図1は、本実施形態に係るデータ処理システム1の構成を示すブロック図であり、特に、サーバー50の構成を詳細に示す。
本実施形態では、データ処理システム1は、商取引を行う店舗Lで、商取引に関する会計処理を行うPOS(Point of Sales)システムとして機能する。データ処理システム1が適用される対象の店舗Lは、商品(サービスを含む)を提供して対価の支払いを受ける事業所であり、データ処理システム1は対価を計算し支払いを受け付ける会計処理を実行し、実行した会計処理に関する情報を保存する。
データ処理システム1は、POS装置10、及び、POS装置30を含み、POS装置10、30はそれぞれ通信ネットワークNでサーバー50に接続される。
データ処理システム1は、サーバー50が提供するPOSアプリケーション62(ウェブアプリケーション)を、処理装置11、及びタブレット31のそれぞれがウェブブラウザーにより実行して、POS装置としての機能を実現するWebPOSシステムである。
POS装置30は、タブレット31(端末装置)、記録装置41、バーコードスキャナー47、カスタマーディスプレー48、及び、キャッシュドロアー49を備える。タブレット31は、平板状の本体を有する、いわゆるタブレット型コンピューターである。タブレット31は、通信ネットワークNでサーバー50に接続して、サーバー50との間で各種データを送受信する。
POS装置10及びPOS装置30の構成については後述する。
本実施形態では、店舗Lに後述する通信装置5を設置し、通信装置5が通信ネットワークNに接続する構成を一例として示す。この構成では、POS装置10の処理装置11及びPOS装置30のタブレット31は、通信装置5を経由して通信ネットワークNに接続する。従って、端末通信路N1及びサーバー通信路N2は、少なくとも通信装置5と通信ネットワークNとを繋ぐ区間では共通の通信回線上にあるが、論理的には独立した通信路といえる。例えば、処理装置11とタブレット31とが別の通信装置を経由して通信ネットワークNに接続する構成も、勿論実現可能である。
より詳細には、タブレット31は、端末通信路N1の通信状態を判定する条件である端末通信条件を有する。端末通信条件は、予めタブレット31に設定され、タブレット31が生成し、或いは、タブレット31が他の装置から取得するなど、何らかの方法でタブレット31に与えられる。処理装置11は、サーバー通信路N2の通信状態を判定する条件であるサーバー通信条件を有する。サーバー通信条件は、予め処理装置11に設定され、処理装置11が生成し、或いは、処理装置11が他の装置から取得するなど、何らかの方法で処理装置11に与えられる。端末通信条件は、端末通信路N1の通信状態が、通信を実行可能な状態であるか否かを判定する基準または指標となるデータを含む。サーバー通信条件は、サーバー通信路N2の通信状態が、通信を実行可能な状態であるか否かを判定する基準または指標となるデータを含む。データの具体例としては、端末通信条件は、パケット欠損率、伝送遅延時間、ノイズ比率、エラー訂正の実行状態等が挙げられる。端末通信条件、及び/又はサーバー通信条件は、サーバー50がタブレット31及び/又は処理装置11に送信してもよい。
サーバー通信部55は、通信ネットワークNに接続し、サーバー制御部51の制御に従って、POS装置10との間、及び、POS装置30との間でデータを送受信する。
データ記憶部61は、アプリケーション実行部52が実行するPOSアプリケーション62、及び、POS装置10、30に送信するHTML(HyperText Markup Language)ファイル63を記憶する。
サーバー側マスターデータ67は、会計処理に用いるデータを蓄積する。例えば、商品の識別情報に対応する商品の単価を含む、PLU(Price Look Up)データベースを含む。商品の識別情報とは、例えば、バーコードスキャナー27、47が読み取る商品のバーコードのデータであり、いわゆるPLUデータである。また、サーバー側マスターデータ67は、商品の販売条件等に関するデータを含んでもよい。
処理装置11及びタブレット31は、後述するようにHTMLファイル63をウェブブラウザーで処理し、スクリプトの機能でサーバー50に対するデータの送信、及びサーバー50が送信するデータの処理を実行する。
処理装置11またはタブレット31が、POSアプリケーション62の機能により会計処理を行った処理結果を送信し、この処理結果をサーバー通信部55が受信した場合に、アプリケーション実行部52は、受信する処理結果に基づいてサーバー側売上データ66を更新する。
