Abstract
The rapid change has helped people have access to more information. Big data and information system have helped the technology grow. people are saving more time and have access to more things with more convenience. Technology has helped people in all section of life, it made life easier and more convenient in all section, whether medical, social or technological life. There are so many ways which helped technology grow, but the most important way that took technology to next level is Big Data. A solid information system is essential to obtain relevant data for the decision-making process. The more accurate and relevant the information is, the greater the probability of success is to the people.

Big data
Alexandre Borba Salvador, Ana Akemi Ikeda explain in the article, big data usage in marketing information system. Big data is a term used for information which is processed by processing equipment. the three aspects which helped big data are value, speed and variety, these three characteristics are creating new skills to improve the ability to handle information. the authors further added that “The Internet and the use of social media have transferred the power of creating content to users, greatly in- creasing the generation of information on the Internet. However, this represents a small part of the generated in- formation. Automated sensors, such as RFID (radio-frequency identification), multiplied the volume of collected data, and the volume of stored data in the world is expected to jump from 800,000 petabytes (PB) in 2000 to 35 zettabytes (ZB) in 2020.” According to IBM, Twitter would generate by itself over 7 terabytes (TB) of data a day, while some companies would generate terabytes of data in an hour, due to its sensors and controls. With the growth of sensors and technologies that encourage social collaboration through portable devices, such as smart-phones, the data became more complex, due to its volume and different origins and formats, such as files originating from automatic control, pictures, books, reviews in communities, purchase data, electronic messages and browsing data.” The authors explain that data is expending, and big data is one of the hottest topics in the market these days. they further point out that organization are working to create terabytes of data to control its sensors. I agree the expansion of big data will make the data more multifaceted, and portable devices such as mobile phones will collaborate the technology.

How data helped information system improve?
Information system, an integrated set of components for collecting, storing, and processing data and for providing information, knowledge, and digital products. Business firms and other organizations rely on information systems to carry out and manage their operations, interact with their customers and suppliers. In another word, information system is defined as the software that helps organize and analyze data. So, the purpose of an information system is to turn raw data into useful information that can be used for decision making in an organization. The best way for a management team to analyze data is to use the information system to develop strategic plans and make the best choices when it comes to the next business steps of the company.

How data helps information system improve
Data is important factor in developing and maintaining information systems. there are several types of data in information system management, such as: data requirement, data standards is the fundamental of increasing use of electronic data and it will be growing and operate the requirement of data communication. data sources include Explanations, estimation, judgments, and opinions. data integrity is essential factor to the success of an information system in addition provide accurate information and trust in the system. data strong and retrieval the reliability of the system that can be protected from changes in the construction, in addition its easier to add value to the data by analyze them.

Changing laws and regulation affect security posture information system
Security posture of information system is ranked as key concern for an organization. Research in the field has shown that sensitive personal information is now protected by regulatory requirements that have translated into significant new compliance oversight responsibility for information technology managers who have a legal mandate to ensure that individual employee are adequately prepared and motivated to observe policies and procedures designed to ensure compliance. According Joe Stanganelli,the author compliance and data privacy regs to IT security pros should worry about. “Regulatory compliance and data privacy issues have long been an IT security nightmare – and the EU’s General Data Protection Regulation (GDPR), set to take effect May 25, 2018, is returning IT compliance issues to the forefront of corporate concerns. it can be difficult for even small enterprises to keep up with information security and data privacy compliance. The challenge becomes even greater for large enterprises – particularly when employees (or even entire departments) go rogue with Shadow IT implementations. This is where compliance software can come in handy for keeping track of, maintaining, and enforcing IT-security and data-privacy policies.” The author points out to important points that security compliance is important in information system. I agree with the author, change in laws and regulation will defiantly affect the information system or an organization, the organizations need to to be prepared for any changes, they must have teams to assess laws and regulation all the time to comply with them on regular basis. The author further added that,” Compliance, which is only a point in time, is directly impacted by the ever changing and always evolving rules and regulations which makes it quite challenging for organizations to maintain a sound compliance posture. The continuous expansion and extension of our production environments also adds to the compliance challenges we all face today.” I agree with author Security posture is directly affected by changing laws and regulations, it is also hard for organization to maintain on daily basis, it can affect the products on an organization as well.
