Essential for the costs of a plan is the execution order of join operations in its operator tree, since the runtime of plans with different join orders can vary by several orders of magnitude. An exhaustive search for an optimal solution over all possible operator trees is computationally ...
Start Ups: They do focus on system design a lot ans in between questions on DBMS are frequently asked So, we need to be 100% prepared for it & best way is to follow the System Design Primer (resource given below) Questions always revolves around the type of DB, why this DB, why not...

Accurate peak power evaluation of query processing is fundamental to a power-aware DBMS running in large data centers. To estimate the peak power of the core operator join in query processing, the concept of CPU-boundedness was introduced, i.e., the ratio of CPU-intensive operations in unit ...

Logic design is the area of computer science that deals with the design of electronic circuits using the fundamental principles and properties of logic (see Boolean algebra) to carry out the operations of the control unit, the ALU, the I/O controllers, and other hardware. Each logical function...
