+# 日次バッチ処理前DBダンプ取得　
+
+## 概要
+
+日次バッチ処理前DBダンプ取得処理。
+
+## 環境情報
+
+- Python 3.9
+- MySQL 8.23
+- VSCode
+
+## 環境構築
+
+- Python の構築
+
+  - Merck_NewDWH 開発 2021 の Wiki、[Python 環境構築](https://nds-tyo.backlog.com/alias/wiki/1874930)を参照
+    - 「Pipenv の導入」までを行っておくこと
+  - 構築完了後、プロジェクト配下で以下のコマンドを実行し、Python の仮想環境を作成する
+    - `pipenv install --dev --python <pyenvでインストールしたpythonバージョン>`
+    - この手順で出力される仮想環境のパスは、後述する VSCode の設定手順で使用するため、控えておく
+
+- MySQL の環境構築
+  - Windows の場合、以下のリンクからダウンロードする
+    - <https://dev.mysql.com/downloads/installer/>
+  - Docker を利用する場合、「newsdwh-tools」リポジトリの MySQL 設定を使用すると便利
+    - 「crm-table-to-ddl」フォルダ内で以下のコマンドを実行すると
+      - `docker-compose up -d`
+      - Docker の構築手順は、[Docker のセットアップ手順](https://nds-tyo.backlog.com/alias/wiki/1754332)を参照のこと
+  - データを投入する
+    - 立ち上げたデータベースに「src05」スキーマを作成する
+    - [ローカル開発用データ](https://ndstokyo.sharepoint.com/:f:/r/sites/merck-new-dwh-team/Shared%20Documents/03.NewDWH%E6%A7%8B%E7%AF%89%E3%83%95%E3%82%A7%E3%83%BC%E3%82%BA3/02.%E9%96%8B%E7%99%BA/90.%E9%96%8B%E7%99%BA%E5%85%B1%E6%9C%89/%E3%83%AD%E3%83%BC%E3%82%AB%E3%83%AB%E9%96%8B%E7%99%BA%E7%94%A8%E3%83%87%E3%83%BC%E3%82%BF?csf=1&web=1&e=VVcRUs)をダウンロードし、mysql コマンドを使用して復元する
+      - `mysql -h <ホスト名> -P <ポート> -u <ユーザー名> -p src05 < src05_dump.sql`
+- 環境変数の設定
+  - 「.env.example」ファイルをコピーし、「.env」ファイルを作成する
+  - 環境変数を設定する。設定内容は PRJ メンバーより共有を受けてください
+- VSCode の設定
+  - 「.vscode/recommended_settings.json」ファイルをコピーし、「settings.json」ファイルを作成する
+  - 「python.defaultInterpreterPath」を、Python の構築手順で作成した仮想環境のパスに変更する
+
+## 実行
+
+- VSCode 上で「F5」キーを押下すると、バッチ処理が起動する。
+- 「entrypoint.py」が、バッチ処理のエントリーポイント。
+- 実際の処理は、「src/jobctrl_dbdump.py」で行っている。
