Enterprise Solutions Chapter 11 – In-memory Technology

Introduction Faster and easier access to the information is what is required in today’s Business and therefore need for in- memory technology. Traditional technology loads data into hard drives/disks in order to make it easy for frequent use. In-memory makes use of computer RAM to achieve it in a better and faster manner It helps in query analysis, cube building and table design for software programmers.

Drawbacks of Traditional BI 3By: Varsha Godbole 11 – In-memory Technology Requires optimization of database and aggregation of tables. Lack of performance factor in optimization techniques Limited amount of data or information was made available to users. Predetermined data queries were used to fulfill end users need.

Advantages of In-memory Processing 4 More real data is presented to end user in the form of dashboards. Creating custom reports and queries is possible. Maximum utilization of databases with the help of in- memory population of records/data. Easy navigation and ability to prepare the queries on the fly. User feels like he is working with real-time data. Helps in fast decision making. By: Varsha Godbole 11 – In-memory Technology

How to use In-memory processing 5By: Varsha Godbole 11 – In-memory Technology Column-centric databases are used to store data more efficiently and in a compressed manner. This allows storing huge amount of data in same physical space which reduces memory required to perform a query and increases the processing speed. All the information initially required is loaded into in- memory databases. Improvement in accessing the data is 10,000 to 1,00,000 times faster than from a disk.

Factors driving In-memory products 6 Cheaper and higher performance hardware 64-bit operating system Data volumes Reduced cost By: Varsha Godbole 11 – In-memory Technology

Typical users 7 Organizations where there is significant growth in data volume and increase in demand for reporting functionalities that facilitate new opportunities. Utmost care should be taken when it comes security part of the underlying data. One way to achieve security is to allow only authorized users to access the data By: Varsha Godbole 11 – In-memory Technology

Limitations 9 With increasing number of users who will connect to the application and large amount of data handling, the size of RAM required to achieve faster and easier access increased which in turn increases the cost of the hardware. By: Varsha Godbole 11 – In-memory Technology
