For Zabbix server and proxy daemons, as well as Zabbix frontend, a database is required. It is not needed to run Zabbix agent.
% cd %%DATADIR%%/%%ZABBIX_BUILD%%/database

PostgreSQL:
shell> psql -U <username>
psql> create database zabbix;
psql> \q
shell> cd database/postgresql
shell> psql -U <username> zabbix < schema.sql
shell> psql -U <username> zabbix < images.sql
shell> psql -U <username> zabbix < data.sql

MySQL:
shell> mysql -u<username> -p<password>
mysql> create database zabbix character set utf8;
mysql> quit;
shell> mysql -u<username> -p<password> zabbix < database/mysql/schema.sql
shell> mysql -u<username> -p<password> zabbix < database/mysql/images.sql
shell> mysql -u<username> -p<password> zabbix < database/mysql/data.sql

SQLite:
shell> cd database/sqlite3
shell> sqlite3 /var/lib/sqlite/zabbix.db < schema.sql
shell> sqlite3 /var/lib/sqlite/zabbix.db < images.sql
shell> sqlite3 /var/lib/sqlite/zabbix.db < data.sql

IBM DB2:
shell> db2 "create database zabbix using codeset utf-8 territory us pagesize 32768"
shell> cd database/ibm_db2
shell> db2batch -d zabbix -f schema.sql
shell> db2batch -d zabbix -f images.sql
shell> db2batch -d zabbix -f data.sql
