Snowflake Data Lake and Its Advanced Features

Snowflake Data Lake  is an optimized cloud-based data warehousing solution offering unlimited storage and high computing facilities. You have the option of flexible data storage and can scale up and down whenever required by paying only for the quantum of resources used. This is helpful for businesses as additional investments need not be made in hardware or software whenever there is a need for more storage resources. Snowflake data lake   is a high-performing platform where multiple users can simultaneously execute multiple intricate queries without facing any lag or drop in speeds. Moreover, because of the extendable architecture of the Snowflake data lake, seamless loading of databases can be carried out within the same environment, thereby doing away with the need for specifying a data lake or a data warehouse to operate on. An example will explain this point better. D ata generated through Kafka can be transferred to a cloud bucket from where the data is converted to a columnar

Functioning of Data Lakes Built on Amazon S3

  Amazon S3 (Simple Storage Service) is a cloud-based and optimized data storage service, storing data in its native format regardless of whether it is unstructured, semi-structured, or structured. The durability of data in S3 is 99.999999999 (11 9s) and data in any volume is stored in a fully safe and secured environment. Many competencies can be used when an S 3 data lake   is built on Amazon S3. The critical ones are media data processing applications, Artificial Intelligence (AI), Machine Learning (ML), big data analytics, and high-performance computing (HPC). When all these are linked up, businesses get access to critical data and business intelligence and analytics from unstructured data sets as well as the S 3 data lake. There are several benefits of Amazon S 3 data lake. Computing and storage facilities are in different silos in S 3 data lake   and data in any format can be stored here. Compare this with traditional systems where computing and storage were closely interlink

The Working of Microsoft SQL Server CDC

  Modern-day businesses have to preserve historical data and take measures to prevent data breaches. In this regard, Microsoft took the lead in 2005 when it launched the SQL Server CDC. The 2005 version of SQL Server CDC   had certain flaws which were ironed out in an updated release in 2008. Some of the functionalities included tracking and capturing all changes that take place in the SQL Server database tables without taking the help of additional programs and applications. Till 2016, SQL Server CDC   was offered by Microsoft in its high-end Enterprise editions but later was available in the Standard version too. SQL Server CDC   captures and records all activities like Insert, Update, and Delete applied to a SQL Server. Column information and metadata required for posting changes to the target database are recorded in modified rows that are then stored in change tables representing the architecture of the columns in the tracked source tables. SQL Server CDC   also tracks all cha

The SAP BW Extractor and its Operational Features

  SAP BW Extractor   is a program that captures and prepares data in SAP ERP via an extract structure that can be transferred to the BW (Business Warehouse). The program may be customized or run from a standardized Data Source. Both instances define a full process load of various types or a delta load process. The data transfer facets of the SAP BW Extractor can be accessed remotely by the SAP Business Warehouse. Is all data lost if the SAP BW Extractor   is moved to S/4HANA or even other SAP BW Extractors that are compatible with S/4HANA? Only transactional and operational activities can be carried out and not analytics by the SAP ECC system. Thus, to analyze ECC data, SAP BW Extractor   is necessary to extract data from the SAP ECC system to an SAP BW system. After the SAP BW Extractor   is linked to a BW system, the latter can be made to perform analytical activities by connecting to the Business Intelligence system. Data extraction with SAP BW Extractor   is initiated by multip
