Excel で作成した際にはフィールド名だとわかるように最低限、太字で表示するなどします。データ型によってデータを扱う際に、何ができるのか、何をすべきかが決まってきます。すべてのデータにはデータ型が必要です。具体的には、テキストや数値、日付といった具合です。実際にデータを扱うようになるとデータ型にはさらに種類が多くあることがわかってきます。例えば、システムで利用するデータは多くがデータベースで管理されています。データベース内でデータはテーブルという表形式で管理され、テーブル内のフィールド設定は開発者が定義します。フィールド名が作成され、データ型が設定されています。従業員データの社員国籍 ID データを見てみましょう。データ型が「短いテキスト」、テキスト型であることがわかります。しかし、実際のデータを見ると数字のように見えませんか。次の点に注目してください。テーブル内のデータはデフォルトでは、数字は右揃えにテキストは左揃えに表示されます。しかし、左揃えに表示されている数値を見ると自動的にそれがテキストだと思い込んでしまうことがあります。このデータをエクスポートすると元のデータ型で保存されます。エクスポートしたデータを Excel で見てみましょう。「社員国籍 ID」列を見ると左揃えで表示され緑の旗も表示されています。そのうちのひとつをクリックするとその値が、テキスト型として保存されている数字であるということがわかります。繰り返しますが、このデータは左揃えでテキストですが、その他の列の数値はすべて右揃えです。元のデータベースの設定詳細まで確認できるわけではありませんがデータを見て何のデータ型であるかを判断することができます。例えば「色がフィールド名で、値が赤のデータは何ですか」と聞かれれば「単語」や「テキスト」と答える人が多いのではないでしょうか。「文字列」と答える人もいるかもしれません。「１」や「５」や「45,981」を見れば「数字」だという人が多いと思います。また「11/20/2025」というデータを見るとカレンダーや予定など「日付」と考えることが多いと思います。データを見てそれが何であるかを考えるときデータ型について考えることにつながります。 Excel 上で「11/20/2025」と「45,981」は同じデータ型です。違うデータ型のように見えるのはそれぞれの書式、フォーマットに違いがあるからです。見てみましょう。 B2 をクリックし上部にある「表示形式」メニューを見ると上から順に数字が並び「短い日付形式」の所に「2025/11/20」と表示されていることに気づくでしょう。 Excel 上で入力した数字が日付として解釈されてしまったという経験をしたことがあるという方もいるかもしれません。次に、セル上で分数を入力していると何が起こるかを見てみましょう。「1/4」と入力します。これは４分の１という意味で入力しています。しかし、Excel は日付だと解釈してしまいました。つまり分数として入力した数字を Excel は自動的に日付と判断し日付に適したフォーマットで表示してくれました。 Excel が行っていることはシリアル値と思われるデータを日付フォーマットで設定し表示しているということです。言い換えると、 Excel が日付を通し番号に変換し数学的に使えるようにしているのがシリアル値です。フォーマットを修正するにはフォーマットを数字に戻す必要があります。操作をご覧ください。セルをクリックし「表示形式」から「標準」または「数値」を選択します。小数点以下の桁数を減らします。データアナリストは一般的なデータ型を知っておく必要があります。具体的には、テキスト、日付、時刻、数値といったデータ型や、「真か偽」「『はい』か『いいえ』」を表すブール型です。使用するシステムやデータベースなどそれぞれにデータ型の種類や、数も異なります。テキスト型を例に見てみると Microsoft Access には短いテキスト、長いテキストという２つのデータ型があります。そしてデータベースには、テキストを表すデータ型がさらに数多く存在しています。現実には無意味なフィールド名や不適切なデータ型の設定により正しくデータが入力できないということがあることをデータアナリストや現場で働く人々は知っています。 "} </script>  </head> <body

