(Information Science Master) Lecture on Databases
- The idea that applications and databases should be separated through an interface.
- Data should be usable persistently, even as applications change over time.
- A highly important concept.
- Nowadays, it feels obvious.
- In the past, applications and databases were not separated.
- As a result, if an application became unusable, the data in the database would also become inaccessible.
- This was problematic, so efforts were made to separate the data model, among other things.
