Big Data technologies and the development of Internet applications have become the biggest trend + era. It also makes a lot of people have chosen to study large data, get a world of their own in the trend of the era. Huge big data technology system, including more knowledge, learning big data system allows you to fully grasp the big data skills.
First, before starting to learn the basics of what big data should grasp
How big data entry fast learning? What is the basis of need
1, Java language foundation
First learning a computer programming language to learn before the big data programs. Java is a great programming language to learn the necessary data base. Because the development of large data based on the Java language, and whether it is learning hadoop, or data analysis and mining, needs to have a programming language as a basis. So, if you want to learn big data development, grasp the Java foundation is essential.
Of course, Python is also possible, but the Python language is more interested in machine learning, artificial intelligence and other aspects of deep learning. Big Data technology, Java is more suitable.
In the process of getting started big data have met learning, industry, the lack of systematic learning path, learning systems planning, you are welcome to join my big learning data exchange skirt: 251 956 502, skirt documents have my years of study manual sorting of large data , development tools, PDF document with a book, you can download yourself.
2, mathematical knowledge
Furthermore, is learning to use big data requires some mathematical knowledge.
Mathematical knowledge is the basis of knowledge of data analysts.
For primary data analyst to understand some basic descriptive statistics related to the content, there is a certain formula to calculate the capacity to understand the common statistical model algorithm is a plus.
For senior data analyst, a statistical model of knowledge is an essential capability, linear algebra (matrix calculation is mainly related knowledge) there is a certain understanding.
For data mining engineers, in addition to the statistics, various algorithms also need to skillfully use, the requirements of mathematics is high.
3, logical thinking ability
If this math is good, or usually like logical thinking, the general logical thinking ability is there. In big data analysis and data mining need to use logical thinking. When learning Java, it uses logical thinking ability, so learn Java also exercise the logical thinking ability.
Second, the large data need to learn what technologies
1、Linux
2、Hadoop
3, HDFS system
4、Hive
5, Storm real-time data processing
6、Hbase
7, Redis cluster
8、spark
9, Docker technology
10、Kafka
