Brief Introduction to Databases.

Put simply, a database is a collection of data stored and accessed electronically. In the modern IT world, Databases are more than just Data storage structures. The Data is organized in a manner that it is easily accessible by computer applications and this is ensured during the design of the Database.

The Databases we have today come in different Models. These models determine the logical structure of the database and fundamentally determine the organization, storage, and manipulation of data in the database. Some of the most popular database models we have today include:

  1. Hierarchical database model

Developed by IBM in the 1960s and essentially the oldest form of database models, the hierarchical database tends to have a tree-like structure where data are stored as records connected to one another through links.

  1. Relational Model

Developed by Codd in 1970, the relational model revolutionized the database field and largely supplanted its predecessors; the hierarchical and network models. It is built on a simple concept of a database being a collection of one or more relations. Its simplicity and elegance in data representation have made this the most popular database model today. With our database homework help service, our developers can build you simple, well structured, efficient and safe relational databases.

  1. Entity-Relationship Model

The ER model allows data involved in real-world enterprises to be described in terms of objects and their relationships, and it is widely used in the development of initial database designs. In this context, an entity is an object in the real world that is distinguishable from other objects while a relationship is an association among two or more entities. At ProgrammingAssignmentHelp.net, we have a proven expertise in dealing with ER database models and our database assignment help service is the key to all your ER database model homework.

  1. Object database model

In this model, information is represented as in form of objects as used in Object-Oriented Programming. We at ProgrammingAssignmentHelp.net have vast knowledge and experience working with ODBMS and any trouble you may be facing with these databases can be handled effectively by our experts.

Database Management Systems (DBMS)

In the 21st century, the success of any organization depends on its ability to acquire accurate and timely data about its operations, to manage this data effectively and use it to analyze and guide its activities. With the growth of data storage and transfer over computer networks, it is essential to ensure effective management of the data in various organization databases for the organizational growth and security. The talk of databases, however, never goes without a mention of database management systems and thus comes the question, what is a DBMS??

Put simply, a DBMS is software designed to assist in maintaining and utilizing large collections of data. Through such software, data can be inserted, manipulated and retrieved from a database hence such software are very important.

Access to modern Databases is provided by use of Database Management Systems (DBMS) which basically are computer software that allows interaction and manipulation of Data in the Database by users. A good DBMS should have the following characteristics:

  • Real-world modeling – The design and architecture of an efficient modern-day DBMS should model real-world objects and entities. This makes it easy for users to store and retrieve data from the Database.
  • Less Redundancy – Most DBMS we have today follow the rules of Normalization which minimizes data redundancy by splitting relations when attributes are detected to have redundant values. Normalization is the mathematical and scientific process used to rid redundancy in Databases.
  • Consistency – Consistency is an important database feature which requires that any transaction made in the database should conform to the database own rules. This is a very important attribute for any DBMS because data inconsistency means that the data retrieved from the database won’t be meaningful to the user.
  • Concurrency and efficiency – A good DBMS should allow multi-user access. However, some restrictions may be added to what information certain level of users can access. It also should ensure efficiency in providing the requested data with accuracy.
  • High-level security – Some of the information stored on a given Database may be very sensitive e.g the Database of a commercial website where users add financial information like Credit card information. Such Databases require a high level of encryption and security to prevent such important information from being accessed by the wrong audience. A good DBMS should offer strict constraints to such type of data and ensure secure entry, manipulation, and retrieval.
  • Ease of scalability – The goal of any organization is to grow over time and therefore a good DBMS should be flexible and easily scalable.

Before the introduction of DBMS, data was mainly stored as a collection of operating system files. This traditional method had many flaws and for this reason, DBMS have come to be greatly appreciated. Some of the advantages of DBMS over file systems include:

  • Data independence
  • Efficient data access
  • Data integrity and security
  • Data administration
  • Concurrent access and crash recovery
  • Reduced application development time.

At ProgrammingAssignmentHelp.net, we apply the best knowledge available to solving your database assignments. We have great experience in the design of databases as well and therefore we are qualified for any kind of issue you may throw at us; whether small database assignments quiz or huge database design project.

Some of the basic steps we undertake in getting you a definitive database assignment help service include:

  1. Getting to understand the need for the database and the environment of its application
  2. Determining the type of data to be fed into the database (As per the assignment requirements)
  3. Determining the required database model to be applied in the design of the database.
  4. Designing the database and solving your assignment.

As easy as the steps may seem, there’s a great deal of knowledge application underlying these steps. You also have to be well equipped with the syntax of the required database language (maybe SQL, OQL, Xqueryetc). As a student, you may not be packed up with all this information and that is why we offer you a cutting-edge service that will get you the best grade even on the toughest of database assignments.
