File1:

A database management system (DBMS) is a system software for creating and
managing databases. The DBMS provides users and programmers with a systematic
way to create, retrieve update and manage data. A DBMS makes it possible for
end users to create, read, update and delete data in a database.
The DBMS essentially serves as an interface between the database and end users
application programs, ensuring that data is consistently accessible

The DBMS is perhaps most useful for providing a centralized view of data that
can be accessed by multiple users, from multiple locations, in a controlled
manner. A DBMS can limit what data the end user sees as well as how that end
user can view the data, providing many views of a single database schema.


End users and software programs are free from having to understand where the
data is physically located or on what type of storage media resides because
DBMS handles all requests,

The DBMS can offer both logical and physical data independence.
That means it can protect users and applications from needing to know where
the data is stored or having to be concerned about changes to the physical
structure of data. As long as programs use the application programming
interface for the database that is provided by the DBMS, developers wont
have to modify programs just because changes have been made

With relational DBMS (RDBMSs), this API is sql, a standard programming language
for defining, protecting and accessin data in a RDBMS.

My experience with DBMS is decent. I have a job as a DBA or Database admin
I work from both at a cubical and or at home when I cannot make it to the MC
I mostly work with SQL Server or Transact SQL. This is a Microsoft owned
language that is coused with Azure Database. It is coded in SQL SERVER
MANAGEMENT STUDIO.

Along with knowing SQL, I must know how to use Microsoft Visual Studio
Knowning how to use ETL, (Extract, Transform and Load) This is used with the
software SSIS or SQL Server Integration Services. This is a software to perform
broad range of migration tasks, for workflow and applications.

It is also good to know XML and HTML. For creating and editing landing pages
for easy directory access to pages that our company uses every day.
Such as AIM, Capacity Planner, IMAT, Scheduling Decision Board and so on
Knowing how these tool work is a big part of being a DBA it is not just
Knowing how to create and control data in a Relational Database

A big part of supply chain is to know the business as well as you know
the technology. You will not know what to write in a Database if you
do not know what it is used for. Also you cannot understand the need
and then make mistakes that will need to be rolled back with a transtion.
You mostly work with views and tables joining them together to see what
data is going where.

All in all this is fun but tedious work. Managing systems is an important thing
to look out for as one mistake can make your company lose all its data and
could cause them to start from scratch or shut down

T-SQL (Transact-SQL)or SQL Server is a set of programming extensions from
Sybase and Microsoft that add several features to the Structured Query
Language (SQL) including control, exception and error handling, row processing
and declared variables

All applications that communcate with SQL SERVER do so by sending T-SQL
statements to the server. T-SQL queries include the SELECT STATEMENT, selecting
columns, labeling output columns restricting rows and modifying a search
condition.

T-SQL identifers, meanwhile are used in all databases, servers and objects
These include tables, constraints, stored procedures, views, columns and data
types. Each must have a unique name, are assigned when an object is created
and are used to ID an object.

The most popular T-SQL statement is the stored procedure, which is a compiled
and stored SQL code. Similar to views, stored procedures generate an execution
plan when called the first time, the difference is stored procedures can
select data and execute any code within an parameters

SQL SERVER also supports analytical functions to depict complex tasks
These enable pros to perform common analysis, such as ranking, percentiles
moving averages and sums to be expressed in a single SQL statement.
