I am certain at this point that I will be going in a direction where I will be doing research on a database. My first thought was to explore how to store Tree Data Structures in Postgresql. Which led me to then think about indexes in relational databases and finding an open source relational database that is less mature than Postgresql and improving on the way they store their indexes. Firebird is one that popped up onto my radar. I am unfamiliar with it and still need to do background research. Later, it was pointed out to me that relational databases in general are very mature and don’t have as much room for improvement especially when compared to Time Series Databases. My two ideas are to improve the way indexes are used in Time Series Databases and in Relational Databases. My next steps include looking into what open source databases of these types exists and how they use their indexes.
