Smereka is a personal freeform extensible database tool for data mining, project management, collecting notes etc. It allows you to organize your data in an hierarchical, searchable database that is stored in a single file.
Instantly add, view, edit, export and import information items of 5 built-in types - text, formatted text, webpage, file and folder. Plugin interface allows adding new data types, export and import operations.

What is Smereka needed for:
Long-time users of personal computers accumulate a lot of various data. File system is a flexible and universal means of data storage. However, storing information in many separate files is not always a good idea.
If you have a lot of text notes, saved webpages or random files, organizing and navigating them can be difficult. Performing search over those pieces is possible only when you have special search services installed and activated on your computer. Not all of them support tags (text labels which are used by blog-services for organizing posts.)
In case you need to share some of your files with someone else, the recipient won't be able to use your search facility easily, even if it's installed on your machine. You will have to send one monolythic archive, which is almost totally unsearchable, and describe its contents independently in a the letter body.
Moreover, if you work with texts often and use "Word" to type and store your ideas, articles, snippets from the Internet or important emails, then you know how cumbersome it is to launch massive "Office" software to view a couple of paragraphs of text.

How does Smereka solve these problems:
Your files and notes can be stored in a single file - Smereka database. This file is being indexed on the fly, so you can search your information items as soon as they are added to the database. All information items - files, notes and even folders - can be tagged to create "alternative hierarchy".
Extending searching capabilities of "Smereka" is the hierarchical system of item storage (in a tree). This allows you to sort your items into a tree-like structure. You can move, copy items from branch to branch, assign icons to them and more.
Your information (text, offline webpages) appear on the screan instantly, as soon as you click a tree item - you do not need to run an external program in most cases.
And of course, you can share the database. Having received a single file, your peer may instantly browse all the array of your data, search it or export information items to disk.
When should I use Smereka

Here are typlical cases of freeform database usage:
* organizing snippets of text information: you are accumulating small, independent text files and saved webpages. They are used to store ideas, notes, article archive, etc.
* data mining: you are researching some topic. You need to save and analyze a lot of diverse information, which is located on different webpages, in different text files. You also want to save relevant discussions, IM chats etc.
* project management: you are leading a project, which requires organizing and storing a great quantity of artifacts: documents, important e-mails, chat transcripts, ideas, brainstorm protocols etc. In addition to specialized tools, such as MS projects, CMS or bug trackers, a personal database helps a manager to put pieces of informationtogether, which otherwise would not "fit" into these large and formal tools.
* structured information exchange: you need to send your colleague a set of file together with some relevant instructions. You can attach files to the database as info elements, and insert text items as child (or parent) nodes.
