3. Architecture Feasibility

3.1.1 Feasibility Evidences for Pulling Information Module

The most critical part of our project is communication with PubMed. PubMed is a database of

members’ articles (members are the users of the project application). So before doing anything

we should do some prototyping to make sure that this module is going to work properly.

NCBI (National Center for Biotechnology Information which owns PubMed) provides an API

(Entrez Programming Utilities) to work with PubMed database. This API consists of many tools

which let us to have access to the articles’ XML files, search through PubMed and etc.

At the beginning of the development phase we decided to use this Entrez API. Later we found

that this API is very limited so we shifted to another API called PubMedAPI or “PubMed

Wrapper” (discussed in the below). In the below we first describe the Entrez API and then we

will discuss about PubMedAPI (PubMed Wrapper) which is the API that we actually used for

fetching the information from PubMed.

1. Entrez Programming Utilities The Entrez Programming Utilities (E-utilities) are a set of eight server-side programs that

provide a stable interface into the Entrez query and database system at the National Center for

Biotechnology Information (NCBI).

The E-utilities use a fixed URL syntax that translates a standard set of input parameters into the

values necessary for various NCBI software components to search for and retrieve the requested

data. All E-utility requests should be made to URLs beginning with the following string:

http://eutils.ncbi.nlm.nih.gov/entrez/eutils/

To access these data, a piece of software first posts an E-utility URL to NCBI, then retrieves the

results of this posting, after which it processes the data as required. The software can thus use

any computer language that can send a URL to the E-utilities server and interpret the XML

response; examples of such languages are Perl, Python, Java, and C++. Combining E-utilities

components to form customized data pipelines within these applications is a powerful approach

to data manipulation.

Entrez Program Interfaces

ESearch utilitiy

FED_IOC1_S13b_T01_V6.0 Version Date: 05/03/13

eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi

Responds to a text query with the list of matching UIDs in a given database (for later use in

ESummary, EFetch or ELink), along with the term translations of the query.

ESummary (document summary downloads)

eutils.ncbi.nlm.nih.gov/entrez/eutils/esummary.fcgi

Responds to a list of UIDs from a given database with the corresponding document summaries.

This part consists of some feasibility evidences about our most risky module (pulling

information from PubMed).

EFetch (data record downloads)

eutils.ncbi.nlm.nih.gov/entrez/eutils/efetch.fcgi

Responds to a list of UIDs in a given database with the corresponding data records in a specified

format.

ESpell (spelling suggestions)

eutils.ncbi.nlm.nih.gov/entrez/eutils/espell.fcgi

Retrieves spelling suggestions for a text query in a given database.

Syntax and Initial Parsing of Entrez Queries

term1[field1] Op term2[field2] Op term3[field3] Op

Example: human[organism] AND topoisomerase[protein name]

esearch.fcgi?db=<database>&term=<query>

Input: Entrez database (&db); Any Entrez text query (&term)

Output: List of UIDs matching the Entrez query

Example: Get the PubMed IDs (PMIDs) for articles about breast cancer

published in Science in 2008

The next things that we are going to do are some advance fetching/searching from and in

PubMed database.

2. PHP-Pubmed-API-Wrapper

PHP-PubMed-API-Wrapper

This is a new developed API-Wapper which we used in our project as a new way in

communication with PubMed. This API is developed by third party developers. They

tried to solve some problems of PubMed original API (Entrez). This API gave us more

reliability.

This API is accessible through this link:

https://github.com/asifr/PHP-PubMed-API-Wrapper

A modified version of this API is also available in the project source code

(PudMedAPI.php). This file is documented by the original authors. The PTS-RID

developers also added comments for the modified parts of the code.

We modified this API because we needed to fit this API with our project (e.g. the original

version of this API doesn’t pull all the information that we really needed so we had to

modify this API to make it to pull all the information which we really needed)

Feasibility Evidence Description (FED) for Architected Agile Version 6.0

FED_IOC1_S13b_T01_V6.0 Version Date: 05/03/13

Pubmed Module Codes:

The Pubmed Module consists of two php files which are available in the PTS-RID source code:

1. PudMedAPI: Which is the modified version of the (PHP-Pubmed-API-Wrapper).

2. pudmed.php: Which does the whole functionality of pulling information:

Reading User’s information from local database (user table)

The for each user the code goes to the Pubmed website and fetch all of hir/her article’s

information

Then the code populated the relational local database.