データについて知っておくべき重要な３つの言葉があります。それは、フィールド名、データ型、値です。多くの人がデータとして見ているものは値です。値とは、私たちが入力し演算し、出力するものです。アンケートフォームなどで氏名の入力欄があれば氏名の値を入力します。この氏名という値はテキストデータです。フィールドとは列のことです。フィールドに格納する値によりどのようなデータ型を定義するかを決める必要があります。フィールドに適切なデータ型が設定され、正しい値を抜け漏れなく入力して利用します。しかし、日々扱うデータはフィールドが充分に検討されていないまま運用されていることも往々にしてあります。フィールドの名前も大切です。例えば、フィールド名に「名」、「姓」、「職種」といった具合に付けることができます。フィールド名はフィールド内で扱っているデータがどういったものかをイメージできるような名前を付けることが望ましいです。しかし、必ずしもそのようになっていないこともあります。フィールド名は、ヘッダとも呼ばれ通常は列の一番上の行に表示されます。 Excel で作成した際にはフィールド名だとわかるように最低限、太字で表示するなどします。データ型によってデータを扱う際に、何ができるのか、何をすべきかが決まってきます。すべてのデータにはデータ型が必要です。具体的には、テキストや数値、日付といった具合です。実際にデータを扱うようになるとデータ型にはさらに種類が多くあることがわかってきます。例えば、システムで利用するデータは多くがデータベースで管理されています。データベース内でデータはテーブルという表形式で管理され、テーブル内のフィールド設定は開発者が定義します。フィールド名が作成され、データ型が設定されています。従業員データの社員国籍 ID データを見てみましょう。データ型が「短いテキスト」、テキスト型であることがわかります。しかし、実際のデータを見ると数字のように見えませんか。次の点に注目してください。テーブル内のデータはデフォルトでは、数字は右揃えにテキストは左揃えに表示されます。しかし、左揃えに表示されている数値を見ると自動的にそれがテキストだと思い込んでしまうことがあります。このデータをエクスポートすると元のデータ型で保存されます。エクスポートしたデータを Excel で見てみましょう。「社員国籍 ID」列を見ると左揃えで表示され緑の旗も表示されています。そのうちのひとつをクリックするとその値が、テキスト型として保存されている数字であるということがわかります。繰り返しますが、このデータは左揃えでテキストですが、その他の列の数値はすべて右揃えです。元のデータベースの設定詳細まで確認できるわけではありませんがデータを見て何のデータ型であるかを判断することができます。例えば「色がフィールド名で、値が赤のデータは何ですか」と聞かれれば「単語」や「テキスト」と答える人が多いのではないでしょうか。「文字列」と答える人もいるかもしれません。「１」や「５」や「45,981」を見れば「数字」だという人が多いと思います。また「11/20/2025」というデータを見るとカレンダーや予定など「日付」と考えることが多いと思います。データを見てそれが何であるかを考えるときデータ型について考えることにつながります。 Excel 上で「11/20/2025」と「45,981」は同じデータ型です。違うデータ型のように見えるのはそれぞれの書式、フォーマットに違いがあるからです。見てみましょう。 B2 をクリックし上部にある「表示形式」メニューを見ると上から順に数字が並び「短い日付形式」の所に「2025/11/20」と表示されていることに気づくでしょう。 Excel 上で入力した数字が日付として解釈されてしまったという経験をしたことがあるという方もいるかもしれません。次に、セル上で分数を入力していると何が起こるかを見てみましょう。「1/4」と入力します。これは４分の１という意味で入力しています。しかし、Excel は日付だと解釈してしまいました。つまり分数として入力した数字を Excel は自動的に日付と判断し日付に適したフォーマットで表示してくれました。 Excel が行っていることはシリアル値と思われるデータを日付フォーマットで設定し表示しているということです。言い換えると、 Excel が日付を通し番号に変換し数学的に使えるようにしているのがシリアル値です。フォーマットを修正するにはフォーマットを数字に戻す必要があります。操作をご覧ください。セルをクリックし「表示形式」から「標準」または「数値」を選択します。小数点以下の桁数を減らします。データアナリストは一般的なデータ型を知っておく必要があります。具体的には、テキスト、日付、時刻、数値といったデータ型や、「真か偽」「『はい』か『いいえ』」を表すブール型です。使用するシステムやデータベースなどそれぞれにデータ型の種類や、数も異なります。テキスト型を例に見てみると Microsoft Access には短いテキスト、長いテキストという２つのデータ型があります。そしてデータベースには、テキストを表すデータ型がさらに数多く存在しています。現実には無意味なフィールド名や不適切なデータ型の設定により正しくデータが入力できないということがあることをデータアナリストや現場で働く人々は知っています。 </p> </div> </div> </section> </div>
