Learn to Store, Analyze Documents on Windows File System With SQL Server

The focus of the article is on comparing documents that can be stored on Windows File System in one respect and in the other respect their comparative analysis that can be performed with Semantic Search in SQL Server.

Additionally, the readers will learn how to store unstructured data by exploring File Table and creating MS Word documents on the fly (instantly) to be consumed by Semantic Search.

This part of the article is related to the use of Semantic Search on unstructured data for the extraction of basic level business-crucial information provided standard naming is in place.

Prerequisites

The readers need to go through **Learn to Store and Analyse Documents on Windows File System with SQL Server Semantic Search Part 1 **to proceed further with it.

This article assumes the readers are familiar with most (if not all) of the following:

This article also assumes that following steps have already been completed.

FILESTREAM Enabled Database EmployeesFilestreamSample has been set up.
File Table has been set up.
MS Word document **Asif Permanent Employee **and **Peter Permanent Employee **has been stored in a windows folder managed through File Table.
Querying the database File Table shows the information about the stored documents.

Please refer to the article Learn to Store and Analyse Documents on Windows File System with SQL Server Semantic Search Part 1 to complete any of the above missing steps, which are mandatory to cover the walkthrough completely.

Performing Name-Based Documents Comparative Analysis

As we are preparing to perform documents comparative analysis based on their standard naming, at this point it is worth doing a quick check by querying the FILESTREAM Enabled database we set up in the first part of the article.

Run the following script against EmployeesFilestreamSample database:

-- View stored documents managed by File Table to check
SELECT stream_id
      ,[name]
      ,file_type
      ,creation_time
FROM EmployeesFilestreamSample.dbo.EmployeesDocumentStore

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

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

Master
Model
MSDB
Tempdb
Resource

Master

This database contains all the System level Information in SQL Server. The Information in form of Meta data.
Because of this master database, we are able to access the SQL Server (On premise SQL Server)

Model

This database is used as a template for new databases.
Whenever a new database is created, initially a copy of model database is what created as new database.

MSDB

This database is where a service called SQL Server Agent stores its data.
SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.

TempDB

The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
User can create their own version of temporary tables and those are stored in Tempdb.
But this database is destroyed and recreated every time when we restart the instance of SQL Server.

Resource

The resource database is a hidden, read only database that holds the definitions of all system objects.
When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.

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.

Learn to Store , Analyze Documents on Windows File System with SQL Server

Being the final part of the article, it is going to take you to the next level of analyzing word documents stored in Windows folders, managed by File Table, and consumed by Semantic Search.

Additionally, the readers are going to gain more understanding of Semantic Search and how to make it work with MS Word documents for analysis.

This article provides a name-based analysis of the documents with equal attention to both theory and practice.

Prerequisites

This article assumes the following:

The readers are familiar with the following concepts:
File Table(s).
Semantic Search.
Full-Text Search.
All the prerequisites and **FILESTREAM Enabled EmployeesFilestreamSample **database have been set up.
**EmployeesDocumentStore File Table **has been set up
The following documents have been added to the File Table:
Asif Permanent Employee – Experienced Project Manager.
Mike Permanent Employee – Fresh Programmer.
Peter Permanent Employee – Fresh Project Manager.
Sadaf Contract Employee – Experienced Business Analyst.
The readers can perform some simple Semantic Search operations against the stored documents.

I suggest that you go through the following articles to fill any gaps in your understanding of the above prerequisites and to implement the walkthrough(s) in the final part of the article:

Part 1 Review

In the first part of the series we learned about the following things:

Setting up a FILESTREAM database.

Saving MS Word Documents in a File Table.
Viewing MS Word Document by running a T-SQL script.

Part 2 Review

Running Full-Text queries against the stored documents.
Adding more MS Word Documents.
Counting of Documents.
