Преглед на достапни ентитети во Person табелата

Цел:

На најавениот корисник му се овозможува преглед на сите Person ентитети кои се достапни во базата на податоци на апликацијата, и детален преглед на нивните типови на извештаи.

Главната идеја

Со ова, се избира конкретно еден ентитет од понудените на почетната табела. Потоа, од кога ќе биде кликнато неговото име, соодветно се редиректира на друга страна, каде од базата се извлечени соодветно сите типови на извештаи за корисникот и прикажани во посебни и јасно оделени секции на екранот.

Дополнителен дел со статистики

Овој дел прикажува статистики за сите видови извештаи поврзани со избраната личност. Статистиките се прикажани во долниот дел од страницата и даваат преглед од сите извештаи.

SQL queries кои се користат за да се извлечат податоците

1. Со овие квериња се добиваат извештаите за дадената персона и се прикажуваат да бидат видливи за корисникот преку DTO објекти (со цел да може да се уредат колоните по избор, а не сите).

--academic reports

SELECT r.report_id, academic_field, description_of_report, i.name, i.type, i.address, i.year_established
            FROM report r
            JOIN academicreport ar ON ar.report_id = r.report_id
            JOIN institution i ON i.institution_id = ar.institution_id
            WHERE r.person_id = :personId

--employment reports

SELECT r.report_id, summary, er.start_date, er.end_date, job_role, income_per_month
            FROM report r
            JOIN employmentreport er ON er.report_id = r.report_id
            WHERE r.person_id = :personId

--medical reports

SELECT r.report_id, summary, next_control_date, d.short_description, d.therapy, d.severity, d.is_chronic,
                   doc.name, doc.surname, doc.specialization
            FROM report r
            JOIN medicalreport mr ON mr.report_id = r.report_id
            JOIN medicalreport_diagnosis mrd ON mr.report_id = mrd.report_id
            JOIN diagnosis d ON mrd.diagnosis_id = d.diagnosis_id
            JOIN doctor doc ON doc.doctor_id = mr.doctor_id
            WHERE r.person_id = :personId

--criminal reports

SELECT r.report_id, label, severity_level, location, resolved, descriptive_punishment
            FROM report r
            JOIN criminalreport cr ON cr.report_id = r.report_id
            JOIN crimetype ct ON cr.crime_type_id = ct.crime_type_id
            WHERE r.person_id = :personId

2. Со ова квери ќе се извлечат сите статистикит, ќе се пресметаат соодветно некакви операции, и доколку се добие резултат истиот ќе се прикаже во соодветната редица, во спротивно ќе даде некаква лабела дека не е пресметано/пронајдено нешто.
