SHREE PHARMACEUTICALS LTD.

Dear X(Software Developer),

SUBJECT: – To develop software which enables online tracking and ordering of inventory, which will enable to optimise level of inventory production.

DESCRIPTION:-

As mentioned in the subject, our company wants to prepare software from your company for online tracking and order acceptance, in order to improve production level as well as maintenance of inventory.

Some of the details about the company are as follows:-

1. Company is having 20 sales staff and everyone will have one PDA device which will help for online tracking.

2. Company is having 6 types of products:- Injection,Tablets,Capsules,Cream,Suspension,Syrup

3. Company is having one central warehouse which contains finished inventory of above products.

4. Company is having set up of WAN which will cover its clients(DISTRIBUTORS) as well as it would also provide access to PDA devices which will be given to sales staff for receiving of order.

5. Company is also having one server in the warehouse which would support its maintenance of database of clients and other processes.

Hopefully, above provided information will be enough to get idea about the kind of software which our company wants. For any further assistance contact to my secretary.

Regards,

Avadhut Kaluskar

A compiler is a computer programme (set of programmes) that translates text written in a computer language (source of language) into another computer language (the target language). The original sequence is usually called the source code and the output called object code. Commonly the output has a form suitable for processing by other programmes (e.g. a linker), but it may be human readable text file.

Towards the end of the 1950s, machine-independent programming languages were first proposed. Subsequently, several experimental compilers were developed. The first compiler was written by Grace Hopper, in 1952, for the A-0 programming language. The FORTRAN team led by John Backus at IBM is generally credited as having introduced the first complete compiler, in 1957. COBOL was an early language to be compiled on multiple architectures, in 1960.

In many application domains the idea of using a higher level language quickly caught on. Because of the expanding functionality supported by newer programming languages and the increasing complexity of computer architectures, compilers have become more and more complex.

Early compilers were written in assembly language. The first self-hosting compiler — capable of compiling its own source code in a high-level language — was created for Lisp by Hart and Levin at MIT in 1962. Since the 1970s it has become common practice to implement a compiler in the language it compiles, although both Pascal and C have been popular choices for implementation language. Building a self-hosting compiler is a bootstrapping problem — the first such compiler for a language must be compiled either by a compiler written in a different language, or (as in Hart and Levin’s Lisp compiler) compiled by running the compiler in an interpreter.

 PROCEDURE TO RUN SQL QUERIES:

As given in part A, I have created Zoho account. And copied database of company ANGSTROM PVT. LTD. From excel sheet to zoho page via IMPORT OPTION. Then on main page two files of EMPLOYEE and DEPARTMENT appeared. After that, in NEW button, I clicked on NEW QUERY to run new Query and then wrote a code as per the SQL language requirement and then got the result of Query as I wanted to be. This procedure is followed for all queries. And the detailed description of each query is as follows:

1.      JOIN QUERY:

In this i wrote code as follows:

SELECT “EMP”,”LAST ANME”, “FIRST NAME”,”LOCATION” FROM

“EMPLOYEE”,”DEPARTMENT” WHERE “EMPLOYEE”.”DEPT”=”DEPARTMRNT”.”DEPT”

 In above query the result was based on joining of the two separate tables of EMPLOYEE and DEPARTMENT. Where output is having joining of two tables by cancelling common part of department id.

2.      STANDARD DEVIATION QUERY:

Code is as follows:

SELECT stddev (“SALARY”) from “EMPLOYEE”

In this query , there is function of INSERT having option of SQL FUNCTIONS, where i selected stddev option which gave output table having the standard deviation of salaries form EMPLOYEE table.

3.      BRACKET PLUS “AND” and “OR” :

Code is as follows:

SELECT “LAST NAME”,”FIRST NAME”,”JOB DESCRIPTION”,”SALARY” FROM “EMPLOYEE” WHERE ( “JOB DESCRIPTION”=’CUSTOMER REPRESENTIVE’OR “JOB DESCRIPTION”=’CLERK’) AND “SALARY” >= 5000

Where output table is having job description of “customer representative” plus “clerk” whose salaries are more than equal to 5000.

4.      QUERY CONTAINING SAME DEPARTMENT BUT HAVING DIFFERENT SALARIES:

SELECT  ”LAST NAME”, ” FIRST NAME “, JOB DESCRIPTION “, “SALARY”, “DEPARTMENT” FROM “EMPLOYEE” WHERE “DEPARTMENT”= ‘10′ AND SALARY > 5000.

In this output, the department which is having id ‘10′ got selected and out of which those who are having salaries more than 5000 got selected.

SYSTEM ARCHITECTURE 

Introduction:-

Ajay: He is my friend just passed his 12th and seeking admission in engineering(specially intersted in IT). He has sound knowledge of IT as it was one of his vocational subject in 12th.He read one article about System architecture and then asked me about it. and our convesration went as followed after formal introduction:

Ajay: What is system engineering and system architecture????

Me:Its simple.Do you know in progarmming language, what is data structure and algorithms???

Ajay:Yes, data structure is brief of what is to be processed and algorithms is supportive method or process of how this data is to be processed. right??

Me: Correct. similarly in system engineering(science comprises of developement of complex arificial systems), system consist of database(what is to be processed) and applications(how to process). and these 2 entities are always seperated in any system. and designing  these enitities efficiently for perticular project is called as system architecture(SA). 

Ajay:  Ok. now picture is getting somewhat clear.do you have some more information ????

Me:Yes, of course.There are several types of SA depending upon complexity and several other factors:

1)Single tier

2)Two tier

3)Three tier

and 4) Multi tier

in all this tiers (except single tier)basic thing is data is stored in one system called as servers while applications are stored either at client end or at main data center. and these two are integrated with help of internet,WAN,LAN etc. and while integration main challange is data security.As you must have heard about hackers so companies now a days use security tools such as firewall which protects data theft.

Ajay:Wow! that sound interesting. now a days i heard about ERP and DBMS. what are they would you please explain me in short?? and is it having any relation with SA??

Me: Yes, they are related as to SA. these are the two hot topics in IT world now, which eases companies handling data in efficient and structured way.where DBMS is related to database management while ERP is related to applications containing different modules. 

Ajay: I think these things are interesting.

Me: Ya definately these things are now emerging slowly.hope above information will help you to choose your engineering stream.

Ajay : Yes, sure, thanks a lot. bye

Me: Bye and best of luck.
