- The ______________ model is a simple but highly useful way to organize data into collections of two-dimensional tables called relations.arrow_forwardHow do views and materialized views differ in terms of performance and use cases?arrow_forwardCan the answer be done as a diagram and not the code behind the creating of the tables but the actual tables and attributesarrow_forward
- The term attribute refers to a of a table. Your answer When we talk about the table in more accurate details, for example this field, what is its data type and what is the domain of it like integer or text, this type is called view of data. Your answerarrow_forwardWrite down the all views of 4+1 View Model with the purpose, stakeholders and wayof representation of each viewsarrow_forwardIn this part you will be to map the EER schema design to a relational database schema, and create the tables corresponding to the relational schema using the MySQL. You will add to your report a listing of the CREATE TABLE statements. Specify as many constraints (key, referential integrity) as you can in the relational schema. You should state the choices you made during the EER-to-relational mapping, and the reasons for your choicesarrow_forward
- A data model is a collection of data description constructs. The main purpose of a data modeling is to assist in the understanding of the meaning (semantics) of the data and facilitate communication about the information requirements. Discuss FIVE (5) evaluation criteria for a good data model. [Hint: As a database designer, you have to interview customers, you are required to include questions you may ask to customers in your answers]arrow_forwardWhen utilizing subtype associations, it is important to discuss the database table options that are available.Decide on the design you want to use and discuss the challenges that arise as a result of it.arrow_forwardThe various database table choices should be discussed when dealing with subtype associations.Discuss the issues that are relevant to the layout you decide to utilize.arrow_forward
- Tasks: Considering the following E-R diagram, you need to translate it into a relational database and add some data to the tables. a) Write SQL statements to create the corresponding relations and capture as many of the participation and cardinality constraints as possible. Make sure that the data type and size for each attribute are appropriate. b) If some constraints in the diagram cannot be captured, explain why. c) Write SQL statements to insert at least two tuples for each table task name number ssn phone administrators O deptName dob Employees Caddresses salary staff's hourlySalary number M name Places N Orders M Contains N Items description P status number ID expShipDate qty deliveryDate name qtyInStock CunitCost actualShipDate salePrice email Street Customers city Addres statearrow_forwardCreate a diagram for a database with at least 5 tables. This should show your table names and column names. Show the relationships between the tables. Write a statement explaining your database design (why did you use the tables that you did). Create a database in Access based on your diagram. Include all tables in your diagram. Tables should each have a minimum of 5 rows. Create 5 SQL statements using your database. At least 2 of these should be manipulation statements (insert, update, etc). The others should be select statements. Explain what your sql statements do and how they would be useful to your database.arrow_forwardCreate a relational model with foreign and primary keysarrow_forward
