THE ADVANTAGES OF USING DATABASES WITHIN BUSINESSES There are significant advantages to using databases in a business, especially in large companies. The main benefit of databases is that they save time. With the use of a simple queries, millions of records can be searches in a matter of seconds to give the information needed. Think about how long it would take to go through a million paper records held in files. Another great benefit is that the databases can be accessed by multiple users

1 Introduction Database is any collection of data or information, that is specially organized for rapid search and retrieval by a computer. Databases are structured to facilitate the storage, retrieval, modification, and deletion of data in conjunction with various data-processing operations. A database consists of a file or a set of files. The information in these files may be broken down into records, each of which consists of one or more fields. Fields are the basic units of data storage

importance of relational databases to organizations these days. They are a great tool for controlling, analyzing, recording, storing and monitoring processes and transactions throughout all functional aspects of the organization. While the benefits provided by relational databases are instrumental to the overall operation of an organization, traditional databases still have their limitations. This is where SAP HANA comes in. SAP HANA is probably best described as new form of database that operates as

NoSQL was created in the response to relational databases not being able to handle the scale and changing challenges of modern applications, they also cannot take advantage of the cheap, easy storage abilities and also the processing power accessible now. NoSQL includes a variety of different technologies that were developed in response to the surge of data stored by users, objects and products. They were also developed to contend with the rising frequency that the data is accessed and the performance

Application Software includes programs that do real work for user. Example: Payroll systems, Inventory Control, Manage student database, Word Processor, Spreadsheet and Database Management System etc. Application software consists of the programs for performing tasks particular to the machine's utilization. Examples of application software include spreadsheets, database systems, desktop publishing systems, program development software, and games." Application software is generally what we think of

What is a Relational Database “A relational database is a collection of data items organized as a set of formally-described tables from which data can be accessed or reassembled in many different ways without having to reorganize the database tables. It was invented by E.F. Codd in 1970.” (TechTarget, 2006) A simpler definition of a relational database is a self-describing group of related tables. There are three ways to modify a table. We can insert a record, delete one, or update a record

Database theory Why relationships are important in a database. Relationships on a database establish a connection between two associated and logically related tables, that each have similar data. An example may be a table that contains names of certain students, and another table that contains the student's ID, the code of library books, and the dates on which each specific student checked out that particular library book. Without association of relationship on the relational database, the two

Choosing A Database Everyday the world progressively moves towards a digital future, and the use of physical data storage, such as files in filing cabinets, are becoming obsolete. Most companies store their information into databases to easily manage and share their data within the organization. A database management system (DBMS) is needed to to create, use and maintain databases for the efficient storage and retrieval of data. Why Choose a Database? Before one can begin to choose a database, it is

Relational Database Systems The idea of relational database was first introduced by E.F.Codd at IBM in 1970. It is a kind of computer database in which data is stored in Relations and is represented in the form of tables with rows and columns. Databases can vary in sizes, ranging from very small and simple to very large and complex ones. Database users can access the data practically in an unlimited number of ways. Relational databases help in finding the information in a quick and efficient manner
