Aside from the spreadsheet function, the Lotus application also supports the creation of graphs and charts including basic operation for databases. These three main functionalities are used by Lotus as the basis for the creation of the 123 file extension. Having the abilities to support these three functions, the application eventually incorporated the support for its integration into other office and productivity applications developed by other software houses. This allowed for a broader usage of the 123 file extension to an extent that it even reached the stature of becoming one of the more dominant applications during the DOS era.
