Database Management refers to managing data in a database. A Database is the back-end of any software system. It collects all the information used in the software system or application, after which you can effortlessly search, sort and analyze the data. Clients often contact us because their present database system does not perform the way they need it to perform.
We can build a database from the ground up or integrate a database like e.g. MySQL or SQL Server with your software or site. Our up-to-date knowledge in the field of web technology and database management systems allows us to deliver practical, efficient and manageable solutions to our customers.
We have both skilled database developers and administrators. Our database developer works on database technologies, while a database administrator typically focuses more on routine maintenance and support for your existing database setup.
What is Database Management?
Database Management is a process of defining, manipulating, retrieving and managing data in a database. A Database Management System (DBMS) is integrated to automatically manipulate data itself inside a database, including data formats, record & file structures, field names, and validates rules. A database administrator (DBA) is an instructor of a DBMS that commands databases to make necessary changes in loading, modifying and retrieving existing data.
Some Database Management Systems are:
- SQL Server
Types of Databases
Databases are developed according to user requirements. Different kinds of databases serve different purposes and are different in structure & capability. Some of the most used databases are:
In this database, the data is stored in a fixed centralized location, and multiple users can access data at the same time from different locations. People can access data stored in a centralized database but need authentication first to do so. Validation & verification measures are integrated into the system.
Distributed databases are just opposite of centralized database in which consists of data from the shared databases and local computers. Data is distributed to various other sites within the same station. These sites are connected, and communication between these sites is established. We can further categorize Distributed databases into two different categories of homogeneous & heterogeneous databases.
The end-user database is a shared kind of database that collects summaries of information and provides it to end-users. It has nothing to do with transactions or operations which we execute at various levels. It is concerned with the product, which may be a software or an application.
Operational databases manage data in real-time. It is like a data warehouse that stores data in an instant. Operational databases can be either SQL or NoSQL and elements on a functional database can be added and removed within seconds. Real-time information includes payroll records, employee data or customer information and provides real-time operations.
Relational database stores data in a set of tables, which consists of rows and columns. The column in the table has an entry for data for a category and rows contains instance for that data defined for the class. Relational databases use SQL as an application program interface. Relational databases one of the most used database categories because of their structured data storing in rows and columns functionality.
People nowadays use clouds, AKA virtual environments to store data. We categorize Clouds into three categories:
- Hybrid Cloud: A cloud database consisting of the functionality of both public and private clouds.
- Public Cloud: It is an open database where everyone can access database and retrieve data.
- Private Cloud: In a private cloud database only authorized users can access data
Cloud database extends the functionality of almost all other databases as it is well optimized and maintains a virtual environment in which you can pay per acquired storage capacity and bandwidth used or per user basis. These databases have high availability and provide scalability.
These databases consist of relational databases and the use of object-oriented programming languages such as C++, Java. Various items of these databases are created using the OOP language. We store these items in a relational database inside an object-oriented database. Those items can also be stored only in a relational database, but the object-oriented database is more suitable as it is well organized.
Commercial databases are subject-specific databases, which are the paid version of the enormous database created for users who access database information for help. These databases are maintained by upper-level managers and access to these databases is provided only though commercial links. These are large databases, and individuals cannot sustain such colossal information.
Personal database stores data and information on a personal computer. Private databases are small and easy to manage. Access to these databases is limited to a small group of people inside an organization. Database management activities of personal databases are easy to carry out.
Graph Database plays with nodes, edges, and entities. An edge in graph database represents a relationship between objects and these objects can be connected to other entities as well. These databases are used for mining data and analyzing interconnection.
The Survey shows more than 2.5 quin-trillion bytes of data are generated every day. Even in an organization, millions of data is acquired within a single working day. Database developers carry out database management tasks & help harness this data and its power. If you look down from the top of a building, what you will see is data & a lot of data. We organize this data in a database and development of a database that would store different kinds of data like images, videos, photos, texts, cryptographic data and more is called database development.
