Big changes finally make their way into angular v16

TL;DR: ngcc is going to be dropped and zone.js is finally a thing of the past due to signals/reactivity.


What do I need to do?:
- if your app still uses the viewengine directly (as it was sometimes done in <v8) you'll have to get rid of that
- if your app uses angular as a framework and not just a templating engine and you use the native history api you'll have to switch to angular Location instances. (boo 👎🏻)
- keep in mind that (the sometimes extensive and necessary) performance optimizations should become a thing of the past - if you're close to upgrading think twice before you invest time in complex optimizations


See here and here.

In short: angular finally takes a step to becoming a sensible and modern web framework again. Lets see if the can achieve the same levels of DX/Security/Speed that other frameworks provide 😋

Visualizing a SQL query.

SQL statements are executed by the database system in several steps, including:
- Parsing the SQL statement and checking its validity
- Transforming the SQL into an internal representation, such as relational algebra
- Optimizing the internal representation and creating an execution plan that utilizes index information
- Executing the plan and returning the results

The execution of SQL is highly complex and involves many considerations, such as:
- The use of indexes and caches
- The order of table joins
- Concurrency control
- Transaction management
