To create tables in SQL, utilize the following code:

CREATE TABLE Person with customer_ID INT as the primary key along with columns first_name, last_name , address, city, state and zip which cannot be empty. Additionally, include birth_day under DATE.  

The next step would be to INSERT values into the above mentioned 'Person' table. The sample values I provide give information such as the ID of the customer- John Doe being assigned a value of 1 along with his address, state or even zip code. Similarly, we have records for Jane Doe, Bob Smith and Samantha Johnson variously spread out all over the country.

Adding an extra column with birth_day under DATE can be done using ALTER TABLE Person ADD COLUMN birth_day date code.

Thereafter, UPDATE Person SET birth_day= '2000-01-01' needs to run so that customer's birth day gets updated automatically.

Create another table called "Gifts" with gift_id being assigned as PRIMARY KEY INTEGER data type and gift_desc described under

Further insert gifts such as pool table, guitar, smartphone, watch and camera into the Gift table that was just created.

Making use of JOIN operations, connect the Customers and Gifts tables  through referential integrity by utilizing FOREIGN KEY constraints based on both customer_id and gift_id in the third newly generated table - Birth_days. ForeignKey connects each record across two tables using these shared columns to generate unique results.

To display all three interlinked tables together presented in unison, SELECT person's first name, last name and matching gift descriptions, only customers who have received birthday gifts are shown. To further enhance understanding, COUNT(*), used to count up the total occurrences treated equally regardless if they are Red vs Green etc, lists down number of gifts each person has been given. Finally, resorted numerically according to number of gifts per gender descending order LIMIT 1%.

The code is performing a load-store operation in ARM assembly language.

The LDURB instruction loads a byte from the memory location pointed to by the register X3 and stores it in the register X10. The STUR instruction stores the value in register X10 to the memory location pointed to by the register X7, with an offset of 8 bytes.

Assuming that the machine is big-endian, the byte at address 0x40000000 will be loaded into the least significant byte of the register X10. The remaining 7 bytes of the register will be zeroed out.

Therefore, the value stored in X10 will be 0x00000000000000eb. This value will then be stored at the memory location pointed to by X7 with an offset of 8 bytes, i.e., at address 0x40000008.

So, the value stored in address 0x40000008 will be 0x00000000000000eb.

File-based data management is a method of storing data in individual files. Each file is created and managed by the application that created it. This approach is simple and easy to understand, but it can be inefficient and difficult to manage when the amount of data grows.

Database-based data management is a more sophisticated approach that stores data in a central repository, or database. The database is managed by a database management system (DBMS), which provides a number of features that make it easier to store, retrieve, and update data. These features include:

Data integrity: The DBMS ensures that the data in the database is consistent and accurate.

Data security: The DBMS can be configured to control who has access to the data and what they can do with it.

Data performance: The DBMS can optimize the way data is stored and accessed, which can improve performance.

Data scalability: The DBMS can be scaled up to handle large amounts of data.

Database-based data management is more complex than file-based data management, but it offers a number of advantages, including:

Efficiency: Databases can be more efficient than files when it comes to storing and retrieving large amounts of data.

Flexibility: Databases can be more flexible than files when it comes to changing the structure of the data.

Security: Databases can be more secure than files, as they can be configured to control who has access to the data and what they can do with it.

Performance: Databases can be more performant than files, as they can be optimized for the way the data is being used.

Scalability: Databases can be scaled up to handle large amounts of data.

Which approach is right for you?

The best approach for storing and managing your data depends on a number of factors, including the size of your data, the number of users, and the level of security you need. If you have a small amount of data and a few users, file-based data management may be sufficient. However, if you have a large amount of data, multiple users, or need a high level of security, database-based data management is the better choice.
