With the Shaanxi Expressway networking toll, toll extension business is now weighing charges for storage charges database security and backup of business data has become more prominent. After two years of operation, more and more awareness of the operating units to database stability issues is a problem not to be ignored. Simple examples such as: failure of the servers and databases, general maintenance and management staff, in many cases, cannot be independent and quick recovery, had an impact on production. So we need a proper data backup solutions. Database is the core of the whole system, database security should pay more attention. Therefore, the formulation of appropriate database backup strategy, is to maintain database security norms as well as the guidelines, to backup the data it needs from the technical, as well as administratively regulated. In data security, data security strategy is to maintain the integrity, confidentiality and availability of information. Therefore, database security policy will focus on these three points, including physical security, access control, data backup and emergency response. Here, in the toll collection system in the province uses the SQL Server database as an example to illustrate the idea of developing its security policy. 1 research background of construction of networked Expressway toll collection system reduced the number of drivers vehicles in the road network and improve road capacity, reducing environmental pollution due to parking, enhance the economic benefits of Highway and social image. Shaanxi Provincial Expressway networking toll began in May 2004, as of now there are more than 200 data server, as more sections of grid-connected charges, charges data as the core of the whole system, it is necessary to establish a set of data security and reliable solution. 2 purpose this time through the analysis of network data in server health, Shaanxi Provincial Expressway networking toll system based on data, statistical methods of data storage, data research, original charge as possible security, integrity and privacy of data. For the opening section after incorporation fees provide a reliable set of data security policies. 3 database security situation in the province Shaanxi Provincial Expressway networking toll system overview 3.1 database-tier systems, management systems, branch-level management system, the provincial network centre split and transfer system, four-level system. Each system has its own separate data server is used to store their collection of premium business data, provide the basis for statistical analysis. 1, stand-level server storage fees collected from toll lanes flowing data and pass on this site blessing Kaku, cartridge information within this site, card box allocation, cartridge combination of information and frequency information. 2, the main storage server server charges collected water from under the jurisdiction of the station data and the pass of blessing Kaku, the internal cartridge information, reallocation of the cartridge and cartridge combination, personnel information, flight information, charges the actual payment data entry work. 3, Center-class server storage server charges collected water from under the jurisdiction of the station dataWater data integrity can be up and running. So when a database server fails, you do not need to pass data to recover, simply through the collection procedure for charging water data collection to complete the fast recovery of server failures. 4.4 analysis summary summary analysis, lane because it is not a complete station level data, so there is no need for dedicated backup. Stand-level server data because it is at the front of the charge as a whole, its fault directly affects the exercise normally, you need a complete offsite backup solution. Management, and data center server, due to its operations without manual data entry, so just use common artificial scheduled backups can be. 5 solutions in order to ensure that when the server after a hardware failover, backup data without changes or only minor changes can be quick and easy troubleshooting of server data recovery, you專業教學資源庫主要建設內容建議一、專業資源庫的功能：1.學生：課程學習、學習評價、虛擬實訓、在線測試、培訓考證、咨詢交流。2.教師：專業建設、教學參考、技術進修、溝通交流3.社會學習者：學習、交流、實踐、考證、求職。 4.企業：企業宣傳、員工培訓、技術交流、經驗分享、人才招聘。二、專業資源庫的主要內容（一）專業資源：目的是準確定位專業人才培養目標和主要就業崗位，對課程體系和課程設置提供建議。