SQL Injection is a trick to inject SQL query/command as an input possibly via web pages. Many web pages take parameters from web user, and make SQL query to the database. Take for instance when a user login, web page that user name and password and make SQL query to the database to check if a user has valid name and password. With SQL Injection, it is possible for us to send crafted user name and/or password field that will change the SQL query and thus grant us something else.

A page in SharePoint is comprised of web parts the exist within zones. Web parts are available for just about everything. For example in the page below there are four web part highlighted by different colors. The purple web part displays a short list of the new announcements stored in the annoucements library. The pink web part displays events from a calendar within the site. The green web part displays an image from a location the user specifies. The gray web part displays a list of links from the links list on the site.

Team sites are small web sites that are created to store everything about a particular thing. For example a site can be created for a department in an organization like human resources. I site can be created for a particular project. A site can even be created for a meeting. Everything about the thing (department, project, meeting) like documents, lists, calendars, etc. is stored in that site.

A library is a feature in SharePoint that stores files (documents). Think of a library as a folder on your file system. For example, a library can be created to store resumes in the human resources team site. A library is usually created for a specific type of file. Libraries can contain metadata to describe the particular file in more detail and to make it easier to find.

A list is a feature in SharePoint that stores a lists of information. For example, a list can be created to store web links in the human resources team site. A list is usually created for a specific type of information. Lists can contain metadata to describe the particular information in more detail and to make it easier to find.

Security in SharePoint is comprised of users, groups and roles.



Users, Groups and Roles

Users
A user account comes from the authentication system. For example, if Active Directory is used to authenticate then the user accounts will come from it.

Groups
There are two types of groups SharePoint uses: domain groups and SharePoint groups.

The SharePoint logical architecure consists of nested and isolated levels. These levels provide benefits for security, navigation, search, branding and ect. depending on the level

SharePoint Farm
The base level for any SharePoint implementation is the SharePoint farm. Physically a farm can consist of one server or many servers. An organization may implement one or more farms. This usually depends on security and performance needs.

SharePoint content types provide users with a way to manage and organize content in a more meaningful way. It's a reusable of settings you want to apply to a particular type of document in a library or item in a list.

The SharePoint physical architecture consists of services running on one or more servers.

Services
There are three types of services that together run the SharePoint farm: web, application and database services. Web services through Internet Information Server is what processes the ASP.Net and sends back the html to a user's browser. Application services is where the "brains" of SharePoint are located. All of the SharePoint specific logic and services are processed there. Database services are run by SQL Server and it's where all the data/content for SharePoint is stored.

The Class Diagram

The class diagram is core to object-oriented design. It describes the types of objects in the system and the static relationships between them.
