;Task:
Create a table to store addresses.
You may assume that all the addresses to be stored will be located in the USA. As such, you will need (in addition to a field holding a unique identifier) a field holding the street address, a field holding the city, a field holding the state code, and a field holding the zipcode. Choose appropriate types for each field.
For non-database languages, show how you would open a connection to a database (your choice of which) and create an address table in it. You should follow the existing models here for how you would structure the table.

J is a programming language, not a database, but it ships with a database built in the programming language called [[j:JDB|JDB]]. Using that, assuming <tt>hd</tt> is your database, then:
<
addrID autoid;
addrStreet varchar
Line 400 ⟶ 539:
addrState char
addrZip char
)</
Of course J can connect external databases too, using e.g. [[j:Studio/ODBC%20Basics|ODBC]]. See the [[j:DB|list of J database topics]].
=={{header|Java}}==
Java can connect with many databases.
This example completes the task with a random access file, instead of using an external library.

===version 1===
A REXX program can call SQL or any other database system, but the version shown here is a RYO (roll your own).
Practically no error checking (for invalid fields, etc.) has been coded.
The fields are for the most part, USA specific, but could be expanded for other countries.
In addition to "state", fields such as province, municipality, ward, parish, country, etc) could be added without exclusion.
Also, a history logging facility is included which tracks who (by userID) did what update (or change), along with a timestamp.

While Stata is not a database language ''per se'', it is not uncommon to store address data in a Stata dataset. The following creates an empty dataset.
Other possibilities include using the '''[https://www.stata.com/help.cgi?odbc odbc]''' command or a C or Java plugin to connect to a database. See the FAQ for more details: '''[https://www.stata.com/support/faqs/data-management/using-plugin-to-connect-to-database/ How do I connect to a database by using a Stata plugin?]'''.
