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.

Question

1. Transform the diagram on the previous page into a relational model. All the relations in the
relational model should be in the third normal form. Show primary keys, referential integrity
constraints, and functional dependencies, as appropriate.
2. The following two changes are made to the Film entity in the ERD (Other parts of the ERD
remain the same). Revise your transformed relation (Film) and it should be in the third normal
form. Show referential integrity constraints, and functional dependencies as appropriate:
1) A new attribute, SHOW-TIME, is added to Film to describe the time period
in which a film can be played.
2) The following new functional dependency holds:

Explain three cases when a surrogate key should be generated in place of the main key of a relation.
What are three signals that a surrogate key should be generated for the primary key of a relation instead of using the main key?
25. In the relational model, relationships between relations or tables are created by using: a. composite keys b. determinants c. candidate keys d. foreign keys
Develop an Entity Relationships Diagram (ERD) based on the relational schemas in the 3NF for the starting relational schema in un-normalized form presented below. UNF:Order(OrderID, OrderDate, CustID, CustName, CustPhone, CCNum, CCExpDate, CCBank, BnkContName, BnkContPhone, CustEmail, OrderIP, SiteRefFrom, ShipStreet, ShipCity, ShipSt, ShipZip, OrderLineNum, ItemID, ItemName, ItemDesc, ItemQtyOrdered,ItemListPrice, ItemSalePrice, ItemQtyShip, ShipCharge, Tax, TotalDue)
Use the technique of normalization to validate the structure of your relational schema. Demonstrate that each of your relations is in third normal form (3NF) by displaying the functional dependencies between attributes in each relation. Note, if any of your relations are not in 3NF, this may indicate that your ER model is structurally incorrect or that you have introduced errors in the process of deriving relations from your model.
Please draw an relational ERD with multiplicities and all the attributes based on following description: ( Please identify the primary key in each entity.) An Adult Education Department runs various courses during the daytime and evenings, and at different times of the year. For example, ‘Spanish level 1’ is offered on Monday mornings, Monday evenings or Wednesday evenings, and runs over 25 weeks from October to March. On the other hand, ‘Introduction to Digging Up Your Ancestors’ only runs for 8 weeks, but is offered on Tuesday or Wednesday evenings from October to December, January to March, and April to June, with an optional field week in August. There is always a maximum number of places for each course offering, which is dependent on the individual teacher. For example, ‘Spanish level 1’ on Monday evenings may be limited to 20 places, but on Wednesday evenings the limit may be 25. Each course offering is only taken by one teacher, however teacher may take…
Consider the case of a many-to-one connection R between the entity sets A and B (see Figure 1). Consider the case in which the relationship generated from R is paired with the relationship created from A. In SQL, it is possible for attributes that are part of a foreign key constraint to be null. In SQL, explain how a limitation on the total involvement of A in R may be imposed by the use of non-null constraints.
PLz help with the following: Translate your ER diagram into a relational schema in the form of SQL DDLs. Choose appropriate data types for each attribute and include primary key and foreign key constraints, Check and Not Null constraints.
Suppose that A and B are two sets of entities connected by a relation R that has multiple one-to-one occurrences (see Figure 1). Think about a scenario in which R's generated connection is coupled with A's. SQL allows null values for attributes that are a part of a foreign key constraint. Give an example of how non-null constraints may be used in SQL to place a restriction on how much A can be involved in R.
