Hello all. I am trying to create a database that contains the street name or POI name and their corresponding lon lat. I plan to get the data from the .osm that I have downloaded. Are there already tools available to do this?

Sorry but I am really new to this. All I know is that the tools above can extract and manipulate data. But I can't seem to find out how to transfer selected data to a database. My goal database is like this

LocationName Longitude Latitude

Sorry for troubling you but it will be nice if you can help me. thank you!

Read the documentation about the mentionned tools (search on the OSM wiki). You will see that they also transfer data to databases. Also check nominatim doc for geo- and reverse-geocoding.

I would not encourage you to do this. There are no tools in mapping systems that extract names/text “with their corresponding lon lat”. Simply, this is meaningless. As a rule, names are attached/related to objects and not to positions. Where and how a name will be displayed/rendered (along a line-work object, inside an area object, close to a point object..) is just a matter of a designer’s decision. In a modern vector transmission based mapping system if the names are rendered this is done on-the-fly, dynamically positioned, scaled, curved… depending on the configuration of the portion of any particular object that falls into the view-port to display. Shortly, there is no direct and 1:1 relation between names and positions. Yet, if you insist on your data-base and you see certain use for it, with a small programming effort you could create a name-position (1:N) record array and from there your data-base
