No one can fault the OP for suggesting that we look to use technology to our advantage, making something we need to do more efficient. However, this is one of those things that has so many real obstacles that it is prohibitive. Here are some obvious problems:
1. Who will verify the information contained in this shidduch resume? If it is not verified, we continue to have the problem, well known to the community that the word ???? is ???? ????? for ??? ???? ??? ????. Nothing gained.
2. Information that gets entered on a database is concrete. There is no way one can successfully include the needed information about personality, emotional presentation, or about chemistry. One would still need to invest the time in collecting information about impressions from others. No one would be so insane as to trust this public database to make or break a shidduch.
3. It is frightening that this database could someday be used as a mechanism to have shidduchim developed online, with a formula to determine compatibility based on concrete data.
4. In the real shidduch world, there is a give and take process where someone will determine that factors that would otherwise be considered a negative are accepted because of the desire for the positives. No database can substitute for human judgment.
5. This will contribute to the end of the world. The gemora tells us that HKB”H is busy ???? ?????? ??????. There would be no work left for Him!
6. This database would also apportion which shadchanim should accept which shidduchim. That almost guarantees that the shadchan that will deal with my child will be a total stranger who does not know me, my family, my child, and the same for the other side. That should be scary.
There are more issues. Certain things cannot be replaced by robots. It might work well on the assembly line in a factory. For truly human matters, it just makes for a good joke.
