Seeking Schema for vCard Data Elements - database-schema

I need a relational database schema to store vCard ver 3 data elements.
Rather than reading the RFC and designing one from scratch, I'm looking to see if someone who has already done this is willing to share their database design.


(http://i.stack.imgur.com/61qGU.png)
This is my DB schema for a VCard 3.0. This works quite well with CardMe library, each type is mapped to a database table and the many-to-many / one-to-many relationships are enforced through foreign keys.

MySQL Workbench - Cant select FK column. Dropdown not populating

Here are my tables CREATE Statements:
CREATE TABLE `User` (
`UserId` int NOT NULL AUTO_INCREMENT,
`CompanyId` int NOT NULL,
`FirstName` varchar(50) NOT NULL,
`LastName` varchar(50) NOT NULL,
`UserName` varchar(100) NOT NULL,
PRIMARY KEY (`UserId`),
KEY `FK_Company_User_idx` (`CompanyId`),
CONSTRAINT `FK_Company_User` FOREIGN KEY (`CompanyId`) REFERENCES `Company` (`CompanyId`)
) ENGINE=InnoDB AUTO_INCREMENT=256 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
CREATE TABLE `Notification` (
`NotificationId` int NOT NULL AUTO_INCREMENT,
`Email` varchar(100) DEFAULT NULL,
`Message` text,
`Subject` varchar(100) DEFAULT NULL,
`UserId` int NOT NULL,
PRIMARY KEY (`NotificationId`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
I am trying to create a FK between UserId in Notification and UserId in User but the dropdown for selecting the field is not populating.
Any help is appreciated.

PostgreSQL gives syntax error at "foreign" or near

These are tables before referances
CREATE TABLE olap.time (
idtime SERIAL NOT NULL PRIMARY KEY,
year integer,
month integer,
week integer,
day integer
);
CREATE TABLE olap.addressees (
idaddressee integer PRIMARY KEY NOT NULL,
name varchar(40) NOT NULL,
zip char(6) NOT NULL,
address varchar(60) NOT NULL
);
CREATE TABLE olap.customers (
idcustomer varchar(10) SERIAL PRIMARY KEY autoincrement,
name varchar(40) NOT NULL,
city varchar(40) NOT NULL,
zip char(6) NOT NULL,
address varchar(40) NOT NULL,
email varchar(40),
phone varchar(16) NOT NULL,
regon char(9)
);
After creating this tables I want to create this table
CREATE TABLE olap.fact(
idtime integer NOT NULL,
idaddressee integer NOT NULL,
idcustomer varchar(10) NOT NULL,
idfact integer NOT NULL,
price numeric(7,2),
PRIMARY KEY (idtime, idaddressee, idcustomer),
FOREIGN KEY (idaddressee) REFERENCES olap.addressees(idaddressee),
FOREIGN KEY (idcustomer REFERENCES olap.customers(idcustomer),
FOREIGN KEY (idtime) REFERENCES time(idtime)
));
But I get error as
"ERROR: syntax error at or near "REFERENCES"
LINE 9: FOREIGN KEY (idcustomer REFERENCES olap.customers(idcustom..."
Thanks in advance

The idcustomer from olap.fact and idcustomer from olap.customers has different datatype SERIAL and Varchar(10),
I have corrected the datatypes and validated the code below
CREATE TABLE olap.time (
idtime SERIAL NOT NULL PRIMARY KEY,
year integer,
month integer,
week integer,
day integer
);
CREATE TABLE olap.addressees (
idaddressee integer PRIMARY KEY NOT NULL,

);
CREATE TABLE olap.customers (
idcustomer varchar(10) PRIMARY KEY ,
name varchar(40) NOT NULL,
city varchar(40) NOT NULL,
zip char(6) NOT NULL,
address varchar(40) NOT NULL,
email varchar(40),
phone varchar(16) NOT NULL,
regon char(9)
);
CREATE TABLE olap.fact(
idtime integer NOT NULL,
idaddressee integer NOT NULL,
idcustomer varchar(10) NOT NULL,
idfact integer NOT NULL,
price numeric(7,2),
PRIMARY KEY (idtime, idaddressee, idcustomer),
FOREIGN KEY (idaddressee) REFERENCES olap.addressees(idaddressee),
FOREIGN KEY (idcustomer) REFERENCES olap.customers(idcustomer),
FOREIGN KEY (idtime) REFERENCES olap.time(idtime)
);

