You remember correctly. Athena is the daughter of Zeus, born of no mother, and sprang fully clothed in armour from his head; her domains are warfare, handicraft and wisdom. The syncretic Roman counterpart is Minerva that add justice and law to her domains. There's also a larger symbolic connection to Artemis, Astarte and Ishtar and their cults in the different cultures had many similarities, although there's a clear divide between the Akkadian/Sumerian Godesses whos domains are also sex and fertility while Artemis, Athena and Hestia where perpetual virgins.
She's also the one to who turned Medusa into a Gorgon as some weird kind of punishment against Poseidon for raping Medusa.
