A Necessary Condition For The Storage Of Information

Data is ever increasing. We need a system to represent, store and manipulate complex information, detect correlations and patterns, construct data models etc. Furthermore, being independently maintained, data can change in time or even change its base structure, making it difficult for modelling systems to accommodate these changes. Current representation and storage systems are not very flexible in dealing with structural changes and also they are not powered with the ability of performing complex data manipulations of the sort mentioned above.

iv) Database : Database are proposed to record the complete state of some related sets of

The data structure represents the logical relationships between data elements. In addition the data also determines the organizational structure, access methods, and alternative processing assosiativitas level for information.

Storing information is the process where information is deposited or stored in a storehouse (cabinets, HDD, memory stick, etc) and retrieving information is the process of obtaining the stored information resources relevant to the needs.

In all information systems, data resources must be organized and structured in some logical manner, so that they can be:

In the field of computer information, there is a vast amount of information that is used for operations. This information must be stored somewhere in order to be used in the future, and for programs to use

Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.

The ability to store information has always been important for our survival. In the beginning, information used to be shared by word of mouth. Then, with the invention of writing, data slowly started to be stored in books kept in libraries, sorted in specific order that made them easily accessible. Finally, the invention of the computers led to the evolution of databases.

The relational model, which uses predefined tabular relations to store data, has remained the preeminent model for data storage since it was first implemented in the early 1980s. However, due to the proliferation of the Internet, today data flows in and out of organizations quickly, and most of this data is in a semi-structured state that is designed for communication over http. It is difficult to fit this complex data into a flat two dimensional array. For that reason, it is imperative that companies have the ability to store data in a semi-structured format compatible with modern network communications as well as various platforms and devices. The market has realized this and responded with document stores that support formats,

Information: Data that have been organized so that they have meaning and value to the recipient. (CH01)Slide#9

knowledge content represents the individual info and management objects that represent some larger assortment of knowledge reworked by the computer code. as AN example, the data object, standing declare could also be a composite of form of necessary things of data: the aircraft’s name, the aircraft’s model, ground run, no of hour flying then forth. Therefore, the content of standing declares is made public by the attributes that unit of measurement needed to form it. Similarly, the content of a

Probably the first report generation “language” was developed in 1959 for the IBM 7090 and known as “9PAC”. At the time, storing and accessing structured data on computers was still in its infancy, and some concepts from 9PAC formed key parts of the development of early relational databases.

The stored program concept or stored program architecture, which is also known as von Neumann architecture, is such a big deal because it is the milestone in general purpose electronic computer development (Sharma, 2015). To elaborate, the stored program concept provides two beneficial functions that modified the design of computers. First, computers would have the ability to signal and store programs and data in the same ROM or RAM (Sharma, 2015). By viewing programs as data and vice versa, the stored program concept simplifies the hardware and the software of computers. This would suggest that programs are represented by machine code, indicating that programs are understood by the computer and can then be stored in the computer’s memory. Second, computers would be able to fetch, decode and execute a program written in machine code sequentially using the central processing unit to perform arithmetic and logical operations; ROM to boot up permanently stored programs and data; or RAM to temporarily store programs and data executed by the central processing unit, and; input-output interfaces that establish a communication between input and output devices, allowing the central processing unit to send and receive information from the output device (Sharma, 2015). This suggests that the human does not have to execute a program from within the computer. For instance, the concept of Hollerith’s pre-formatted punch cards for computers, such as the “IBM CALCULATOR INSTRUCTION CARD”

Storage requirements: - storage requirements is first and most important in designing. A great deal of thought go into examining the storage requirements. The physical size of the database, you have to consider the exchange development rate and data distribution requirements. There are some topic which are assessing current storage capacity:-

Local data structures: It verifies that during program execution integrity of data is executing properly.
