Write an ALTER TABLE statement that adds two new columns to the Products table created in exercise 2.

Add one column for product price that provides for three digits to the left of the decimal point and two to the right. This column should have a default value of 9.99.

Add one column for the date and time that the product was added to the database.

ALTER TABLE Products

ADD Price DECIMAL(5,2) DEFAULT 9.99

ADD TimeAdded DATETIME

Explanation:

ALTER TABLE is the alter table statement with the name of the table being altered as the Products table. Then you ADD the column's name you're adding, which is a decimal with 5 points of precision, 3 to the left of the decimal and 2 to the left, represented by DECIMAL(5,2) and a default value of 9.99. Lastly, the TimeAdded that a product was added can be simply a DATETIME typed column.

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
