A database is an organized collection of data, today typically in digital form. The data are typically organized to model relevant aspects of reality (for example, the availability of rooms in hotels), in a way that supports processes requiring this information (for example, finding a hotel with vacancies).
Dynamic pages
Pages don’t exist as files on disk, on request a program on the server produce code (in the computer memory) and sends it to the user. As a result, the user sees “ordinary” page.

Downsides: the hiring of account on the server, with the possibility of starting programs, and in our case, with access to the SQL database and ASP.NET, costs a little. Perhaps, little more difficult is configuration of such account.

Advantages: few files and, more importantly, you can generate the information on the fly - for example pedigree for the actual person, ones descendants, calendar family with current anniversaries, etc.

GEDCOM (an acronym standing for GEnealogical Data COMmunication) is a proprietary and open de facto standard specification for exchanging genealogical data between different genealogy software. GEDCOM was developed by The Church of Jesus Christ of Latter-day Saints (LDS Church) as an aid to genealogical research.
HyperText Markup Language (HTML) is the main markup language for web pages. HTML elements are the basic building-blocks of web pages. HTML is written in the form of HTML elements consisting of tags enclosed in angle brackets (like <html>), within the web page content. HTML tags most commonly come in pairs like <h1> and </h1>, although some tags, known as empty elements, are unpaired, for example <img>. The first tag in a pair is the start tag, the second tag is the end tag (they are also called opening tags and closing tags). In between these tags web designers can add text, tags, comments and other types of text-based content. The purpose of a web browser is to read HTML documents and compose them into visible or audible web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page.
The culture in Microsoft .Net contains culture-specific information, such as the language, country/region, calendar, and cultural conventions. Culture symbol consists of a language and the symbol of the State, e.g.: pl-Pl Polish language in Poland, en-US: English in the USA.
In most common use, server is a physical computer (a computer hardware system) dedicated to running one or more such services (as a host), to serve the needs of users of the other computers on the network. Depending on the computing service that it offers it could be a database server, file server, mail server, print server, web server, or some other kind of server.
SQL, sometimes referred to as Structured Query Language is a programming language designed for managing data in relational database management systems (RDBMS).
Static pages
All html pages are made as files on the disk.

Advantages: one can use account which all Internet users usually already have to disposal. Configuration of such account restricts to making needed directories and coping files to that account.

Downsides: Abundance of files, if we have thousand persons in our database and all these persons have own file, we ends with thousand of files. Maintains working links between such a numbers of files if difficult for hand, but here, a program generates all the pages with correct links.