図2に示すように、POS装置10、30が設置される店舗Lには通信装置5が設置される。通信装置5は、広域ネットワークと店舗L内のネットワークとを接続する装置であり、例えば、スイッチ、ルーター、ゲートウェイサーバー等である。通信装置5の広域ネットワーク側は、有線の通信回線または携帯電話網等の無線通信回線で通信ネットワークNに接続する。通信装置5のLAN側のインターフェイスは、Ethernet(登録商標)等の有線LANインターフェイスや、IEEE802.11の無線LANインターフェイス、Bluetooth(登録商標)インターフェイスを含む。本実施形態では、通信装置5の有線LANインターフェイスに処理装置11が接続し、無線LANインターフェイスにタブレット31が接続する。通信装置5は、処理装置11とサーバー50との間の通信、及び、タブレット31とサーバー50との間の通信を中継する。
記録装置41は、タブレット31の制御により、プリンターユニット45でレシートを印刷するプリンターである。記録装置41は、記録装置制御部42、記録装置通信部43、デバイス接続部44、及びプリンターユニット45を備える。デバイス接続部44にはバーコードスキャナー47が接続し、プリンターユニット45にはカスタマーディスプレー48及びキャッシュドロアー49が接続する。
デバイス接続部44は、バーコードスキャナー47が出力する読取結果に基づきPLUデータを生成して、記録装置制御部42に出力する。
POS装置30のブラウザー実行部33は、上述したように、予め設定されたアクセス先のデータに従って、サーバー50に対してHTMLファイル63の送信を要求する(ステップS11)。サーバー50のアプリケーション実行部52は、HTMLファイル63の送信の要求を受信して(ステップS21)、HTMLファイル63を送信する(ステップS22)。
その後、POS装置30を操作するオペレーターが、バーコードスキャナー47を操作して、商取引の対象となる商品のバーコードを読み取る(ステップS13)。デバイス接続部44は、バーコードスキャナー47が出力する読取結果を取得し(ステップS14)、PLUデータを生成してブラウザー実行部33に出力する。ブラウザー実行部33は、PLUデータをサーバー50に送信してマスターデータ送信要求を行う(ステップS15)。
1回の会計処理で複数の商品を処理する場合、データ処理システム1は、図3(A)のステップS13~S17及び図3(B)のステップS22~S25の処理を繰り返し実行する。
処理装置11は、プリンターユニット19による印刷の制御、及び、データ処理を実行する処理装置制御部12を備える。処理装置制御部12は、処理装置通信部17、デバイス接続部18、プリンターユニット19、補助記憶部20、及びデータ記憶部23に接続する。POS装置10が備えるデバイスのうち、モニター26及びバーコードスキャナー27はデバイス接続部18に接続し、カスタマーディスプレー28及びキャッシュドロアー29はプリンターユニット19に接続する。
モニター26は、液晶表示パネルや有機ELパネル等の表示画面を有し、デバイス接続部18から入力される表示信号に基づき各種画面を表示する。デバイス接続部18は、処理装置制御部12の制御に従って、モニター26に表示信号を出力する。
バーコードスキャナー27は、商品、商品の包装或いは読み取り用のシート等のバーコードを読み取り、読取結果をデバイス接続部18に出力する。POS装置10を操作するオペレーターが、販売する商品を登録するときに、バーコードスキャナー27で商品のバーコードを読み取る操作を行う。バーコードスキャナー27は、例えばバーコードスキャナー47と同様に構成できる。デバイス接続部18は、バーコードスキャナー27が出力するPLUデータを取得して、処理装置制御部12に出力する。
プリンター制御部12cは、ブラウザー実行部12aが出力するテキストデータや画像データに基づき、プリンターユニット19を制御して、レシートを印刷する。
ブラウザー実行部12aは、図3(A)に示したブラウザー実行部33の動作を実行する。ブラウザー実行部12aは、予め設定されたアクセス先のデータに従って、サーバー50に対してHTMLファイル63の送信を要求し(ステップS11)、サーバー50が送信するHTMLファイル63をダウンロードして実行し(ステップS12)、ウェブアプリケーションを実行する。
