URS shall provide a clear list and description of all applicable client requirement to be fullfilled by the manufacturer of a machine equipment. A comprehensive and well written URS is the base for the machine development process and will help clarifying the client need and aswell save time and resources during the development by setting clear goals. The FDS Functional Design Specification is written on the base of URS documen t in order to describe how the design of the newly developed machine is going to fullfill the requirement of the client.
The FDS provides the basis of the design of the system and will be used aswell to verify and validate the system during the testing, ensuring all the required functions are present and that they operate correctly. FDS should details all the functions, operator interactions control and sequencing associated with the system, thus allowing the user to confirm, before the system is developed that the proposed solution fully meets its requirements.
Adapter gives the opportunity for the classes with incompatible interfaces to work together. Application: This pattern will be used in the Student Registration system when displaying information from the database.
This technique will provide the opportunity for the system users to experiment the software to a certain extent during the development process. Get Username and Password 2. Then login successful 4. Else login failed 5. End If.
Student login to account 2. Student login account 2. Select exam details option 3. Then view previous semester result preview 4. Select student subject option 3.
Select academic year and the semester 4. Guest login account 2. Enter relevant Index number and Password 3. IF Index number is equal to the entered Index number and the Password is equal to entered Password 4. Then preview student performance 5. ELSE Print incorrect password or index 6. Back to step 2 7. EXIT Admin login to account 2. Select admin selection option 3. Admin login account 2. Super user login to system 2.
Normalization usually involves dividing a database into two or more tables and defining relationships between the tables. The objective is to isolate data so that additions, deletions, and modifications of a field can be made in just one table and then propagated through the rest of the database via the defined relationships. For example, in a Student list, each table would contain only one email field. So, for example, if two tables both require an email field, the email information would be separated into a separate table, and the two other tables would then access the email information via a password field in the student table.
Any change to a email would automatically be reflect in all tables that link to the student table. Deletion anomalies — Deletion anomalies occur when we delete data from flawed schema. Insertion anomalies — Insertion anomalies are occur when we try to insert data into flawed Table. Update anomalies — Update anomalies occur when we change data in a flawed schema. In second Normalization tables have changed as following.
One table divide into several tables. For the third normalization also requirements have satisfied. There for now all the tables have satisfied the requirements in First, Second, and third normalization.
The statements specified in the SQL trigger are executed each time an SQL insert, update, or delete operation is performed. An SQL trigger may call stored procedures or user-defined functions to perform additional processing when the trigger is executed.
But for further validations functions we use php. Using php greatly increases security and usability. JavaScript will detect empty fields of a form, and php will be used to determine whether inputs are met some per-defined rules to insure only desired inputs are stored in the database.
Detecting and avoid accepting erroneous inputs before storing in the database, will make system more efficient. Rules to make sure user enters a correct E-mail address: 1. Input e-mail address must contain a sign and at least one dot. Also, the must not be the first character of the email address, and the last dot must be present after the sign and minimum 2 characters before the end.
Php will be used to ensure that these rules are met, while entering an E-mail address. Few instances we hope to use validations 1. On all text inputs, check boxes to ensure user fill all the required fields. E-mail address validations mentioned above 3. Input date validation, to make sure entered date is not likely to be an unacceptable one. System will use simple but informative error messages to inform user what is wrong with a certain operation.
The type of the error will be stated top of the error message, enabling user to understand quickly what caused the problem. Warnings will contain the same characteristics of Error messages but will clearly display the type of it. Occupationally system will display some useful tips and trick for the user.
This will reduce user's time to figure out everything on their own. Allow users to use either the keyboard or mouse flexible Users will be able enter data and navigate using any method, either keyboard or mouse. Scrolling, Selecting 2. It may be preferable to create one or more component diagrams which detail the planned tasks to be performed and detailing the various interactions.
The Information you need, provided in an easy to understand visual format. Software Design Specification. The exact way to store plugin data will be decided in the implementation stage.
Customer changes his requirements endangering the project's end date, or the project is carried out not comply with the customer. Increase cooperation and coordination with customer expectations. In addition, the development team will work flexibly so that any changes to the customer will be easy to carry out. System that should help develop not fulfill all our expectations of them.
