- When contrasted with other data structures, such as a linked list or tree, this one has a number of advantages.Explain the concept of "lazy loading" in the context of data binding for optimizing the loading of resources in a web application.Computer Science It is needed to design a database system for a pharmacy. The pharmacy contains many different items. Items may be products or medicines. Medicines are classified into different types either bills, injection, capsule or drugs or any combination of them. An item must be supplied by only one supplier. A supplier may supply many type of items. A customer may order many items. The pharmacy has a unique name, address and more than one telephone. The doctor can prescribe one or many medication, injections can not be bought without a doctor prescription. You are requested to draw the EERD diagram for the described system You are required to write down any assumptions made from your side You should add the attributes and cardinality for all the entities You are required to model the EERD into relational model
- C language Identify what are the fields required to develop a Medical Appointment System. From that fields you need to perform the following operations using any data structures elements to develop the system. Your program must include these functions: Insert a new record in the appropriate position Remove a record when ID is given ● • Update a record based on ID given • Find a record based on ID given List all records in alphabetical order You should use linked list and stack and queue You should include comments in your program. ** Kindly don't copy the code from the internet because it's incorrect and doesn't include linked list, stack, and queue ** Thank you..1. Priority queue store tasks using a partial ordering based on priority. Explain this statementSafe Datalog Rule: A Datalog rule is of the form:p :- q1, ..., qn. where n>0 and p is a positive atomic formula and q1, ..., and qn are positive or negative atomic formulas. A positive atomic formula is of the form:r(x1, ..., xm) and a negative atomic formulas of the form:not r(x1, ..., xm) where m>0 and r is a relation name and x1 , ..., xm are either numbers or variables. Relation names and variables are made up of alphabetic letters or digits and start with a lower-case alphabetic letter. Even though the variables are made up of lower and upper-case letters, these should be considered case-insensitive. For example, cno, CNO, cNO, etc all should be treated as the same variable. Some examples of Datalog rules are given below: ancestor(x1, y1) :- parent(x1, y1). teaches(tno,cno) :- faculty(tno), course(cno), assigned(tno,cno). p(x,y) :- q(2,x), r(u,45,z), s(a,b,22). p(x,y,z) :- q(x), not r(y,20), s(x,z). A Datalog rule is considered “Safe” if all variables that appear to the left…
- Customers at a motor vehicle licence renewal office is assigned a number on arrival, and customers are served in the order of their allocated numbers.A Priority Queue is selected as the data structure to maintain the waiting list. Why?Explain collaborating on To-Do List?Software Engineering The recruitment agency TEMPO proposes internship employees for enterprises for a periodof time. An internship employee is a temporary employee that will be recruited for a periodof time. You must develop a database application in order to satisfy these specifications: The enterprises (id, name, address and phone number) define the posts for which theyneed one or many employees. A post is defined with a label, a daily remuneration, thestart date, the end date and the number of employees for this post. A post needseventually diploma(s) and a list of many skills. An internship employee is described by a ssn, first name, last name, an address, aphone number, his/her diplomas (we store for each diploma the year when it isobtained) and his/her skills. An employee could be recruited for one or many posts. This recruitment of anemployee for a given post is validated by a chief (ssn, first name, last name, address)designated by the enterprise. This chief is unique to an…
- Computer Science Can someone help me create a program that is a library management system? So, the program will manage a library collection of books, allowing the user to add books, check them out, and return them. possibly use data structures such as linked lists or hash tables which will keep track of the availability of the books. demonstrate its function and discuss your experiences in creating it. Topics worthy of discussion include details of the implementation itself (language choice, class design, etc), difficulties that you faced in implementing it (learning new techniques, significant errors encountered, etc), and maybe a project post-mortem discussing whether or not you would do anything differently, knowing what you do about it at the end (e.g. using a linked list instead of an array). c++The Driver Relationship considered that working on both DRIVERS and ACTIVE_DRIVERS tables is difficult and too much work. Therefore, the team wants you to remove the table for the active drivers.Make a Flight Management System in C++ having following features: Two queues each for landing and takeoff (Use array as queues) Manage arrivals Manage departures Manage emergencies (priorities) Load balancing View Reports Arrival Information class includes: Flight Id Fuel Destination Arrival Date and Time Landing Time Waiting Time Runway Id Record all related information. System should assign Runway automatically based on the load of landing runways With time fuel decreases and waiting time increases Departure Information class includes: Flight Id Destination Scheduled Departure Date and Time Actual Departure Date and Time Waiting Time Flight Status Runway Id Record all related information System should assign Runway automatically based on the load of runways With time, waiting time increases. Reports class includes: Cancel Flights Emergency landings ( Get flight id to land it on emergency runway (implement priority queues) ) Dont use pointers please.
