Hello!
There is a small data structure (2500 lines), and the problem is how and WHERE to store them?
Small piece:

"ФизМат": {
        "B009": {
            "code": "B009",
            "name": "Подготовка учителей математики",
            "max": "140",
            "min": " 107",
            "minWithQuota": " 95",
            "quotes": [{
                " (003 Каспийский университет технологии и инжиниринга имени Ш.Есенова (квота))": {
                    "max": "140",
                    "min": " 109",
                    "minWithQuota": " 93"
                }
            }, {
                " (005 Актюбинский региональный университет имени К.Жубанова (квота))": {
                    "max": "140",
                    "min": " 123",
                    "minWithQuota": " 121"
                }
            },....
"КазЛит/РусЛит": {...}

Answer 1

Where and how to store depends on where and how it will be used.
For example, you can store in a text file in JSON format.

Answer 2

Looks like a case for document-oriented databases
