Answer:
Case-based reasoning.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
Case-based reasoning is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it. It is typically based on cognitive science and artificial intelligence.

Explanation:
The arithmetic logic unit (ALU) performs mathematical, logical, and decision operations. It can be divided into the arithmetic unit (responsible for addition, subtraction, multiplication and division). And logic unit (responsible for comparing, selecting, matching and merging different data or information). The power and efficiency of the CPU depends on the design of the ALU.
Next up is the control unit (CU) which directs all the processor’s operations. It’s where the CPU reads and interprets requests from memory and transforms them into a series of signals (binary). Then it sends the operation to various parts of the laptop as instructed. The CU calls the ALU to perform the necessary calculations. It also coordinates all input/output devices to transfer or receive instructions.
The main job of the memory unit is to store data or instructions and intermediate results. It’s divided into primary memory and secondary memory to supply data to other units of the CPU. It allows the CPU to perform functions requested by programs like the operating system without having to ask RAM.
Another element of the CPU not depicted in the diagram is transistors. To carry out calculations, binary information (ones and zeros) is stored in these microscopic switches. They control the flow of electricity depending on whether the switch is ON or OFF. Signals turn off and on different combinations of transistors to perform calculations. A very thin silicon chip can contain several hundred million transistors.

Explanation:
Please find the screenprint and the VBA code. As shown in the screenprint, range B1 is used to enter the number of petals. If you want to use a different cell for petals input, then change the code accordingly.
Also, the VBA code is placed in the Sheet1 module. No new modules are inserted.
Screenprint: see attachment for screenshot
VBA Code:
Private Sub CommandButton1_Click()
Call daisyDecisions
End Sub
Private Sub daisyDecisions()
Dim remainder As Integer
Dim noOfPetals As Integer
noOfPetals = Sheet1.Range("B1").Value
remainder = noOfPetals Mod 2
If remainder <> 0 Then
MsgBox "He/She loves you!!!"
Else
MsgBox "He/She loves you not!!!"
End If
End Sub
