i am using Microsoft SQL Server Management Studio. I though it was a database management system, until today I realized that the database management system is actually Microsoft SQL Server.
So i would like to know what relation and differences are between Microsoft SQL Server Management Studio and Microsoft SQL Server.
I learned that Microsoft SQL Server Management Studio is a database administration tool, from https://en.wikipedia.org/wiki/SQL_Server_Management_Studio. So what are the differences and relations between database administration tool and database management system?
Does a database management system include user interface?
(I know that a database administration tool does, based on my experience with Microsoft SQL Server Management Studio.)
Can I draw an analogy in programming languages?
Does a database management system act like the compiler of a programming language (here SQL language)?
Does a database administration tool act like the IDE for developing programs in a programming language?
I still can't figure that out after reading the following links.
From the second link:
A database management system (DBMS) is a computer program (or more
typically, a suite of them) designed to manage a database, a large set
of structured data, and run operations on the data requested by
numerous users. Typical examples of DBMS use include accounting, human
resources and customer support systems.
From
https://en.wikipedia.org/wiki/Database_administration_and_automation#Database_administration_tools
Database administration tools
Often, the DBMS software comes with certain tools to help DBAs manage
the DBMS. Such tools are called native tools. For example, Microsoft
SQL Server comes with SQL Server Management Studio and Oracle has
tools such as SQL*Plus and Oracle Enterprise Manager/Grid Control.
In
addition, 3rd parties such as BMC, Quest Software, Embarcadero
Technologies, EMS Database Management Solutions and SQL Maestro Group
offer GUI tools to monitor the DBMS and help DBAs carry out certain
functions inside the database more easily.
Thanks.
So what are the differences and relations between database administration tool and database management system?
The differences are that a DBMS is essentially the engine that the database is running on. This essentially boils down to how the data is stored, managed, and queried.
While most DBMS engines share the core ANSI-standard SQL querying capabilities, each DBMS product (e.g. SQL Server, MySQL, Oracle, etc.) has different, DBMS-specific syntax that can also be used in the queries.
Does a database management system include user interface?
Not any one that I'm aware of. A DBMS is just the engine that drives the database and processes queries.
To contrast, a Database Administration Tool is a tool that can be used to access the database, manage database components, and execute queries. In most cases, this is a GUI (an example is SQL Server Management Studio). A Database Administration Tool does not run the database, but rather, gives you a way to visually see, query, and manipulate the data being hosted by the DBMS.
Database Administration Tools can be 3rd party software, and they usually come with the DBMS as well (as you pointed out in your question).
Does a database management system act like the compiler of a programming language (here SQL language)?
It does, yes. Among its other tasks, a DBMS engine accepts, compiles, and executes incoming queries.
Does a database administration tool act like the IDE for developing programs in a programming language?
Yes - it provides a visual representation of the database and also provides intellisense to aid query construction.

I have been using Microsoft SQL Server 2017 for a while (just DDL and DML) and recently decided to install JetBrains DataGrip because I thought it was another DBMS but with dark theme.
When I try to create a new database it tells me to assign a host/user/password/port and I cannot do anything because it can't "connect to the database". I've been using Microsoft SQL Server Management Studio 2017 and never needed to assign a port/password/host or anything? I just created a new database and started adding/filling tables. How does JetBrains DataGrip work?
I noticed that on the JetBrains DataGrip page it doesn't say it's a DBMS, it says it's a "Database IDE". I cannot seem to find information about this on the web.
When considering a RDBMS such as SQL Server, the core component is a service/engine which acts as an interface between the database (files) and end users or applications allowing database functions to be carried out.
SSMS (SQL Server Management Studio) is just one of many possible end users of the SQL Server Database, and happens to have be part of the SQL Server software suite. It should not, however, be confused with the database itself as SQL Server operates perfectly happily without ever seeing SSMS.
Any form of user interface tool for a database needs to know how to connect to the database it is going to manage. In your case you most likely installed the entire software suite with default settings and as such didn't need to know what they were. JetBrains DataGrip however does need these settings.
You can find out what your specific settings are by running the SQL Server Configuration Manager.
JetBrains DataGrip is just a Database IDE to connect to different database engines via only one environment without needing to install management tools for every database that you want to work with.
My company's product has a big relational database storage(around 20 TB) and we want to move all or some part of our database. Now I am a bit confused regarding which cloud SQL service will be suitable for me. I have read that some cloud storage only provides specific SQLs like MySQL ... which I cannot afford, the reason is that here we have lots of Transact-SQL scripts on our MSSQL server, which periodically updates the data.
So what should be my basic approach to achieve that, How can I compare between various cloud-based relational database storage like Google Cloud SQL, Azure SQL and Amazon RDS?
If your existing SQL server is Microsoft SQL Server then it probably makes the most sense to use a Microsoft SQL server offering in a cloud environment. That will help minimize any sorts of compatibility issues and also minimize the need to learn a new SQL server environment.
Amazon's RDS service lets you choose between various versions of MySQL, Postgres, Oracle, and Microsoft SQL Server. With regards to Microsoft SQL Server, Amazon offers an express edition, as well as SE and EE versions. As far as licensing goes, they offer both "bring your own" as well as pay-by-usage licenses. More information on the license details can be found in their RDS documentation. They also have a usage calculator that lets you estimate what your monthly costs will be based on the license you use, the size of the instance, etc.
