== Technology Stack ==
The application utilizes the following technologies:

{| class="wikitable"
! Component !! Technology
|-
| Runtime !! GnuCOBOL 4.0, Linux
|-
| SQL pre-processor !! GixSQL (translates EXEC SQL … END-EXEC to GIXSQLExec calls)
|-
| Database server !! PostgreSQL 11.22, localhost:5432
|-
| Database schema !! primes
|}

[[Technology Stack|More details]]

== Component Architecture ==
The application consists of the following components:

<pre>┌─────────────────────────────────────────────────────┐</pre>
[[Component Architecture|More details]]

== Business Requirements ==
The system is designed to meet the following business requirements:

=== BR-01: Prime Number Generation ===
The system shall compute all prime numbers from 3 up to 999,999,999 using a trial-division algorithm and store each confirmed prime in the database.

=== BR-02: Prime Number Reporting ===
The system shall produce a formatted printed report listing all primes currently stored in the database.

[[Business Requirements|More details]]

== Database Objects ==
The application interacts with the following database objects:

{| class="wikitable"
! Object !! Type !! Schema !! Owner !! Definition
|-
| primes !! Schema !! — !! primes_user !! Container schema
|-
| asc_ident !! Sequence !! primes !! primes_user !! INTEGER, START 1, INCREMENT 1
|-
| primes !! Table !! primes !! primes_user !! See below
|}

[[Database Objects|More details]]

== Output File Specification ==
The output report is generated in the following format:

{| class="wikitable"
! Property !! Value
|-
| Filename !! primes.prt
|-
| Organisation !! Line-sequential
|-
| Record length !! 132 characters
|}