POS装置10を操作するオペレーターが、バーコードスキャナー27を操作して、商取引の対象となる商品のバーコードを読み取ると(ステップS13)、デバイス接続部18が読取結果を取得し(ステップS14)、PLUデータを生成してブラウザー実行部12aに出力する。ブラウザー実行部12aは、PLUデータをサーバー50に送信する(ステップS15)。
ここで、ブラウザー実行部12aは、バーコードスキャナー27が読み取ったPLUデータに対応する商品名、単価、商品カテゴリー等をモニター26に表示する。また、バーコードスキャナー27によるバーコードの読み取り、又は、図示しない入力デバイスの操作により、商品数量、預かり金額等が入力されると、ブラウザー実行部12aは、入力されたデータを取得する。ブラウザー実行部12aは、入力データに基づきウェブアプリケーションの機能で合計金額を算出し、合計金額と釣り銭の金額等をモニター26に表示する。また、ブラウザー実行部12aは、必要に応じてキャッシュドロアー29を開く指示を送信する。
ブラウザー実行部12aが上記ステップS11~S19の動作を実行する間、アプリケーション実行部52は、POS装置30がウェブアプリケーションを実行する場合と同様に、図3(B)の動作を実行する。
このように、POS装置10は、POS装置30と同様、オペレーターの操作に応じてPOSとして会計処理を実行し、POS装置10の会計処理の結果がサーバー側売上データ66に反映される。
図4(A)は、POS装置10とサーバー50、及び、POS装置30とサーバー50とが通信を行ってPOSの機能を実行する場合の動作を示す。タブレット31は、端末通信路N1を通じてサーバー50と通信する。タブレット31は、端末通信路N1でPLUデータに基づく問合せを行い、サーバー50が問合せの結果(価格データ)を送信し、タブレット31が処理結果を送信する。また、処理装置11は、サーバー通信路N2を通じてサーバー50と通信し、PLUデータに基づく問合せを行い、サーバー50が問合せの結果(価格データ)を送信し、処理装置11が処理結果を送信する。サーバー50は、処理装置11及びタブレット31が送信する処理結果に基づき、データベース65のサーバー側売上データ66を更新する。
この場合、タブレット31は、処理通信路N3を通じて処理装置11と通信する。タブレット31は、処理通信路N3でPLUデータに基づく問合せを行い、処理装置11が、サーバー50と同様に動作して、問合せの結果(価格データ)を送信する。また、タブレット31が処理結果を送信すると、処理装置11は、タブレット31が送信する処理結果に基づき、データベースを更新する。
アプリケーション実行部12dは、補助記憶部20及びデータ記憶部23が記憶するデータに基づき、アプリケーション実行部52(図1)と同様の機能を提供する。
補助記憶部20は、POSアプリケーション21、及び、HTMLファイル22を記憶する。POSアプリケーション21は、データ記憶部61が記憶するPOSアプリケーション62の代替として使用可能なアプリケーションである。HTMLファイル22は、データ記憶部61が記憶するHTMLファイル63の代替として使用可能なファイルである。アプリケーション実行部12dは、POSアプリケーション21を実行してウェブアプリケーションを動作させる。
データ記憶部23は、処理装置側売上データ24、及び、処理装置側マスターデータ25を記憶する。処理装置側売上データ24はサーバー側売上データ66と同じ内容のデータを含み、処理装置側マスターデータ25はサーバー側マスターデータ67と同じ内容のデータを含む。
また、アプリケーション実行部12dは、タブレット31が送信するPLUデータを受信して(ステップS23)、受信したPLUデータに基づき処理装置側マスターデータ25を参照する(ステップS24)。アプリケーション実行部12dは、受信したPLUデータに対応する価格データを処理装置側マスターデータ25から抽出して、POS装置30に送信する(ステップS25)。
アプリケーション実行部12dは、POS装置30が送信する処理結果を受信し(ステップS26)、受信した処理結果を処理装置側売上データ24に登録し、処理装置側売上データ24を更新する(ステップS27)。
また、処理装置側マスターデータ25とサーバー側マスターデータ67とは同一のデータでもよいが、一部が異なっていてもよい。アプリケーション実行部52がPLUデータに基づいてサーバー側マスターデータ67を参照して得る価格データと、ブラウザー実行部12aが処理装置側マスターデータ25を参照して得る価格データとが一致すればよい。処理装置側売上データ24とサーバー側売上データ66とは、同じ処理結果に基づく同じデータを含んでいればよく、例えばデータ構造等が異なっていてもよい。