Since Azure SQL is a Microsoft product I would hope that it's compatible with Microsoft SQL Server but I have never used it so I honestly have no idea if there are any compatibility issues. Microsoft also has some basic pricing information available for Azure SQL so you can work out an estimate of your costs if you go with them.
If you're concerned about any scripts working properly on one of the cloud platforms then I'd suggest creating a small test database that you can thoroughly test those scripts with. Upload that test database to the different clouds and test the scripts there to ensure they function properly. Amazon offers a very light-weight RDS instance for free so you can do basic testing without it costing you anything. Perhaps Azure offers something similar. Even if they don't or the free RDS instance isn't powerful enough for your testing needs, spinning up an instance for a day or two to run these sorts of tests shouldn't cost you very much.
I am getting a little bit confused about the difference of the followings:
SQL Server Express
SQL Server Compact
localDB
My requirement is to develop a desktop application that will use basic RDBMS features. I need to package the application and allow the user to install a single distributed package. I don't want the user to install even SQL server express.
In this case, which DB I should use? SQLite is not considered as too much re-coding has to be done.
Thank you.
SQL Server Express is full featured DBMS, with some limitations in terms of database size and resources it is allowed to use. You can see it's limitations (relative to SQL Server) on microsofts site (Features Supported by the Editions of SQL Server 2012)
SQL Server CE is embedded database, meaning that it runs in user mode, it's easy to deploy (requires you to copy just few assemblies), lightweight but fast, can be run by a low privileged user. It's supported by NHibernate. However, has more limitations. To me most notable is that there are problems when you try to have multiple connections to same database. Although MS claims that this is supported, if you try this in Windows 2008 server, you will fail. And what's worse, such use scenario may lead to DB corruption. This means that you will effectively not be able to use some Management tool to update data while your service/website is running. Also, SQL Server Management studio doesn't support SQL CE anymore, so you will have to use a 3rd party tool, like Database.NET. It also does not support subqueries.
localDB, having not used it, sounds like a compromise. It's a standalone database which is executed in user mode (can be used by low privilege user), but must be installed so you will need administrative privileges for that part. Offers set of capabilities of SQL Server Express. It's much larger than SQL CE, and also requires to be installed (unlike CE which is just binary drop in). Shortest overview of this DBMS can be found here.
I have a project requirement to choose a light database for the application.
It's required to choose between SQL Server Express Edition or SQLLite. Which one would be efficient and reliable. I am supposed to run it under Windows 7/Windows 2008 R2. I am newbie in the database programming. It would be helpful if you can share some information in terms of
Reliability
Stability
Size Limits
Memory consumption
Performance
SQL Server Express and SQLite aren't really comparable database systems.
SQL Server Express is the free version of Microsofts full SQL Server product, a standalone database server (often run on a dedicated machine) that client applications connect to. It is designed for things like web applications where many users will be using the database at the same time and there is a requirement for high availability.
SQLite is a compact in-process database that is often used in applications that benefit from having access to a SQL based database system however it isn't feasible to install a full standalone database alongside the application. For example Firefox uses SQLite to store bookmarks and Adobe Lightroom uses it to store its photos catalog, there are also several mobile (e.g. iPhone) applications that use SQLite.
The Microsoft equivalent to SQLite would be SQL Server compact edition (CE) which is free to distribute and use. SQL Server CE is very similar to SQLite in most respects.
Similarly the non-Micrososft equivalent of SQL Server (both the Express edition and the full edition) would probably be MySQL.
Although there are crossovers (you might build a small web application that uses SQLite, or a large desktop application that requires users to install SQL Express) typically the choice between the two "types" of database system (in-process vs standalone database server) is down to the type of application being developed.
You might find more details in the following article: http://erikej.blogspot.com/2011/01/comparison-of-sql-server-compact-4-and.html
I've got experience with MySQL, DB2, and Oracle, but aside from writing a few queries, I've never used SQL Server.
My question is a three parter:
1) For a developer, what are some good "free" client tools to look at, and why (by "free" I mean open source, freeware, or the tools that come with SQL Server itself)?
2) I plan to run Developer or Express Edition on my workstation for development, and either Standard or Enterprise Edition in the testing and production environments. What methods exist if any for transferring data between different servers and the different editions?
3) Are there any common pitfalls that someone like me (who is used to the other database systems that I mentioned) might encountered during development?
TIA
SQL Server Express with tools.
All editions have the same SQL language features and code is 100% portable between them. There are 3rd party tools to synch changes, but moving entire DBs is easy using inbuilt tools.
Nah. The problem with databases is SQL and set theory, not the choice of RDBMS. If you understand databases/SQL you'll be OK.
SQL Server Management Studio which comes with SQL Server (any editions), or you can download it separately. SQL Server Profiler which doesn't come with Express.
Management studio has tools for backup/restore database. You can also consider detach/attach method to synchronize db .
It's hard to say. But if you had Mysql experience you will be pleasantly surprised by SQL Server.
UPDATE
There are so many things that each DB vendor implements differently that it's really hard to focus on some of them. One thing I was not used before is that SQL Server doesn't let unique columns to have more than 1 NULL value(there is a workaround though)
