## 背景
15+
chatGPT 的诞生影响了很多行业, 数据库作为数据的集散地, 与机器学习结合有着天然的优势, PostgreSQL作为灵活可扩展插件的数据库, 除了老牌的madlib插件, 一直不火, 原因可能是流行门槛太高.
16+
17+
商家终于学乖了, 最近在业内也有一些厂家开始做端到端的机器学习产品, 例如postgresml.
18+
19+
就像elasticsearch, 做端到端的服务是使之火起来的原因之一.
20+
21+
postgresql其他端到端的服务还包括crunchydata出品的gis类产品: crunchy-spatial https://www.crunchydata.com/products/crunchy-spatial
22+
23+
https://github.com/postgresml/postgresml
24+
25+
PostgresML is an end-to-end machine learning system. It enables you to train models and make online predictions using only SQL, without your data ever leaving your favorite database.
26+
27+
Train and deploy models to make online predictions using only SQL, with an open source extension for Postgres. Manage your projects and visualize datasets using the built in dashboard.
28+
29+
从WEB端到数据库端、算法端全包含. 算法库使用rust开发, 效率和稳定性的保障.
30+
31+
https://postgresml.org/
32+
33+
Easily train and deploy online models using only SQL, with an open source extension for PostgreSQL.
34+
35+
例如:
36+
37+
```
38+
SELECT pgml.train(
39+
'My First PostgresML Project',
40+
task => 'regression',
41+
relation_name => 'pgml.digits',
42+
y_column_name => 'target',
43+
algorithm => 'xgboost'
44+
);
45+
```
46+
47+
postgresML使用的是MIT开源许可, 等于放弃一切权力.
48+
49+
postgresML部署参考:
