Why does ERP 2004 installation fill up 30G of SQL data?

Question

Step 2 of mySAP ERP 2004 installation is to create "database instance." I just finished doing that (after running it overnight). Now I see that the installation has taken up 30G of SQLServer database space.
C:\SIDData1 - 10G
C:\SIDData2 - 10G
C:\SIDData3 - 10G
C:\SIDLog   - 2.5G
I am a novice when it comes to SAP installations. This actually is my first successful installation. However, I am just curious on what the heck is being stored in the database that takes up this much space. More importantly, is there anything I can do to reduce the footprint? Are there things I can safely get rid of?
Thank you in advance for your help.

Among the alternatives not mentioned... Using a TiVo DVR, rather than the X1; a Roamio Plus or Pro would solve both the concern over the quality of the DVR, as well as providing the MoCA bridge capability the poster so desperately wanted the X1 DVR to provide. (Although the TiVo's support only MoCA 1.1.) Just get a third-party MoCA adapter for the distant location. Why the hang-up on having a device provided by Comcast? This seems especially ironic given the opinions expressed regarding payments over time to Comcast. If a MoCA 2.0 bridge was the requirement, they don't exist outside providers. So couldn't the poster have simply requested a replacement XB3 from the local office and configured it down to only providing MoCA bridging -- and perhaps as a wireless access point? Comcast would bill him the monthly rate for the extra device, but such is the state of MoCA 2.0. Much of the OP sounds like frustration over devices providing capabilities the poster *thinks* they should have.
