceptable query time?
