什麼是數據庫管理軟件? 

數據庫管理軟件充當最終用戶和數據庫之間的接口。它管理數據,數據庫引擎和數據庫模式,以促進數據組織和數據庫系統的持續運行。 

它使用命令來操作數據庫管理系統。它從數據庫管理員那裡接收命令,然後指示數據庫檢索數據,修改數據或讀取現有數據。 

典型的DBMS模型包括基於雲的數據庫管理系統,例如 AWS數據庫 服務,內存數據庫管理系統(IMDBMS),列式數據庫管理系統(CDBMS)和NoSQL數據庫。

數據庫管理軟件功能 

有許多數據庫管理工具可供選擇。 DBMS的最基本功能是: 

 

  • 數據結構-a well-defined hierarchical structure organizes information into records, objects or tables. This type of database organization ensures easy searching, retrieval, and querying. 
  • 數據庫定制-provides capabilities to create custom elements, in addition to basic records, objects and tables, and meet unique user needs. 
  • 資料檢索-ensures database management systems receive data input from users or integrated applications, storing data in relevant locations. Users can later access the database to retrieve the records to a file, print them, or display them on the screen. 
  • 查詢語言-a universal DBMS allows you to use a query language to perform tasks that help users interact with records in the database, such as collecting, searching, sorting and modifying data. 
  • 多用戶訪問-DBMS provides multiple users with access to information stored in the same data storage area. It should provide security mechanisms to limit access to data to specific users. 
  • 數據的完整性-all information in the database can be accessed by multiple users, but a locking mechanism ensures only one user can modify the same data at the same time. This prevents data corruption. 
  • 元數據-is data that describes the elements (such as records, objects, and related files) that make up the structure of the database.

 

什麼是數據庫管理軟件? 

DBMS系統的關鍵價值包括: 

 

DBMS允許用戶(本地和遠程)以標準化方式輕鬆共享數據。由於數據是經過結構化,管理和最新的,因此DBMS可以使用最新的相關信息來響應即席查詢,並向應用程序或用戶提供查詢集。 

 

當多個用戶訪問數據庫時,數據洩露的威脅變得更加明顯。與非結構化形式的數據存儲相比,數據庫管理軟件可以通過受控的用戶訪問更好地實現數據機密性和安全性準則。 

 

簡化的數據訪問和從數據中提取有價值的見解的工具使操作員能夠做出迅速而明智的決策。幾乎每個行業都使用DBMS應用程序。一些常用的用法: 

  • 銀行業務-customer information, account activity, and payments 
  • 航空公司-flight booking and itinerary information 
  • 電訊-monthly bills and logging of calls and other events 
  • 金融-storing data about financial instruments such like stocks and bonds 
  • 銷售量-storing customer information and history (as in customer relationship management or CRM systems), product data, customer purchases 
  • 製造業-supply chain management, keeping record of manufacturing items in warehouses, tracking inventory 
  • 人力資源-employee data, salaries, deductions, aggregate payroll data 

 

選擇數據庫管理軟件時的主要注意事項 

選擇一個好的數據庫管理系統是業務成功的關鍵。選擇DBMS時,需要考慮以下幾個關鍵因素: 

 

Consider how familiar the system is to employees who need to use it and those who need to manage it. Database users may include marketing professionals, IT departments, database developers, and more. Check applicability from everyone’s point of view-both the end user experience and the administrator or developer experience. 

 

Try to slice and dice data to see how easy it is to visually analyze datasets and view the results of queries. Visualizations provided by the database should be suitable for the task at hand. Consider how users will use the data-for their own use, for presenting to management, for the creation of automated reports, etc.-and ensure the database can generate those visualizations or reports, or integrate with other systems that can generate them. 

 

確保數據庫管理軟件中可用的模塊滿足您的業務需求。考慮以下功能: 

 

  • 數據提取與過濾 
  • 可視化和見解 
  • 預測分析 
  • 數據分割與建模 
  • 數據庫和數據操作的自動化 
  • 與您的組織使用的其他系統集成 

 

DBMS系統通常包含敏感數據。你可以實現 數據保護 通過授權和身份驗證以及數據加密。數據保護方法取決於數據結構和您的安全性要求,在DBMS評估過程中應仔細考慮。 

 

確保系統可以隨著您的數據和業務增長。大多數企業會定期收集和更新大量數據,因此請確保您的數據庫管理系統具有相當高的容量,並且通過與其他數據庫單元進行群集或按需進行彈性伸縮(如按圖所示)來輕鬆地進行擴展。雲數據庫服務。  

Also consider the storage aspect-if running on-premises, what type of data storage equipment do you need, in what quantity, what is the cost and what are the ongoing costs for operating the equipment. 

 

您必須考慮數據更新頻率以及自動化的需求。是實時,每隔幾秒鐘或幾分鐘,還是每小時或每天一次更新數據庫?同樣,請考慮消耗數據的頻率以及用戶所需的新鮮度是多少。為了自動化數據更新並促進與其他系統的集成,您需要了解數據源並確保其特徵與DBMS兼容。還考慮DBMS如何處理數據源結構或架構的更改,或添加新的數據源。 

 

使用Raima的數據庫管理軟件

Raima Database Manager (RDM), is a linkable library that you easily embed within your application to Collect, Store, Manage and Move data in near real-time – requiring zero ongoing administration.  RDM is perfectly designed to be bundled inside applications that run on small embedded IoT or IIoT devices out on the edge or in the fog, e.g. collecting all information gathered from a network of sensors and actuators, then securely delivery that data up to enterprise level hardware systems in the Cloud. 

RDM comes fully compiled and packaged for software developers with options to meet a variety of data management architectural designs by providing a choice of data models and access methods to solve the most stringent performance requirements.  RDM is a solid time-tested ACID compliant database technology that employs a number of advanced options to meet today’s more complex data management challenges such as building highly-available database systems, moving data from small low-powered embedded devices up into larger enterprise systems, managing information purely in-memory, database partitioning support to facilitate data distribution and scalability, and interfaces allowing access to the data from external sources.
