Salesforce Case Study 4: Suppose that in you Salesforce Developer Org there is an custom object table Session_Speaker containing field like Session_Date_c, Id and Session_c. Now you have to create a trigger on creation of that record that rejects multiple booking of the speaker sessions. Develop the code for Apex trigger in Apex programming language.
In order to make a strong case for the use of deep rather than shallow access, it is best to avoid arguments based on performance.
2) Draw an use case diagram according to the below scenario: MAIN FLOW • The user could be student and staff. • The user request for book, reserve a book and renew a book (although rare, the user enter invalid renewal) • The user can view the book information . At the same time, the user may search for book. The user pays for fine and also give feedback. • The user can also register as new user. • The librarian can add record, delete and updatate a book record (although rare, the librarian enter invalid ID) EXCEPTIOANAL CONDITION The user and librarian must be authenticated to finalize the process. It could be done through user login page, user authentication cookie ('remember me') or single sign on. Although rare, they enter invalid username and password. • The user must fill in up feedback form for giving feedback. • The user must fill in up registration form and get library card id for registering as new user. The librarian must update the record id for updating the book record. The…
Suppose you had an information/briefing session with college’s Chief Information Officer (CIO) on some of the key use cases of the Campus Access Control System (CACS). The CIO described the process that the student lab-access sub-system goes through to authorise student’s access to the laboratories. Essentially, the lab access sub-system interacts with CACS and retrieves a list of students that are authorised to access a particular lab. If the student who is currently swiping her access card is in this list, then the lab access sub-system will grant access, otherwise access is denied.Use Visual Studio modelling tools to create a Use Case Diagram and a Sequence Diagram for the above process as described.

3. Index records comprise search-key values and data pointers. Multilevel index is stored on the disk along with the actual database files. As the size of the database grows, so does the size of the indices. If single-level index is used, then a large size index cannot be kept in memory which leads to multiple disk accesses. Multi-level Index helps in breaking down the index into several smaller indices in order to make the outermost level so small that it can be saved in a single disk block, which can easily be accommodated anywhere in the main memory. Why is there an immense need to keep the index records in the main memory?