These two php files are well commented and are available in the PTS-RID source code.

3.2 Level of Service Feasibility

Part 3.2, 3.3, 3.4 consist of products strategies and processes strategies that we can use to achieve

each requirement.

Table 5: Level of Service Feasibility

Level of Service

Requirement

Product Satisfaction

LOS-1: Support 200 users,

100 concurrently

Product Strategies: Database Optimization (Code/Algorithm), Using

well-known host/database server

Process Strategies: Doing some prototypes to simulate a situation in

which 100 concurrent users are working on the database (maximum 200

users) by using SQL procedures and optimized algorithms.

Analysis: By using these strategies we can predict the possible burden of

the database so we will be able to provide sufficient infrastructure and

process for it. For example with prototyping we can estimate the optimistic

and pessimistic bandwidth in which our application will work properly.

LOS-2: System shall be

scalable

Product Strategies: Modular Architecture

Process Strategies: Prototype each module’s scalability, Using powerful

database which has good scalability.

Analysis: If in all phases of software developing we pay attention to

scalability then we can develop the system in a way that it would be more

scalable. For example with prototyping we can know how our

infrastructure should be scalable to help system’s growth. On the other

hand if we have a modular approach it would satisfy scalability so if in the

future the system needs to be larger, working on small modules is easier

that working on a big whole module.

LOS-3: Search time will

be under one minute

Product Strategies: Optimized code and algorithm, Using Powerful host

and database server.

Process Strategies: Modeling and Prototyping, Performance Analysis

Feasibility Evidence Description (FED) for Architected Agile Version 6.0

FED_IOC1_S13b_T01_V6.0 Version Date: 05/03/13

Analysis: These strategies help us to plan, test and simulate the system to

make sure that its search module performance meets the project’s target.

For example using powerful search algorithms and frameworks and also

having a powerful database engine would greatly help us to reach this

approach.

LOS-4: Downtime: no

more than four hours per

month

Product Strategies: Monitoring the system (after delivery), Regular

Backup/ Recovery , Well design and test to reduce the system’s bugs

Process Strategies: Test Plans & Tools, Regular maintenance

Analysis: By using these kinds of strategies we can use test-based

developing to reduce downtime. For example we can simulate the system

to examine its performance in different situation and queries. Another

approach we are going to use is to design the system is a way that has the

minimum amount of bugs so after delivery we can reduce the downtime

chance. Using powerful test tools also help us in this approach.

After delivering the project we also need to make sure that the system is

monitored and maintenance regular so we told our client that they should

assign an expert person as the webmaster.

3.3 Capability Feasibility

Table 6: Capability Requirements and Their Feasibility Evidence

Capability Requirement Product Satisfaction

CR-1: Custom searchable

database populated from

PubMed

Software/Technology used: Use algorithms for pulling information

through PubMed API, Use MySQL database with powerful search

procedures.

Feasibility Evidence: We’ve planned to use powerful search

procedures (e.g. solr query) to connect to the database, search

among its record and return the result.

CR-2: Search by keyword,

MESH term, author

Software/Technology used: Using key-based search algorithm to

search among database base.

Feasibility Evidence: By using combined SQL algorithms (e.g using

“like” keyword) we request for such query from the database.

Referred use case diagram: UC-3, UC-13, UC-14, UC-15

CR-3: Search member

directory

Software/Technology used: Using a SQL search procedure to search

user database.

Feasibility Evidence: The user’s information is stored into the

database in the “user” table. By connecting to the database (using

php and MySQL) we can create a dataset of user’s information and

after that we can show on the searchmember directory page.

CR-4: User profile page

with list of personal

Software/Technology used: GUI developing Tools, PHP, HTML,

MySQL

Feasibility Evidence Description (FED) for Architected Agile Version 6.0

FED_IOC1_S13b_T01_V6.0 Version Date: 05/03/13

MESH interests, articles,

CV

Feasibility Evidence: For having a good perspective about this

capability we used some GUI prototyping. For developing this

module since all user’s information are stored into the “user” table

into the database, after connecting to the database and getting a

query of each user’s information we can simply show each user’s

information into the “Profile” page.

