Role of SQL in Online Database Management

Data is the backbone of every organization, regardless of sector it belongs to and the size. Every company realizes the importance of data, and wants to implement a robust database. And with everything going digital, DMS or Database Management is also now online.

What is database?

A systematic collection of data, is known as database and it supports storage and management of data. Starting from your social media websites, to the telephone directories, everything is based on database.

It makes management easy, and collaboration more seamless.

What is online database management?

A database which is accessible from a local network or the Internet is known as online database management. In contradiction to the traditional methods, database is no more stored locally on an individual computer or it is not attached to any storage device such as a CD. Everything is now on the cloud and can be accessed from anywhere. They are secured with login id and passwords and have access rights restrictions. You can host online databases on websites, make them available too your stakeholders through a software as a service products accessible via a web browser.

SharePoint is one such DMS from Microsoft and it comes with loads of benefits:

• Makes collaboration easier and thus fastens day-to-day activities within the organizations
• Manage sensitive data with embedded settings.
• Content can be prepared and hosted both on the intranet and the internet.
• Customize database and give access to users of the required data only.
• Share workflow seamlessly with employees and keep everyone on the same page.
• Technologies such as XML, and SOAP can be easily integrated to provide numerous robust APIs.

Role of SQL

Structured Query language or SQL is a database management language, precisely it is the standard language for relational databases. It can not only help in maintaining and optimizing the databases, it also helps in inserting, searching, updating, and deleting database records.

Though SharePoint is itself not a database, it looks a lot similar to SQL Server as sits on it. With the help of experts, you can get highly customized portals, which can efficiently handle workflows, and enrich customer experience. But, if you try to build complex relationships between tables and data stored, it will lead you nowhere.  

Query – An integral feature of Microsoft Access Database Management

A query is a helpful and robust feature of Microsoft Database management which is used to view, add, delete, or update data.

Some reasons for using query are:

• With the increase in data, tables start growing in size, and there can be hundreds of thousands of records in each table. So, finding the required information from these become impossible. You can use query to find out the specific data using conditions or criteria.
• You can use queries to retrieve data from a table or to perform calculations or to summarize data.
• Using queries you can add, alter, or delete data.
• You can automate the tasks which are done repeatedly.
• You can use it to pull data from the tables for a form or report.

Queries make Microsoft Access easy to use.

Because of the pictorial representation of tables and the relationships between them, it becomes easy to create queries in Microsoft Access, and one can write queries without getting into the complexities of writing the raw Microsoft Access SQL. If you are acquainted with the features of queries, you can perform advanced analysis quickly without possessing any programming skills.

Being developed on SQL systems, it is easy to switch between query design and SQL syntax. Many developers and users use this platform to learn SQL syntax.

Furthermore, at an advanced level and for developing complex applications, developers prefer using VBA and SQL language.

Major types of queries

Select query

This simplest type of query is widely used to retrieve and display data from either one or more tables.

Action Query

Using action queries, you can make changes to many records at one time instead, and thus, it saves a lot of time.

Four types of action queries include:

• Append query to append data to an existing table.
• Delete query to delete all records from a table.
• Make Table Query to create tables.
• Update Query to update an existing set of data.

Parameter Query 

This type of query accompanies the other types of queries, and it specifies the other query Access database what you want it to do.