包含專業就業崗位、職業崗位能力分析、人才培養方案庫、人才培養規格、課程體系、人才培養模式、實驗實訓基地建設等。子資源名稱子資源分類專業概況庫專業概況專業建設依據分析庫數據調查（行業發展及人才市場數據調查報告）政府規劃與政策數據分析報告（國際、人才需求、職業能力及行業前景分析報告）培養方案庫人才培養模式報告人才培養方案課程標準庫專業開設條件庫要求和條件保障（師資隊伍結構、實踐教學條件和環境及過程質量保證）人才培養質量及評價體系（包括證書及社會評價）專業成果共享庫(市、省、國家)品牌/特色專業成果示范/骨干院校建設成果省、國家精品課程成果（二）課程資源：目的是建成集自主學習與教學功能為一體的個性化學習與教學平臺，具備自主學習、在線交流的功能。對資源進行統一整合，從專業方向、課程、層次等角度進行組織，方便用戶快速搜索，在線瀏覽和下載。主要內容是主干課程的課程標準、學習指南、整體設計、單元設計（教案）、教學視頻、考核方案、案例庫、電子教材、電子課件、習題試題庫等內容。子資源名稱子資源分類具體建設內容主干課程課程標準課程標準學習指南學習引導，學習方法、學習路徑整體設計整體設計、內容選取與組織、教學安排等單元設計學習情境設計教學課件全部學習情境的電子課件教學視頻整體設計錄像和學習情境教學視頻習題、試題庫配套習題庫、試題庫項目庫包括課程綜合案例和學生作品庫考核方案考核評價方案（三）行業資源：收集和整理行業資源，集中展示專業領域的國內外著名企業、領軍人物，滿足企業品牌宣傳、產品推廣、人才招聘等多方面的需求，企業可以獲悉前沿技術動態，提升產品市場競爭力和企業創新能力。主要內容包括行業概況、行業產品、行業崗位、技術前沿、政策法規、標準規范、企業風采、領軍人物、人才供求、行業新聞等建設子項目。子資源名稱子資源分類行業概況行業、行業協會行業產品系統軟件行業崗位工作崗位技術前沿技術前沿政策法規政策法規標準規范標準規范企業風采企業風采領軍人物領軍人物人才供求企業招聘信息行業新聞行業新聞（四）素材資源：建成便于用戶集成創新、直接使用和消化吸收的滿足基本需求和個性需求的素材資源。主要包括教學素材（教學文檔模板、習題庫、試題庫、課程項目案例庫、學生作品庫）和課程學習所需的各類素材。子資源名稱子資源分類具體建設內容教學素材教學文檔模板課程標準、整體教學設計、單元設計、授課計劃、教案與備課筆記等。習題庫、試題庫各門課程習題、各門課程完整試題等。課程項目案例庫學生作品庫學生作品簡介、設計過程、實施結果等。（500）課程素材各類素材（五）培訓資源：根據行業、職業標準，建成涵蓋師資培訓、企業證書培訓、行業證書培訓、項目開發與管理、前沿技術等在內的各種培訓包，形成在線培訓資源。各類培訓包中包括培訓指南、培訓內容、培訓資源、培訓證書、合作單位信息等。need to select the real-time synchronization method of the programme. Typically backup system comes with backup solutions should be preferred. If the system comes with a backup plan if it cannot meet the requirements, software development methods is needed. Or third-party software systems are selected for backup. Because third-party backup software is usually priced very high, charging units require high price, so for only the first two methods are studied below. 5.1 use MS SQL2000 synchronized backups of SQL 2000 database in three ways, namely snapshot replication, transactional replication and merge replication. By comparison, excluding the first two programmes, select synchronization transactional replication and database Nothwind database, for example, for testing. The three parts of the main considerations in the synchronization of the data, can be thought of as three hosts. The Publisher, Distributor, and Subscriber; can be understood from the literal meaning, function is actually implemented to keep subscribers through the Distributor data timely and consistent data at the Publisher. 1, about snapshot replication to copy data changes infrequently, or are not required to keep the data current values (low latency), snapshot data is one of the best methods of data replication. When synchronization occurs, complete snapshot is generated and sent to the Subscriber. Because snapshot replication bulk copies released (items collection) a complete copy, it will publish all writes made to the snapshot folder. Project is to specify that you want to copy tables, data partitioning, or database objects. Projects can be a full table and certain columns (using a vertical filter), certain rows (using a horizontal filter), a stored procedure or view definition, the stored procedure execution, view, indexed, view, or user-defined function. Snapshot replication does not maintain data the fastest real-time updates, and the bulk copy released (items collection) a full copy of the mechanism will generate a lot of network traffic. Only small volumes of replication used, data is static and does not need to be updated in real time database. So do not use snapshot replication the synchronization modeData table, add a new data field MSrepl_tran_version, publishing software depending on whether the contents of this field changes to determine whether you need to publish the data. And SQL 2000 data is modified judging is managed by the kernel, not for external programming. Such as modify the structure of the original data table, a direct result of running lanes and management software that doesnt work. Due to the above test results to prove that this scenario is not suitable as a backup method for networking toll system in Shaanxi Province. 5.2 using specially developed backup software after the above tests, through the systems subscriptions, publish method in Shanxi province under the networking software sync backup, demand cannot be met, backup software so I decided to use for the development of synchronization, synchronize backups. As a result of independent development, it has a high degree of flexibility in backup. Easier for seamless integration with existing systems. Backup sof