最も単純な例では、POSアプリケーション21とPOSアプリケーション62、及び、HTMLファイル22とHTMLファイル63とが、それぞれ同一である。また、処理装置側売上データ24とサーバー側売上データ66、及び、処理装置側マスターデータ25とサーバー側マスターデータ67とが、それぞれ同一である。
この場合、処理装置11の内部において、ブラウザー実行部12a及びアプリケーション実行部12dが互いにデータを送受信する。このため、サーバー通信路N2が通信可能な状態でなくても、POSとして機能できる。
このため、データ処理システム1は、端末通信路N1及びサーバー通信路N2のうち、通信可能な状態でないと判定された通信路が、通信可能な状態に変化(回復)すると、図4(C)の復旧動作を実行する。この復旧動作では、処理装置11とサーバー50とが通信を行い、処理装置側売上データ24とサーバー側売上データ66を整合させる。これにより、サーバー側売上データ66に、障害回避動作中の処理装置11及びタブレット31の処理結果が登録される。
ブラウザー実行部33は、端末通信路N1の通信状態を検出し(ステップS41)、端末通信条件を満たすか否かを判定する(ステップS42)。ステップS41を実行するタイミングは任意であり、端末通信路N1でサーバー50と通信中に実行してもよいし、会計処理を行う間に実行してもよい。また、サーバー50と通信していない間も設定された時間毎にステップS41を実行してもよい。
トランザクションを実行中である場合(ステップS48;Yes)、ブラウザー実行部33は、実行中のトランザクションが完了するまで待機する(ステップS49)。具体的には処理結果を送信するまで待機する。その後、ブラウザー実行部33は、接続先を処理装置11からサーバー50に切り替え(ステップS50)、処理装置11に対して、接続先をサーバーに切り替えることを通知する(ステップS51)。また、トランザクションを実行中でない場合(ステップS48;No)、ブラウザー実行部33はステップS50に移行する。
処理装置11のブラウザー実行部12aは、サーバー通信路N2の通信状態を検出し(ステップS61)、サーバー通信条件を満たすか否かを判定する(ステップS62)。ステップS61を実行するタイミングは任意であり、サーバー通信路N2でサーバー50と通信中に実行してもよいし、会計処理を行う間に実行してもよい。また、サーバー50と通信していない間も設定された時間毎にステップS61を実行してもよい。
その後、ブラウザー実行部12aは、接続先をサーバー50に切り替え(ステップS71)、タブレット31に対して、接続先をサーバーに切り替えることを通知する(ステップS72)。また、トランザクションを実行中でない場合(ステップS69;No)、ブラウザー実行部12aはステップS71に移行する。
また、処理装置11は、サーバー通信路N2が、与えられたサーバー通信条件を満たさない場合、タブレット31が送信する処理結果を受信してデータ記憶部23に記憶し、データ記憶部23に記憶する処理結果に基づいてデータ記憶部23に記憶する処理装置側マスターデータ25を更新する。このため、処理装置11をサーバー50に接続するサーバー通信路N2が条件を満たさない場合に、タブレット31が送信する処理結果を記憶して処理できる。
また、処理装置11は、サーバー通信路N2の通信状態が、サーバー通信条件を満たさない状態からサーバー通信条件を満たす状態に変化(回復)した場合、データ記憶部23に蓄積した処理結果をサーバー50に送信する。このため、サーバー通信路N2の通信状態が条件を満たす状態に回復した場合に、タブレット31が送信した情報をサーバー50に送信できる。
また、データ処理システム1では、タブレット31が、端末通信路N1が端末通信条件を満たす場合、端末通信路N1を通じてサーバー50に接続し、サーバー側マスターデータ67に基づいて処理を実行し、実行した処理に関する処理結果をサーバー50に送信する。このため、タブレット31がサーバー50のデータに基づいて実行した処理に関する情報を、サーバー50で処理できる。
また、処理装置11及びタブレット31は、POSアプリケーション62、21をウェブブラウザーで実行することにより、処理を行うことができる。