CREATE Statement in PostgreSQL error relation does not exist

My question is similar to the one posted earlier in the Community. questions/62936399/error-sql-state-42703-while-trying-to-insert-data-into-my-table
In PostgreSQL, I'm trying to run CREATE Table Statement so that I can continue with inserting values. Although my CREATE statement fails so I can't get on with INSERT statement. The error message that keeps coming up ERROR: relation "eventrequest" does not exist

I have re-did the entire CREATE Statement twice although the error message does not change.

Find cause of error "constraint xxxx is not a foreign key constraint" in Postgresql

I have defined these tables:
CREATE TABLE "public".category (id BIGSERIAL NOT NULL, name varchar(255) NOT NULL, PRIMARY KEY (id));
CREATE UNIQUE INDEX category_name ON "public".category (name);
CREATE TABLE "public".clusters (id BIGSERIAL NOT NULL, name varchar(255) NOT NULL, PRIMARY KEY (id));
CREATE INDEX clusters_name ON "public".clusters (name);
CREATE TABLE "public".keywords (id BIGSERIAL NOT NULL, text varchar(255) NOT NULL, category_id int8 NOT NULL, top_results int4, cluster_id int8, month_requests int4, click_cost float8, PRIMARY KEY (id));
CREATE INDEX keywords_text ON "public".keywords (text);
ALTER TABLE "public".keywords ADD CONSTRAINT FKkeywords488682 FOREIGN KEY (cluster_id) REFERENCES "public".clusters (id);
ALTER TABLE "public".keywords ADD CONSTRAINT FKkeywords446526 FOREIGN KEY (category_id) REFERENCES "public".category (id) ON UPDATE CASCADE ON DELETE CASCADE;
added one record to category table:
INSERT INTO "public".category(id, name) VALUES (1, 'Test');
And now when I try to add record to keyword table
insert into "public"."keywords" ( "category_id", "text") values ( 1, 'testkey')
I got error:
ERROR: constraint 16959 is not a foreign key constraint
When I do
select * FROM pg_constraint;
I can't see constraint with this id. I can't understand what is the cause of this problem.

postgres SQL issue with decimal

Hello I have an issue with line 8 something to do with decimal.
any suggestions?
CREATE TABLE car (
cid CHAR(8) PRIMARY KEY,
reg_no VARCHAR(9) NOT NULL,
colour VARCHAR(15) NOT NULL,
maker VARCHAR(20) NOT NULL,
model VARCHAR(20) NOT NULL,
fuel_type CHAR(6) CHECK((fuel_type IN ('petrol', 'diesel'),
eng_size DECIMAL(2,1) NOT NULL,
owner CHAR(6) NOT NULL,
FOREIGN KEY (owner) REFERENCES client (client_no)
ON DELETE CASCADE
ON UPDATE CASCADE,
);

your '))' were missing at the end of 8th line, and you had an extra ',' at the end before ).
This is fixed version
CREATE TABLE car (
cid CHAR(8) PRIMARY KEY,
reg_no VARCHAR(9) NOT NULL,
colour VARCHAR(15) NOT NULL,
maker VARCHAR(20) NOT NULL,
model VARCHAR(20) NOT NULL,
fuel_type CHAR(6) CHECK((fuel_type IN ('petrol', 'diesel'))),
eng_size DECIMAL(20,15) NOT NULL,
owner CHAR(6) NOT NULL,
FOREIGN KEY (owner) REFERENCES client (client_no)
ON DELETE CASCADE
ON UPDATE CASCADE
);

The line before eng_size field declaration missing closing parenthesis )
Change it from
fuel_type CHAR(6) CHECK((fuel_type IN ('petrol', 'diesel'),
To
fuel_type CHAR(6) CHECK(fuel_type IN ('petrol', 'diesel')),
Also, remove the , from the last line
FOREIGN KEY (owner) REFERENCES client (client_no)
ON DELETE CASCADE ON UPDATE CASCADE
