Tecdoc Mysql New

The TecDoc database is the global standard for automotive spare parts data. Due to the sheer volume of data—often exceeding 40GB of raw text and millions of relationships—importing the "new" TecDoc catalog into a MySQL database presents significant performance challenges. This paper outlines the best practices for schema design, data import strategies, and query optimization to ensure a responsive parts catalog application.

This is the fastest way to ingest TecDoc data.

LOAD DATA LOCAL INFILE '/path/to/TOOF_ARTICLES.txt'
INTO TABLE articles
FIELDS TERMINATED BY ';' 
OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'
(art_id, @supplier_id, art_nr, @var_date)
SET supplier_id = TRIM(@supplier_id), 
    art_nr = UPPER(TRIM(@art_nr));

The Problem: Every quarter, TecAlliance changes linkage logic. The Solution: In the new MySQL setup, use soft foreign keys (no REFERENCES clause). Manage relationships via application logic and validation scripts. tecdoc mysql new

If you receive TecDoc data as SQL files or CSV exports, you might:

Edit /etc/mysql/my.cnf or /etc/my.cnf:

[mysqld]
innodb_buffer_pool_size = 8G          # 70% of RAM
innodb_log_file_size = 2G
innodb_flush_log_at_trx_commit = 2    # faster inserts
bulk_insert_buffer_size = 256M
tmp_table_size = 2G
max_heap_table_size = 2G
key_buffer_size = 512M

Indexes to add (after import):

CREATE INDEX idx_articles_supplier ON articles(supplier_id);
CREATE INDEX idx_vehicle_link_article ON vehicle_article_link(article_id);
CREATE INDEX idx_vehicles_make_year ON vehicles(make_id, from_year);

The "new" frontier involves MySQL 8.0's Document Store. Developers are starting to store TecDoc assemblies as JSON documents inside MySQL tables. This hybrid approach allows you to use SQL for relationships (Vehicle to Article) and NoSQL for the dynamic attributes of the part itself. The TecDoc database is the global standard for

Example of a future-proof query:

SELECT 
    v.car_name, 
    a.article_nr, 
    a.data->>'$.Diameter' as Brake_Disc_Size
FROM tecdoc_vehicles v
JOIN tecdoc_link_articles_vehicles l ON v.id = l.vehicle_id
JOIN tecdoc_articles a ON l.generic_article_id = a.generic_article_id
WHERE v.car_name LIKE '%BMW X5%' AND a.data->>'$.Diameter' > '300';
