Explanation:
Both Primary Key and Candidate Key are the attributes that are used to access tuples from a table. These (Primary key and Candidate key) are also can be used to create a relationship between two tables.
- A Candidate Key can be any column or a combination of columns that can qualify as a unique key in the database. Each Candidate Key can qualify as a Primary Key.
- A Primary Key is a column or a combination of columns that uniquely identify a record. The primary key is a minimal super key, so there is one and only one primary key in any relationship.
<em> The main difference between them is that a primary key is unique but there can be many candidate keys. </em>
I hope you find this information useful and interesting! Good luck!
Pressing enter two times I’m pretty sure that’s right cuz like it does nothing when I do it. It’s either that or idk up to u to take an answer from someone who has bad grammar
Question
Student presentation concepts from another source
Letitia - a step-by-step process of breaking down glucose into energy
Mana - repeating process of the steps of the cell division, going from interphase to division, and back to interphase.
Paul - a series of organisms that show similar characteristics and compare them to those that do not
Which best describes the SmartArt graphic layout each student should use?
Answer:
Letitia would use a process, Maria would use a cycle, and Paul would use a relationship.
Explanation:
Letita's assignment requires her to show how glucose can be broken down into energy, this requires a series of steps in s linear fashion, meaning it would be best suited to a process-style diagram.
Marta's project involves showing the steps of the cell cycle: the clue is in the name. This process is not linear, and instead repeats itself, meaning it fits to a cycle diagram (i.e. a circular diagram)
Paul is comparing and contrasting different organisms. Therefore, he should use a relationship diagram to show shared characteristics as well as features that differ.
Answer:
The answer is " Uninitialized data segment
".
Explanation:
It (memory map) field whenever a C program is locked to run, the kernels must allocate information into 0 or null pointer in this section until the process runs. This variable, that is outside of any function, has been stored in uninitialized data item by the C statement (like, "long amount[1000];").
If we did not declare the data segment, it also called bss, in which all block which begins with the symbol and is called for an old assembly language operator.
