How to extend tt_address - typo3

Question

I created my first extbase extension which works fine. Now i want to enter address informations into my extension, like city, zip code and street.
I preffer to create a relation to "tt_address". My aim is to create a 1:N relation from "tt_address" to my extension.
But the extension "tt_address" is based on "pi_base", how can i handle this issue? How must my "tca" look?
How can i create a record form my "createAction" into the "tt_address" table, should i need the object manager?
Is there a example on web?
Update, i extend my model with street, zip and city:
/**
* street
*
* #var string
*/
protected $street;
/**
* street
*
* #var string
*/
protected $zip;
/**
* street
*
* #var string
*/
protected $city;
public function setStreet($street)
{
$this->street = $street;
}
public function getStreet()
{
return $this->street;
}
public function setCity($city)
{
$this->city = $city;
}
public function getCity()
{
return $this->city;
}
public function setZip($zip)
{
$this->zip = $zip;
}
public function getZip()
{
return $this->zip;
}
After this i extend my typoscript setup.txt
plugin.tx_oaevents {
view {
templateRootPath = {$plugin.tx_oaevents.view.templateRootPath}
partialRootPath = {$plugin.tx_oaevents.view.partialRootPath}
layoutRootPath = {$plugin.tx_oaevents.view.layoutRootPath}
}
persistence {
storagePid = {$plugin.tx_oaevents.persistence.storagePid},148
classes {
Mab\Oavents\Domain\Model\Events {
mapping {
tablename = tx_nnaddress_domain_model_address
columns {
zip.mapOnProperty = zip
street.mapOnProperty = street
city.mapOnProperty = city
}
}
}
}
}
And in last step i extend my extension TCA.
address' => array(
'exclude' => 1,
'label' => 'Events',
'config' => array(
'type' => 'select',
'foreign_table' => 'tt_address',
'minitems' => 0,
'maxitems' => 1,
),
),

You need to create a model and map it in TS to table tt_address. In this mapping you need to set each field from your model to a column in table that you want to map. When you will have model and mapping everything else is the same. You create controller and repository for your model and you can create createAction that will insert something to table tt_address