Referred use case diagram: UC-8, UC-12

CR-5: Discussion board

(posting/responding to

topics)

Software/Technology used: Discussion Board COTS

Feasibility Evidence: We analyzed different types of discussion

board COTS product. We used their demo version. Also we used

weighted matrix to have a better understanding of all COTS’s

capabilities.

Referred use case diagram: UC-4, UC-5, UC-6

CR-7: Personal top-

collaborators list

Software/Technology used: JavaScript

Feasibility Evidence: This module’s implementation is like CR-4.

After connecting to the user table in our database, we have a list of

all users. For this module we just need each user’s collaboration

field. Since we already did some prototyping for connecting to the

database and creating some record sets, now we have good

evidences which make us to feel that this module doable.

Referred use case diagram: UC-7

3.4 Evolutionary Feasibility

Table 7: Evolutionary Requirements and Their Feasibility Evidence

Evolutionary

Requirement

Product Satisfaction

ER-1: Support more users Software/Technology used: PHP, SQL, Database Management

As we discussed in the evidences for LOS-1, we are going to

develop the system in a modular way so if in the future we need

more use supports, the system will be scalable enough to achieve ss

capability.

4. Process Feasibility

Based on our project’s non-conformity points and comparing them to all 4 process patterns, we

can see that the number of non-conformity points in Architected Agile process pattern (4 non-

conformity points) is less than other patterns. It means that our project is more follow

Architected Agile process pattern. On the other hand the importance of these 4 points is medium.

So from all of these factors we can find that we should follow Architected Agile process.

6. NDI/NCS Interoperability Analysis

6.1 Introduction

Member’s collaboration is one of the important parts of our project. After negotiating with client,

we decided to use a discussion board COTS product for this module. After analyzing many

COTS product we found that two of them best match to the client’s win condition, MyBB and

phpBB. After negotiation with client and also analyzing these two COTS product we decided to

use phpBB. In this section there are our assessments about these two COTS product.

6.2 COTS / GOTS / ROTS / Open Source / NCS

Except disccution board COTS products, we are going to use phpMyAdmin DBMS and Apache

Web Server which give us ability to develop web applications.

Table 10: NDI Products Listing

NDI/NCS Products Purposes

MyBB Discussion Board

phpBB Discussion Board

phpMyAdmin Database Management

Apache Web Server

6.3 Connectors

Since our COTS product is an open source software based on PHP, we are going to use PHP to

integrate phpBB into our project. Also for storing data which we retrieve from PubMed into our

local database, we use MySQL.

6.4 Evaluation Summary

As previously discussed, we are going to use phpBB for discussion board forum. This section

contains our comparison assessments. phpBB satisty all project’s win-conditions and level of

services.

phpBB is a popular Internet forum package written in the PHP scripting language . Available

under the GNU General Public License, phpBB is free and open source software. Features of

phpBB include support for multiple database engines (PostgreSQL, SQLite, MySQL, Oracle,

Microsoft SQL Server), flat message structure (as opposed to threaded), hierarchical subforums,

topic split/merge/lock, user groups, multiple attachments per post, full-text search, plugins and

various notification options (e-mail, Jabber instant messaging, ATOM feeds) - Wikipedia

Table 11: NDI Evaluation

Criteria MyBB phpBB Notes

Documentation O + Outdated, many dead links. Simply

poor.

Modding process + O “without editing a single file.” Built for

modding.

Additional features + O Minor. Ex: Inline moderation

Security history O + 151 vs. 6 since 2003

Admin UI simplicity + O ex: drag-and-drop vs. dropdown menus

Comprehensive settings O + advanced settings more easily

accessible

Adding Styles/Themes + O built-in vs. real-time preview website

After analyzing MyBB and phpBB and trying demo versions of them and also after negotiating

with client we found that both COTS are suitable for our project but phpBB has some minor

advantage more than MyBB. So finally client decided to use phpBB. Here are some screen shots

of MyBB and phpBB which we used in our negotiations.
