步骤S1，接收用户的访问请求。
本实施例中，数据访问系统接收用户发出的数据访问请求，例如，接收用户通过手机、平板电脑、自助终端设备等终端发送的数据访问请求，如接收用户在手机、平板电脑、自助终端设备等终端中预先安装的客户端上发送来的数据访问请求，或接收用户在手机、平板电脑、自助终端设备等终端中的浏览器系统上发送来的数据访问请求。
步骤S2，检测预先在内存中设定的内存缓存区及物理内存区的负载情况，并根据检测的负载情况，按照预设规则确定所述访问请求对应的数据源，所述数据源为所述内存缓存区及所述物理内存区中的一个；其中，所述内存缓存区及所述物理内存区中均存储有预设基础数据。
本实施例中，预先在内存中设定内存缓存区也即内存高速缓冲区，可预先通过程序设置一块内存区域，用于缓存一些需要用到的数据，例如，从内存里面开辟一块地址空间或堆栈来做缓冲。物理内存区即内存条上提供的临时数据存储空间。
具体地，在预设应用程序如用户使用的各种办公类应用程序启动时，将预设基础数据加载至预先设置的内存缓存区及物理内存区中。该预设基础数据为不频繁变更的基础应用数据，如可供多种办公类应用程序使用的基础数据，例如，该预设基础数据包括但不限于公司组织、架构、岗位信息、用户信息、权限组数据等等。用户在进行数据 访问请求时，一般会频繁调用该预设基础数据。本实施例中，可预先将预设基础数据预先存储至物理内存区中，在预设应用程序启动时，再将预设基础数据加载至预先设置的内存缓存区中；在另一种可选的实施方式中，也可在预设应用程序启动时，将预设基础数据分别加载至预先设置的内存缓存区及物理内存区中，在此不做限定。
此外，在预设应用程序运行时，若所述预设基础数据有更新，如公司组织、架构、岗位信息、用户信息、权限组数据等基础数据发生变更，则同步更新已加载至预先设置的内存缓存区及物理内存区中的对应预设基础数据。以保证存储在预先设置的内存缓存区及物理内存区中的预设基础数据完全一致，且同步更新。这样，后续用户的数据访问请求无论是从预先设置的内存缓存区或物理内存区中调取数据，均能调取到最新正确无误的数据，避免出错。
在收到用户的数据访问请求后，实时检测预先设置的内存缓存区及物理内存区的当前负载情况，如分别统计内存缓存区及物理内存区当前处理的总请求数量，并根据检测的内存缓存区及物理内存区的当前负载情况，按照预设规则确定所述访问请求对应的数据源，其中，所述数据源为所述内存缓存区及所述物理内存区中的一个。例如，在一种可选的实施方式中，若所述内存缓存区当前处理的总请求数量比所述物理内存区当前处理的总请求数量少，即所述内存缓存区的负载较小，则确定所述内存缓存区为所述访问请求对应的数据源；若所述内存缓存区当前处理的总请求数量比所述物理内存区当前处理的总请求数量多，即所述物理内存区当前较空闲，则确定所述物理内存区为所述访问请求对应的数据源。这样，能根据所述内存缓存区及物理内存区的负载情况决策调用当前用户的访问请求所对应的数据源，使 用户在进行高速频繁地数据交互访问时，均能从当前负载较小的数据源中调取数据，使数据访问更高效、稳定。
在另一种可选的实施方式中，还可让当前用户的访问请求优先访问所述内存缓存区，只有在所述内存缓存区当前处理的请求数量超过预设阈值时，才使当前用户的访问请求从所述物理内存区中调取数据。由于内存缓存区的数据读取速度要远快于物理内存区的数据读取速度，因此，让用户的访问请求优先访问所述内存缓存区能极大地提高用户在进行高速频繁地数据交互访问时的数据访问速度及效率。本实施例中，通过在内存中设定内存缓存区，当需要使用一些存储在磁盘或物理内存区中的数据时，可以先判断需要使用的数据是否在设定的内存缓存区中，再进行是否要去磁盘或物理内存区中读取数据的逻辑判断，这样一来，减少了运算判断的次数，使处理器读取数据的速度大大加快。
在又一种可选的实施方式中，还可检测所述内存缓存区及物理内存区是否发生异常，若检测出所述内存缓存区及所述物理内存区中的其中一个发生异常，则将所述内存缓存区及所述物理内存区中未发生异常的作为当前用户访问请求对应的数据源，以保证用户的访问请求能一直有效地实时获取到数据，使数据访问更加稳定。
步骤S3，响应所述访问请求，根据当前用户的访问请求从确定出的数据源内存缓存区或物理内存区中调取所述访问请求所需的数据，实现数据交互访问。
与现有技术相比，本实施例通过预先设置内存缓存区及物理内存区，并将用户访问时所需的基础数据分别存储至内存缓存区及物理内 存区中，在接收到用户的访问请求后，可根据负载情况选择内存缓存区或物理内存区来响应用户的访问请求。由于可根据负载情况来从内存缓存区或物理内存区中调取数据响应请求，在进行高速频繁地数据交互访问时，可根据负载规则灵活选择内存缓存区或物理内存区来响应高速频繁地数据访问请求，从而提高数据访问效率。
如图2所示，图2为本申请数据访问系统10一实施例的应用示意图；在上述实施例的基础上，本实施例中预先设置两个存储区：内存缓存区、物理内存区，在应用程序启动时，将该应用程序要用到的基础数据和不频繁变更的数据(例如公司的组织、架构、岗位信息、用户信息、权限组等数据)加载到内存缓存区中，物理内存区中本身即存储有该应用程序的基础数据和不频繁变更的数据。在该应用程序运行时，若基础数据和不频繁变更的数据(例如公司的组织、架构、岗位信息、用户信息、权限组等数据)遇到变更，即物理内存区在运行时基础数据和不频繁变更的数据有更新，则会同步更新已加载到内存缓存区中的数据，以保证存储在内存缓存区及物理内存区中的基础数据和不频繁变更的数据完全一致，且同步更新。这样，客户的访问请求无论是从内存缓存区或物理内存区中调取数据，均能调取到最新正确无误的数据，避免出错。
在客户访问请求数据时(如在启动的应用程序上进行数据操作)，智能请求均衡器来确定当前客户的访问请求对应的数据源。具体地，智能请求均衡器实时检测当前内存缓存区及物理内存区的负载情况，如果内存缓存区目前处理的请求较少即内存缓存区的负载较小，则确定当前客户的访问请求对应的数据源为内存缓存区，即当前客户的访 问请求优先使用内存缓存区中缓存的数据；如果内存缓存区目前处理的请求较多，物理内存区目前的请求处理较空闲，则确定当前客户的访问请求对应的数据源为物理内存区，即当前客户的访问请求优先使用物理内存区中的数据。这样，能根据数据源的负载情况决策调用对应的存储区(内存缓存区/物理内存区)，使得客户在系统中进行高速频繁地数据交互访问时，均能从当前负载较小的数据源中调取数据，使访问更高效、稳定。
如图3所示，图3为本申请数据访问方法一实施例的流程示意图，该数据访问方法包括以下步骤：
步骤S10，接收用户的访问请求。
本实施例中，数据访问系统接收用户发出的数据访问请求，例如，接收用户通过手机、平板电脑、自助终端设备等终端发送的数据访问请求，如接收用户在手机、平板电脑、自助终端设备等终端中预先安装的客户端上发送来的数据访问请求，或接收用户在手机、平板电脑、自助终端设备等终端中的浏览器系统上发送来的数据访问请求。
步骤S20，检测预先在内存中设定的内存缓存区及物理内存区的负载情况，并根据检测的负载情况，按照预设规则确定所述访问请求对应的数据源，所述数据源为所述内存缓存区及所述物理内存区中的一个；其中，所述内存缓存区及所述物理内存区中均存储有预设基础数据。
本实施例中，预先在内存中设定内存缓存区也即内存高速缓冲区，可预先通过程序设置一块内存区域，用于缓存一些需要用到的数据，例如，从内存里面开辟一块地址空间或堆栈来做缓冲。物理内存 区即内存条上提供的临时数据存储空间。

