Database Management

A robust and efficient database management system resolves all your data worries, giving your business the power to lead.

Hookninjas Database Management Systems (Hdbms)

Hookninjas database management system (HDBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose HDBMS is designed to allow the definition, creation, querying, update, and administration of databases.

Hookninjas database management system (HDBMS) is system software for creating and managing databases. The HDBMS provides users and programmers with a systematic way to create, retrieve, update and manage data. HDBMS makes it possible for end users to create, read, update and delete data in a database. The HDBMS essentially serves as an interface between the database and end users or application programs, ensuring that data is consistently organized and remains easily accessible.

The HDBMS manages three important things: 

  • The data
  • The database engine that allows data to be accessed, locked and modified 
  • The database schema, which defines the database’s logical structure. 

These three foundational elements help provide concurrency, security, data integrity and uniform administration procedures. Typical database administration tasks supported by the DBMS include change management, performance monitoring/tuning and backup and recovery. Many database management systems are also responsible for automated rollbacks, restarts and recovery as well as the logging and auditing of activity.

The DBMS is perhaps most useful for providing a centralized view of data that can be accessed by multiple users, from multiple locations, in a controlled manner. HDBMS can limit what data the end user sees, as well as how that end user can view the data, providing many views of a single database schema. End users and software programs are free from having to understand where the data is physically located or on what type of storage media it resides because the HDBMS handles all requests.

The HDBMS can offer both logical and physical data independence. That means it can protect users and applications from needing to know where data is stored or having to be concerned about changes to the physical structure of data (storage and hardware). As long as programs use the application programming interface (API) for the database that is provided by the HDBMS, developers won’t have to modify programs just because changes have been made to the database.

With relational HDBMSs (RHDBMSs), this API is SQL, a standard programming language for defining, protecting and accessing data in a RHDBMS.

Popular types of HDBMS

Popular database models and their management systems include:

  • Relational Hookninjas database management system (RHDMS)  – adaptable to most use cases, but RHDBMS Tier-1 products can be quite expensive.
  • NoSQL HDBMS – well-suited for loosely defined data structures that may evolve over time. 
  • In-memory Hookninjas database management system (IMHDBMS) – provides faster response times and better performance.
  • Columnar Hookninjas database management system (CHDBMS) – well-suited for data warehouses that have a large number of similar data items.
  • Hookninjas Cloud-base  data management system(HCBDMS) – the cloud service provider is responsible for providing and maintaining the HDBMS.

Advantages of a HDBMS

Using a HDBMS to store and manage data comes with advantages, but also overhead. One of the biggest advantages of using a HDBMS is that it lets end users and application programmers access and use the same data while managing data integrity. Data is better protected and maintained when it can be shared using a HDBMS instead of creating new iterations of the same data stored in new files for every new application. The HDBMS provides a central store of data that can be accessed by multiple users in a controlled manner.

Central storage and management of data within the HDBMS provides:

  • Data abstraction and independence
  • Data security
  • A locking mechanism for concurrent access
  • An efficient handler to balance the needs of multiple applications using the same data
  • The ability to swiftly recover from crashes and errors, including restart ability and recoverability
  • Robust data integrity capabilities
  • Logging and auditing of activity
  • Simple access using a standard application programming interface (API)
  • Uniform administration procedures for data

Another advantage of a HDBMS is that it can be used to impose a logical, structured organization on the data. HDBMS delivers economy of scale for processing large amounts of data because it is optimized for such operations.

HDBMS can also provide many views of a single database schema. A view defines what data the user sees and how that user sees the data. The HDBMS provides a level of abstraction between the conceptual schema that defines the logical structure of the database and the physical schema that describes the files, indexes and other physical mechanisms used by the database. When a HDBMS is used, systems can be modified much more easily when business requirements change. New categories of data can be added to the database without disrupting the existing system and applications can be insulated from how data is structured and stored.

Of course, a HDBMS must perform additional work to provide these advantages, thereby bringing with it the overhead. HDBMS will use more memory and CPU than a simple file storage system. And, of course, different types of HDBMS will require different types and levels of system resources.

What are examples of database software?

Some examples of database software are Oracle, FileMaker Pro, Microsoft Access, Microsoft SQL Server, SAP and MySQL. Database software, also called a database management system or DBMS, is used to store, retrieve, add, delete and modify data.

Database software provides an interface for the users and the database. The interactions facilitated by DBMS include data definition and update, retrieval for reports or queries, and administration of data security and recovery. Some applications of DBMS include a computerized system for libraries, flight reservations, company bookkeeping, client profiling and store inventory. More DBMS applications are possible if the database administrators and systems analysts customize the DBMS to meet the needs of the end users.
