The 4 V’s of Big Data


In today’s world, Big Data refers to both structured and unstructured volume of data that inundates a business on a daily basis. Over the last decade, companies have built data warehouses and business intelligence systems to secure the data. Many global manufacturers produce huge quantities of data that needs to be analysed for business requirements. An inefficiency to manage this data may hinder the company’s decision-making and eventually reduce efficiency and lead to compliance issues.

With a big data analytics platform and considering 4V’s, manufacturers can achieve producing reports that help in making decisions. Let us see the 4V’s described by the industry analysts as the major elements of big data.


Big data always has a large volume of data. This is due to the building up of a volume of data from unstructured sources like social media interaction, posting or sharing reviews on the web page, mobile phones, and many more. Whenever a user visits the website using desktop, laptop, smartphones, PDAs, etc. generates the traffic. Also, downloading music and videos from various platforms generates unstructured data. This data can be filtered using analytics tool and extract important metrics that are useful for the business.


Velocity refers to the speed at which the data is coming in and how quickly the organizations are analysing and utilizing it. Processing the data using analytics tool can produce the answers to the queries through reports, dashboards, etc. With these results, a company can make suitable decisions that increase the efficiency and achieve customer-relation objectives such as developing applications that cater to the needs.


Different sources like social media, CRM systems, call center logins, emails, audio and video forms produce varied data. Managing such complex data is a big challenge for companies. However, to manage this big data, analytics tools are used to segregate groups based on sources and data generated. This would avoid mixing of data in the database.  It is important to segregate new and old data coming from varied sources and must be able to make the changes according to customer behaviour.


Veracity refers to an uncertainty of data available, which makes it harder for the companies to react quickly and make appropriate solutions. Accuracy is the major issue in such a big data environment. Organizing the data according to groups, value and significance will enable you to have a better strategy to use the data. Avoid mixing to related and unrelated data as this reduce mixed interpretation. To make right decisions, the data must be clean, consistent and consolidated.

Big data give insights about your customer base, views and opinions about your business. However, to solve business problems, the 4V’s – Volume, Velocity, Variety and Veracity must be used to measure the big data that helps in transforming the big data analytics to a profit-based center.

Selenium vs. HP Lean FT


Selenium is an open source tool and supports different types of languages such as Java, Python, PHP, C#, Ruby and pure JavaScript. Selenium, to a large extent, uses Java scripting and is the most influential Open Source Automation tool. It is ideal for the agile methodology of coding and testing.

Several advantages of Selenium testing are:

  • Selenium supports various languages such as Java, Python and PHP. It is the best tool for browser-based testing and handles all browsers such as IE, FF, Chrome, etc.
  • Selenium integrates to give a satisfactory framework for different verticals, like Maven or Ant for source code compilation; Test NG is used to drive tests, Jenkins to develop dashboards, and much more.
  • Jenkins in Selenium helps to connect the testers to multiple nodes and perform tests simultaneously.
  • Selenium is a freeware and can be easily integrated. Cost is a major advantage and the only cost to be spent is on human resources.

Disadvantages of Selenium include:

  • Organizations working on Selenium must invest on most experienced testers working in the same environment and an expertise in using the codes according to the standards.
  • Selenium supports only browser-based testing and fails to handle other window-based applications.
  • Selenium testers need not have to learn the tool from basics.

What a Business Analyst needs to know at the start of the project


Typically, an experienced business analyst is a liaison between the project manager and the project team members. During the beginning of the project, a business analyst must collect the most important information required for completing project. They are often called as an interpreter for project’s client ensuring that the requirements are gathered at the initial stage of the project. Below are some of the basic things that a business analyst must know before the start of the project.

Is the team ready?

Project managers along with business analysts are involved in the process of selecting the right team members. Every single member of the project team is given pre-defined roles enabling them to analyze their position and abilities to fit in this project. Business analysts must possess strong communication skills to communicate the roles and responsibilities to the team. At the same time, he or she must be a good listener to grasp any issues related to a project and the team.

Is the team technically equipped for this project?

