SQL Server Indexes Management Using Index Manager for SQL Server

When talking about SQL Server performance tuning and queries enhancement, the first thing to consider is the SQL Server Index. It serves to accelerate reading data from underlying tables by providing quick access to the requested rows. Thus, it won’t need to scan all the table’s records.

The SQL Server index provides those fast search capabilities due to the B-Tree structure of the index. This structure makes it possible to move through the table rows based on the index key quickly and retrieve the requested records at once. It won’t need to read the whole table.

SQL Server indexes’ types

Among the main types, we pay attention to the clustered and non-clustered indexes.

The **Clustered index **sorts the actual data in the data pages according to the clustered index key values. It stores the data at the “leaf” level of the index, ensuring the possibility to create only one clustered index on each table. The clustered index is created automatically when a Primary Key constraint appears on the heap table.

The **Non-clustered index **contains the index key value and a pointer to the rest of the row columns in the main table. It is the “leaf” level of the index, with the ability to create up to 999 non-clustered indexes on each table.

Introduction to Structured Query Language SQL pdf

SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.

Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:

1. The SQL order standard is genuinely intricate, and it isn’t handy to actualize the whole standard.

2. Every database seller needs an approach to separate its item from others.

Right now, contrasts are noted where fitting.

Python Packages in SQL Server – Get Started with SQL Server Machine Learning Services

Introduction

When installing Machine Learning Services in SQL Server by default few Python Packages are installed. In this article, we will have a look on how to get those installed python package information.

Python Packages

When we choose Python as Machine Learning Service during installation, the following packages are installed in SQL Server,

  • revoscalepy – This Microsoft Python package is used for remote compute contexts, streaming, parallel execution of rx functions for data import and transformation, modeling, visualization, and analysis.
  • microsoftml – This is another Microsoft Python package which adds machine learning algorithms in Python.
  • Anaconda 4.2 – Anaconda is an opensource Python package

SCHEMAS in SQL Server -MS SQL Server – Zero to Hero Query Master

Introduction

This is part 3 of “MS SQL Server- Zero to Hero” and in this article, we will be discussing about the SCHEMAS in SQL SERVER. Before getting into this article, please consider to visit previous articles in this series from below,

A glimpse of previous articles
Part 1

In part one, we learned the basics of data, database, database management system, and types of DBMS and SQL.

Part 2
  • We learned to create a database and maintain it using SQL statements.
  • Best practice methods were also mentioned.

Get Started with SQL Server Machine Learning Services

We know Humans learn from their past experiences. Mean while Machines follow Instructions given by Humans. But what if Human can train Machines to learn from the past data?. In simple, this is what Machine learning is !!!. SQL Server has capabilities of Machine Learning. In this article, we will discuss about the capabilities of Machine Learning in SQL Server.
