I get frustrated with the layers between relational data and data structures you pass around in code. So for example, if you want a build a simple REST api for your data model, you have glue code to read/write the data and transfer it to/from DAO's (Data access objects). Then you have glue code to transfer the data into to/from object model you expose via the API. This feels like 90% of server side CRUD app programming these days. It's not quite boilerplate because it's a mix of ORM optimizations for your data model and data massaging to make it more digestable to end users of your API.
