Transaction Processing

Transaction processing is a computational style generally performed by server computers, which supports interactive applications (apps). Transaction processing is also known as information processing, which divides the work into indivisible and individual operations called transactions. The transaction is a set of tasks; a single task is considered as the minimum processing unit that cannot be divided again.

In the hierarchy of data, what is the difference between a data attribute and a data item? What is the domain of an attribute?
I understand the intentions of a database, being to streamline the data record-keeping of any organizations. And I understand the hardware needed to do such. The area I find myself the most lost in is the idea of programming the rules and structure of a database. In my head a database is a chart (or multiple charts) with fields that is used to store records. And then those records stored in one chart intertwine with other charts of course so we need to have relationships between the charts. Where I get lost is in the thought of programming a structure for the data to fit in. Are we making metaphysical locations to store data or are we just writing relationshipds between data that is stored on a plethora of different options?

Assignment Brief: Some of the most difficult decisions that you face as a database developer are what tables to create and what columns to place in each table, as well as how to relate the tables that you create. Normalization is the process of applying a series of rules to ensure that your database achieves optimal structure. Normal forms are a progression of these rules. Each successive normal form achieves a better database design than the previous form did. Based on your understanding for the various normal form respond to the following problems and provide the optimal answer/solution. Problem#1: 1st Normal Form (1NF) Consider the Students table, with the primary key underlined, and the following data: Students: Alpha 100111 Email doe@usna.edu Name Courses GradePoints NN204, SI204, IT221 SM223, EE301 SI204 John Doe 2,3,3 Matt Smith 092244 113221 smith@usna.edu black@usna.edu 4,4 Melinda 3 Black NN204, SI204, IT221 090112 Tom Johnson Johnson@usna.ed 4,2,3 u a) Is the Students table…