此外，在预设应用程序运行时，若所述预设基础数据有更新，如公司组织、架构、岗位信息、用户信息、权限组数据等基础数据发生变更，则同步更新已加载至预先设置的内存缓存区及物理内存区中的对应预设基础数据。以保证存储在预先设置的内存缓存区及物理内存区中的预设基础数据完全一致，且同步更新。这样，后续用户的数据访问请求无论是从预先设置的内存缓存区或物理内存区中调取数据，均能调取到最新正确无误的数据，避免出错。

在另一种可选的实施方式中，还可让当前用户的访问请求优先访问所述内存缓存区，只有在所述内存缓存区当前处理的请求数量超过预设阈值时，才使当前用户的访问请求从所述物理内存区中调取数据。由于内存缓存区的数据读取速度要远快于物理内存区的数据读取速度，因此，让用户的访问请求优先访问所述内存缓存区能极大地提高用户在进行高速频繁地数据交互访问时的数据访问速度及效率。本实施例中，通过在内存中设定内存缓存区，当需要使用一些存储在磁盘或物理内存区中的数据时，可以先判断需要使用的数据是否在设定的内存缓存区中，再进行是否要去磁盘或物理内存区中读取数据的逻辑判断，这样一来，减少了运算判断的次数，使处理器读取数据的速度大大加快。

步骤S30，响应所述访问请求，根据当前用户的访问请求从确定出的数据源内存缓存区或物理内存区中调取所述访问请求所需的数据，实现数据交互访问。
与现有技术相比，本实施例通过预先设置内存缓存区及物理内存区，并将用户访问时所需的基础数据分别存储至内存缓存区及物理内存区中，在接收到用户的访问请求后，可根据负载情况选择内存缓存区或物理内存区来响应用户的访问请求。由于可根据负载情况来从内存缓存区或物理内存区中调取数据响应请求，在进行高速频繁地数据交互访问时，可根据负载规则灵活选择内存缓存区或物理内存区来响应高速频繁地数据访问请求，从而提高数据访问效率。
如图2所示，在上述实施例的基础上，本实施例中预先设置两个存储区：内存缓存区、物理内存区，在应用程序启动时，将该应用程序要用到的基础数据和不频繁变更的数据(例如公司的组织、架构、岗位信息、用户信息、权限组等数据)加载到内存缓存区中，物理内存区中本身即存储有该应用程序的基础数据和不频繁变更的数据。在该应用程序运行时，若基础数据和不频繁变更的数据(例如公司的组织、架构、岗位信息、用户信息、权限组等数据)遇到变更，即物理内存区在运行时基础数据和不频繁变更的数据有更新，则会同步更新已加载到内存缓存区中的数据，以保证存储在内存缓存区及物理内存区中的基础数据和不频繁变更的数据完全一致，且同步更新。这样，客户的访问请求无论是从内存缓存区或物理内存区中调取数据，均能调取到最新正确无误的数据，避免出错。
