+We parse SQL queries using the certified parser generator written by Jacques-Henri Jourdan and used in CompCert. At the end, we have an SQLCoq-compatible representation of the query. SQLCoq is a Coq library formalising SQL.
+
+%Pour formatter le texte sur \emph{deux colonnes}, utiliser la macro \verb|\twocolsection{<titre>}| si vous souhaitez un titre de section qui fasse la largeur du poster, ou bien \verb|\twocoltext| pour ne pas afficher de titre.
+
+%Vous pouvez utiliser les commandes habituelles à l'intérieur d'une colonne~:
+%\begin{itemize}
+%	\item \verb|\section{<titre>}|,
+%	\item \verb|\subsection{<titre>}|,
+%	\item \verb|\paragraph{<titre>}|.

+\section{Involving DBMS, from SQL to unified execution plan}
+
+We give an SQL query to two DBMS (PostgreSQL and Oracle) and get the query execution plan, that is, the algorithms which are going to be used to fetch the data from the disk.
+
+Then, we change the plans so they have the same format. We defined an unified execution plan format.
+
+%Les titres de sections sont formattés dans la couleur du thème du poster.
+%le trait sous le titre peut être désactivé / réactivé avec les commandes \verb|\titlerulefalse| et \verb|\titleruletrue|.

+%Les titres de sous-sections sont formattés en gris.

+%Pour formatter le texte sur \emph{trois colonnes}, c'est le même principe que pour deux colonnes mais avec les commandes \verb|\threecolsection{<titre>}| et \verb|\threecoltext|.
+%Il faut bien sûr utiliser deux fois la commande \verb|\columnbreak| pour séparer les trois colonnes entre elles, et terminer avec \verb|\onecol|.
+
+\columnbreak{}
+%........................................
+
+From a given plan, we build an Extended Algebra expression. ExtAlg is similar to Relationnal Algebra but more powerful.
+
+Here, the expression is annotated with algorithms. Thus, we'll be able to go further by executing the algorithms which were formalized in Coq.
+
+
+%Vous pouvez insérer des images avec la commande habituelle \verb|\includegraphics|.
+%Quel que soit le nombre de colonnes courant, la largeur de la colonne est dans la variable \verb|\colwidth|.

+\twocolsection{Equivalence of two ExtAlg queries}
+%----------------------------------------
+
+Now we have the ExtAlg expression of the query from the plan the DBMS gave us. We also have the SQLCoq representation of the query. We can get the ExtAlg expression from the SQLCoq representation. We can show the equivalence of the two ExtAlg queries, by using normal forms on logical formulas, or using other Coq-proved equivalence on ExtAlg.

+%Enfin l'environnement \verb|coloredbox| fait la même chose avec une couleur quelconque, passée en paramètre.
+%\end{graybox}
+
+\columnbreak{}
+%........................................
+
+With the equivalence of the two expressions, we are sure that the algorithms that the DMBS planned to use are corrects and that they won't change the semantic of the SQL query. We still have to prove that algorithms used in DBMS are correct, or to use our own written in Coq.

+%========== Sectioning ========================================
+%
+% \section, \subsection and \paragraph are supported
+%
+% Section titles have a line underneath.
+% You can remove it by calling \titlerulfalse before a section title,
+% and re-enable it by calling \titleruletrue.
+
+%========== Graphics ========================================
+%
+% Simply use \includegraphics to include PDF files.
+% It is best to specify the width of the included graphics as
+% a fraction of either \textwidth, the total width of the text area
+% or of \colwidth, the width of the current column,
+% e.g. \includegraphics[width=0.8\textwidth]{<file>.pdf}
+
+%========== Multi columns layout ========================================
+%
+% To format a section in two-columns, do this (the title spans the two columns):
+%	\twocolsection{<sectiontitle}
+%		text .. text ..
+%		\columnbreak	% force a column break (if needed)
+%		text .. text ..
+%	\onecol
+%
+% To format text (without a title) in two-columns, do this:
+%	\twocoltext
+%		text .. text ..
+%		\columnbreak	% force a column break (if needed)
+%		text .. text ..
+%	\onecol
+%
+% Three-column format is achieved similarly with
+%	\threecolsection{<sectiontitle>} ... \onecol
+%	\threecoltext ... \onecol
+% This can be used to have two columns of text and an in the third column.
+
+%========== Colored boxes ========================================
+%
+% To format text on a colored background:
+%	\begin{coloredbox}{<colorname>}
+%	... text ...
+%	\end{coloredbox}
+%
+% Note that in multicolumn layout, you can only put text in colored box within a column,
+% i.e. you cannot have a coloredbox environment around a \twocoltext ... \onecol block.
+%
+% There are two shortcuts for colored boxes:
+%	\begin{cbox} ... \end{cbox}			a box of the default highlighting color (defined by the poster type)
+%	\begin{graybox} ... \end{graybox}	a gray box
