Data warehousing on mysql

  • Can MySQL be data warehouse?

    Yes, MySQL can be used for data warehousing, but it is important to understand its limitations and considerations when using it for this purpose.Jul 25, 2019.

  • Can SQL be used as data warehouse?

    SQL Data Warehouse is a cloud-based Enterprise Data Warehouse (EDW) that leverages Massively Parallel Processing (MPP) to quickly run complex queries across petabytes of data.
    Use SQL Data Warehouse as a key component of a big data solution..

  • How is data stored in MySQL?

    MySQL stores each database (also called a schema) as a subdirectory of its data directory in the underlying filesystem.
    When you create a table, MySQL stores the table definition in a . frm file with the same name as the table.
    Thus, when you create a table named MyTable , MySQL stores the table definition in MyTable..

  • How is SQL used in data warehousing?

    SQL Data Warehouse stores data in relational tables using columnar storage which reduces the data storage costs, and improves query performance.
    SQL Data Warehouse leverages a scale-out architecture to distribute computational processing of data across multiple nodes..

    2. Step 2: Design the Dimensional Model
    3. Step 3: Design your Data Warehouse Schema
    4. Step 4: Implement your Data Warehouse

  • What type of data does MySQL use?

    The data type is a guideline for SQL to understand what type of data is expected inside of each column, and it also identifies how SQL will interact with the stored data.
    In MySQL there are three main data types: string, numeric, and date and time..

  • A data warehouse is a database of a different kind: an OLAP (online analytical processing) database.
    A data warehouse exists as a layer on top of another database or databases (usually OLTP databases).
  • For example, raw metrics might be stored in HDFS, but aggregated/summarized data is sent to MySQL for analysis.
    Second, MySQL can be used as a big data store.
    Typically MySQL will be sharded to support such large volumes of data.
  • MySQL stores geometry values using 4 bytes to indicate the SRID followed by the WKB representation of the value.
    The LENGTH() function returns the space in bytes required for value storage.
    For descriptions of WKB and internal storage formats for spatial values, see Section 11.4. 3, “Supported Spatial Data Formats”.
Data Warehousing (DW) is a process to collect as well as manage data from different sources to improve the ease of data access and deriving insights from this data. A Data warehouse is typically used to link and analyse organizational and transactional data from heterogeneous sources.

Can I use Python to build a data warehouse?

You can construct a data warehouse using any RDBMS, but some are designed with OLTP workloads in mind (MySQL)

PostgreSQL is more suited to analytical DW type workloads

You can certainly use MySQL or PostgreSQL for this requirement using Python as your database access language

I've never used Python cubes so I can't speak to that

Is Oracle Releasing a new MySQL database service for data warehousing?

In an announcement today, Oracle is unveiling an extended version of MySQL that takes it into data warehousing territory

It is releasing a new managed MySQL database service on Oracle Cloud Infrastructure (OCI) that will support both transaction and analytic processing workloads

That creates a key change for MySQL users