As project is the mix of various fields, the team must consist of mixed talents to achieve completion with ease. By defining the roles and project requirements, analyst must be able to build a cohesive team. The team should be better assessed on the skills according to the project. Time can be saved later if the right team members are chosen at the beginning of the project.

Are the requirements defined?

For any project, solid requirements form the basis. These requirements include input from customer, stakeholders, project manager, and the management. Business analysts must understand the demand of the project and its budget. Requirements need to be detailed and documented. Since a business analyst acts as an intermediary, project manager depends on a business analyst to decide if the scheduled project fits the requirement.

Do they have problem-solving abilities?

A business analyst, project manager and the team members must possess the abilities to handle any issues involved within the project and the team. He or she may confront many technical challenges; a more realistic approach to solving any challenges can take the project forward. Proper planning helps to meet the requirements of both project and client.

Is training needed?

Certainly, a project is the technical implementation of skills that meets the requirements. Therefore, training would definitely enhance the skills and help in completing the project within the stipulated timeframe. Sometimes, customer training makes a difference to project like reviewing of requirements, project budget and timeline.

Eventually, it is necessary for the business analysts to be confident to provide a more realistic approach to the organization. A business analyst must generalize before the project is pulled off. Most schedules and decision-making skills are performed by business analysts. Transforming any small opportunity into a representative from and acquiring the project for the growth of the organization is made possible by an efficient business analyst.

Important Areas Where SAP HANA is implemented


Business cases where SAP HANA proved its efficiency

The first of the HANA deployments were the business cases that required real time analytics. For example, DataMart and Data Warehouses. Because, the benefits are there right out the box. Enterprise Data Warehouse (EDW) like SAP BW can run very fast with a simple database swap.

With a transactional application like Finance or Supply Chain, most things run a little better from a simple database swap (SAP claim 50% faster for their own core finance). The real benefits come when logic from the applications are optimized and pushed down to the database level, from simplification of the apps (SAP is building a simplified version of their Business Suite), or from ancillary benefits like real-time operational reporting, real-time supply chain management or real-time offer management.

Most importantly, unlike the other database systems in the market, HANA supports all applications on the same instance of data, at the same time.  Now, you can get rid of traditional copying, transforming and re-organizing data all over the enterprise to meet the needs of different applications. HANA perfectly serves the needs of all applications with one “system of record” instance.

What SAP Applications run on SAP HANA?

SAP CEO Bill McDermott says, ‘’HANA is attached to everything we have.’’

Today, all the major SAP Applications run on the SAP HANA platform. They include the SAP Business Suite (ERP, CRM, PLM, and SCM) and the SAP BW Data Warehouse.

The SAP HANA platform is designed to support the BI Suite which includes Business Objects Enterprise, Data Services and SAP Lumira.

SAP HANA powers a complete set of applications such as SAP Accelerated Trade Promotion Planning, SAP Collection Insight, SAP Convergent Pricing Simulation, SAP Customer Engagement Intelligence, SAP Demand Signal Management, SAP Assurance and Compliance Software, SAP Liquidity Risk Management, SAP Operational Process Intelligence and SAP Tax Declaration Framework for Brazil.

The cloud portfolio of SAP runs on HANA, along with the HANA Cloud Platform and SAP Business ByDesign. The latest set of apps which are on the verge of getting migrated to the HANA platform include Ariba and SuccessFactors Apps.Who should consider using SAP HANA?

An organization should strongly consider implementing SAP HANA, if:

  • There are few reports or analytic applications that are currently running very slowly and not getting the optimal business benefit.
  • They are constantly facing unacceptable downtimes, where your data warehouse is not available due to the need to load data.
  • They are in need to see current, till-the-moment data.
  • There is a frequent need to create new reports or analytical applications.

Even if organizations do not see a requirement for SAP HANA at this moment, they could still benefit from it, with a very thought of using it in the near future If they just go to their sales representatives of Oracle, or IBM, or Microsoft, and tell them that they are in the endeavour of migrating to HANA in the near future, they will be offered with a competitive price on licenses and also free maintenance of your current database. With this trend, it seems like soon most of the organizations will migrate to SAP HANA in the near future.
