Each user of the computer system that uses computer services has at least a. 1program b. 2programs c. 3programs d. 4programs

2. Web development languages and tools (a) List at least one web development language (like Javascript) / web development tool (like Dreamweaver or maybe WordPress) that you have some knowledge and explain. If you know many of them, then limit to at most 3 (languages + tools + ...) to explain (b) Compare at least two web languages / tools and list their pros and cons (this is just like comparing C#, Java, Python, MATLAB, C when you are doing your report assignment. So say why do you pick Python, but not C#, in this case you are comparing Python and C#)).

Using concrete examples, please describe the steps involved in conducting an examination of a software application's underlying structure.

2- Design a system which keeps track of the jobs that it is performing an a company. • Each job is of a certain type, which is also identified by a type name. • Each job performed is given a number, a starting date and a promised finishing data. The customer of a job is noted. Any job of a given type is done in one or more steps, each of which is identified by a code and name. The steps are numbered as 1, 2, .... The average time to complete a step is also recorded. • It is possible for a given job step to be used in several types of jobs. When a job is accepted, the required steps to complete the job are scheduled and the estimated start and completion dates are recorded for each step. • What are the entities in this database and what are their attributes? What are the keys? What are the relationships and their attributes? Indicate both the cardinality and participation of each relationship. Draw an extended entity-relationship (EER) diagram for this database.
