Write a program that views, inserts, and updatesstaff information stored in a database, as shown in Figure a. The View buttondisplays a record with a specified ID. The Insert button inserts a new record. TheUpdate button updates the record for the specified ID. The Staff table is createdas follows:create table Staff (id char(9) not null,lastName varchar(15),firstName varchar(15),mi char(1),address varchar(20),city varchar(20),state char(2),telephone char(10),email varchar(40),primary key (id));
Write a program that generates student records in a database file. Your program should be able to generate at least 10 records. The format in the database should be: student name, student id The first student id should be 20180001, second id will be 20180001 and so forth. Show screenshot of script
When you create a case in EnCase you add your information either by a template or enter it individually for each case. Where is this header information contained? It is stored in the header in the first evidence file since it does not have to be written to again It is stored in each data block before the CRC for the next file It is stored in the last section of the evidence file right before the MD5 hash It is stored in the header in each of the subsequent evidence files added to the evidence file
